Spread along the bluffs and banks of the Illinois River, Peoria is the state's oldest European settlement and the largest city on the river, a working Midwest town that grew up around Caterpillar's heavy-equipment works. Its riverfront carries a genuine museum, a paddle-wheel heritage, and downtown streets that climb to wooded ridgelines within a few minutes' drive of the water.
Peoria rewards a visitor who mixes indoor culture with river-bluff scenery. You can spend a morning among the collections of the Peoria Riverfront Museum, an afternoon on the two-and-a-half-mile Grand View Drive that Theodore Roosevelt praised, and an evening under a big-top tent at Corn Stock Theatre. These are the 25 best things to do in Peoria, from Glen Oak Park's zoo and botanical garden to the Fulton Sheen cathedral downtown.
Peoria's Riverfront Museum resists a single label. Opened on the downtown riverbank in 2012, it folds fine art, natural science, local history, and a planetarium into one building on the Illinois River. The art holdings span paintings and sculpture through Native American, African, and Oceanic works, while the history galleries run from early motorized vehicles to a replica of Neil Armstrong's space suit.
Under the museum's 40-foot Digistar dome, planetarium programs play out for stargazers, and the adjoining Giant Screen Theater runs one of the largest film screens in the country. A 400-gallon aquarium stocks native Illinois River species alongside displays on the river's history, and the Schoenheider Goose, a famous cast-iron hunting decoy, sits among the collection.
When Theodore Roosevelt visited Peoria in 1910, he called the two-and-a-half-mile Grand View Drive "the world's most beautiful drive." The road still delivers on that, tracing the bluff edge above the Illinois River past historic homes and hardwood forest, with the water opening up between the trees at nearly every turn.
Grand View Drive doubles as a linear park, so a paved path shadows the road for walkers, runners, and cyclists who prefer a slower pace than a car. Dogs are welcome along it, and the greenway threads together picnic tables, playgrounds, baseball diamonds, and volleyball courts on the strip of land between the drive and the river bluff.
The Peoria Zoo sits inside nineteenth-century Glen Oak Park, and its roots reach back to a herd of elk donated to the city in the late 1800s. Long called the Glen Oak Zoo, it was renamed the Peoria Zoo after a major expansion in 2009 that added its African section.
That Africa exhibit is home to giraffes, gazelles, zebras, and rhinos, with separate areas for lions and several monkey species. The Australia Walk-About lets visitors move among Australian animals and hand-feed budgies in a walk-in aviary. The wider Glen Oak Park around the zoo holds a children's museum, the Rotary Adventure Grove playground, an amphitheater, and a lagoon.
Forest Park Nature Center leads walkers straight into the wooded bluffs above the Illinois River, and its seven miles of hiking trails wind through more than 500 acres of dedicated Illinois State Nature Preserve. The upland forest makes it one of the best birdwatching and wildlife-viewing spots in the Peoria area.
At the trailhead a natural-history museum hosts talks and workshops, often led by groups such as the Audubon Society and the Sierra Club, and a bird-observation room gives visitors a warm vantage on local species. The Trailhead Nature Store stocks field guides and mementos. Pets are not permitted on the preserve trails, which helps keep the wildlife close.
Peoria's Louisville Slugger Sports Complex is built for players as much as spectators. Its 125,000-square-foot Slugger Dome holds synthetic softball fields and volleyball courts under one climate-controlled roof, so leagues and tournaments run year-round regardless of Illinois weather, alongside batting-cage rentals and open floor space.
Outside the dome, the Slugger Stadiumplex adds championship softball fields with seating for 1,300, in-ground dugouts, an LED scoreboard, and backstop netting that give it a professional feel. Adult recreational leagues at the complex cover softball, volleyball, kickball, and soccer, and the venue draws travel-ball tournaments from across the Midwest.
The Peoria PlayHouse is the city's children's museum, opened in 2015 inside a Glen Oak Park pavilion and built entirely around imaginative, hands-on play. At the Fossils Rock exhibit children dig through real fossils like paleontologists, and the Peoria, Then and Now area lets young visitors ride a train and stage a vaudeville show from the city's past.
Staff trained in art and history work the floor, turning open-ended play into learning for kids of every age. Whether they are running loaders and dump trucks at the construction exhibit or harvesting pretend produce on the family farm, children steer their own visit while the Peoria PlayHouse keeps the emphasis firmly on discovery rather than instruction.
Docked on the Illinois River in East Peoria, the Par-A-Dice Hotel Casino is a four-deck riverboat casino with a smoke-free gaming floor. Nearly a thousand slot machines and around thirty table games keep the boat busy around the clock, and three onsite restaurants feed players between hands.
The table lineup runs to blackjack, craps, roulette, three-card poker, Mississippi Stud, and Mini Baccarat, and an onsite sportsbook takes wagers on the major U.S. leagues. Guests who want to stay put can book one of the 202 rooms in the attached hotel, making the Par-A-Dice a full overnight stop rather than just a gaming floor.
Tucked inside Glen Oak Park, the five-acre George L. Luthy Memorial Botanical Garden gives visitors a quiet, cultivated break from the city around it. Its beds are organized into distinct sections, among them an herb garden, a rose collection, a viburnum planting, and an all-season garden, with a tropical conservatory sheltering plants that could never survive an Illinois winter outdoors.
Across the year the Luthy stages flower shows built around orchids, chrysanthemums, and poinsettias, giving the conservatory a fresh look with each season. For home gardeners, the staff offer landscape consultation on pruning, fertilizing, and pest control, and the garden hosts a steady run of educational programs and community events.
At Corn Stock Theatre the show goes up under a genuine big-top tent on the grounds of Laura Bradley Park. Corn Stock is an outdoor community theatre that runs both a summer season in the tent and a smaller winter season indoors, staffed and performed by Peoria residents.
The company opened in 1954 with a production in Detweiler Park, then partnered with the Peoria Park District and moved to its permanent home in Bradley Park the following year. Its stated aim is theatre by the community, for the community, and its Corn Stock for Kids program mounts two shows and a summer workshop each year to bring the next generation onto the stage.
Ever wanted to ride a two-and-a-half-story construction machine? A visit to the Caterpillar Visitors Center opens with a virtual ride inside a Caterpillar mining truck. Set downtown a short walk from the river, the center tells the story of the equipment maker that has anchored Peoria's economy for a century.
Beyond the company history, the exhibits put guests inside the heavy machinery that has built roads, buildings, and infrastructure worldwide. Simulators let visitors take the controls of several Caterpillar vehicles, and an interactive station invites them to design a machine of their own, making the center as hands-on as it is informative.
Wheels O'Time is a 30,000-square-foot museum devoted to vintage vehicles of nearly every kind. It began in 1977 as a home for antique cars, and its early Packards, Ford Model Ts, and Chevrolets have since been joined by fire trucks, bicycles, and aircraft, along with a Rock Island steam locomotive and heavy Caterpillar equipment.
Because most of the collection was sourced from the surrounding area, Wheels O'Time doubles as a record of Peoria's own industrial past. The museum has kept growing over the decades, adding a 5,000-square-foot building in 2020, and its clocks, jukeboxes, and mechanical oddities round out a lineup that goes well beyond cars.
12. Betty Jayne Brimmer Center for the Performing Arts
The Betty Jayne Brimmer Center for the Performing Arts is one of Peoria's more recent additions, built around the shell of the old Peoria Heights Library and opened in 2019. As a dedicated performing-arts center it stages musical theatre, concerts, drama, and lectures through the year, and it stands as a visible piece of the area's community-renewal effort.
The center is named for the mother of developer Kim Blickenstaff, who led the library's renovation. Betty Jayne Brimmer herself was a vaudeville performer and dancer during Peoria's Big Band era, so the naming closes a loop between the building's new life and the city's entertainment history. Checking the event calendar is the best way to catch its programming.
The village of Peoria Heights perches on the bluffs above the western bank of the Illinois River, and Grand View Drive runs along its edge. Compact and walkable, the village center is lined with independent restaurants and shops that draw visitors up from the riverfront below.
Beside the village hall stands Tower Park, a green space anchored by a 200-foot water tower whose three observation decks, reached by a glass elevator, open panoramic views across the river valley. The park's gazebo hosts live performances, and both Forest Park Nature Center and the Rock Island Greenway lie within easy reach of Peoria Heights.
Built in 1868 for the abolitionist Moses Pettengill, the Pettengill-Morron House is one of Peoria's finest surviving nineteenth-century homes. A strong example of Second Empire architecture, it carries an imposing Colonial Revival porch and stands as a window into the city's mid-1800s prosperity.
Inside, displays recount the abolitionist work of Moses and Lucy Pettengill. Pettengill, originally from Salisbury, New Hampshire, began as a teacher before making his fortune as a hardware merchant and builder, and family artifacts remain in the house. A later resident, Jean McLean Morron, left additional antique furnishings to the Peoria Historical Society, which now operates the house as a museum.
From its southern trailhead on the Peoria riverfront, the Rock Island Trail runs thirteen miles to the northwest of the city. Apart from one short on-street stretch with a dedicated bike lane, the multi-use path stays off-road for nearly its whole length, linking the Riverfront Museum with the Caterpillar Visitors Center and passing Springdale Cemetery and Glen Oak Park along the way.
A longer, wilder section of the corridor picks up at the Kickapoo Creek Recreation Area near the community of Alta, north of Peoria. This northern stretch is managed as an Illinois state park and carries walkers, cyclists, and runners past scenic overlooks and stands of restored prairie.
The Peoria Historical Society's John C. Flanagan House Museum is the oldest standing house in Peoria, built in 1837 by local judge John C. Flanagan in the Federal style. Inside, period furnishings and collections of antiques recreate an authentic nineteenth-century domestic setting.
The Peoria chapter of the Daughters of the American Revolution keeps its headquarters in the house, and local tradition holds that Abraham Lincoln stayed here during the era of the Lincoln-Douglas debates. Historical Society volunteers lead tours of the John C. Flanagan House Museum on a regular basis, and the home is also available for private event rental.
The multi-use Peoria Civic Center opened downtown in 1982 to a design by the noted American architect Philip Johnson, and it has anchored the city's event calendar ever since. Its 10,000-seat arena serves as home floor for local basketball and hockey teams, and its stated purpose is to support Peoria's economy and quality of life through the events it draws.
Conventions and trade shows fill the center's 100,000 square feet of exhibit space, while its theatre and concert halls host the Peoria Symphony Orchestra and Peoria Ballet. A steady slate of touring Broadway productions rounds out a program that keeps the Peoria Civic Center busy across all four seasons.
Detweiler Park spreads over 740 acres just north of Peoria along the Illinois River, with more than five miles of hiking trails offering a fast, quiet escape from the city. Sports fields sit alongside a boat ramp and a riverfront beach where visitors fish, sunbathe, or watch for birds on the water.
The park carries real history under its trees. A massive redwood log, hauled to the area by the Caterpillar company in 1915, remains a local landmark, and Detweiler Park itself was established in 1928 in honor of steamboat captain Henry Detweiler. The captain's nineteenth-century icehouse still stands on display within the grounds.
On Peoria's northwest side, Charter Oak Park is built around the 6.4-acre Charter Oak North Lake. Anglers fish the lake from the shoreline and three small piers, pulling in largemouth bass, bluegill, red-ear sunfish, and channel catfish from its stocked water.
Away from the water, Charter Oak Park lays out a short network of paved and gravel hiking trails, plus courts for basketball, pickleball, and tennis and open soccer fields. Leashed dogs are welcome throughout, which makes it an easy, low-key green space for Peoria residents and visitors staying on the northwest edge of town.
20. Cathedral of Saint Mary of the Immaculate Conception
Modeled on St. Patrick's Cathedral in New York City, the Cathedral of Saint Mary of the Immaculate Conception rose between 1885 and 1889 as the mother church of the Diocese of Peoria. Its limestone facade anchors the city's North Side Historic District, and the cathedral has been listed on the National Register of Historic Places since 1983.
Guided tours can be arranged through the Museums of the Diocese of Peoria. Next to the cathedral sits the Fulton Sheen exhibit dedicated to the Peoria-raised Catholic broadcaster and Servant of God, whose remains were entombed at the cathedral in 2019 following a restoration of the historic interior.
Chartered in 1855, Springdale Cemetery is the oldest chartered cemetery in Illinois and one of Peoria's most atmospheric places to walk. Laid out across 225 hilly, wooded acres as both a burial ground and a public park, it holds nearly 70,000 graves along more than six miles of winding roadways and is listed on the National Register of Historic Places.
The rolling grounds double as an unofficial arboretum and a record of Peoria's past. Guided history tours, several departing from the Caterpillar Visitors Center, lead visitors to the resting places of the city's soldiers, athletes, educators, and civic leaders, while self-guided drives let you take the ridgelines and ravines of Springdale Cemetery at your own pace.
Set in quiet Donovan Park, the Northmoor Observatory was the first observatory in Illinois opened to the general public. Its nine-inch refractor telescope dates to 1913, and though it has since been updated and reassembled, a rotating dome added in 2009 keeps the historic instrument trained on the sky. The Peoria Astronomical Society now runs the site.
On clear Saturday evenings, Northmoor Observatory holds free public viewings, with society volunteers guiding guests through the night sky. Donovan Park around it is a destination in daylight too, offering picnic tables, walking trails, and a public shelter for a relaxed afternoon before the stars come out.
The Pekin community lies just south of Peoria across the Illinois River, and its Park District is a network of thirteen parks covering more than 2,500 acres. Pekin Lake itself is a state reserve that draws a wide range of wildlife, and Mineral Springs Park sits at the district's heart with a landmark pavilion set beside a lagoon.
Recreation runs deep across the district. DragonLand Water Park packs a three-acre complex of pools, waterslides, and play areas, and the wider system adds the Happy Trail Dog Park, Memorial Stadium and Ice Arena, a senior center, and a racquet club, giving day-trippers from Peoria a full slate of activity on the river's south bank.
Built by the Army Corps of Engineers in 1951 to shield Peoria from periodic flooding, Farmdale Reservoir sits three miles east of the city. The flood basin stays dry most of the year, and when it is, its fifteen miles of trails open to hikers, mountain bikers, and horseback riders; after heavy rain the area closes while it does its real job of holding back water.
The Corps has overseen a deliberate return of native tall-grass prairie across the site, and with hunting prohibited, wildlife moves freely over Farmdale Reservoir's 837 acres. That combination of restored grassland and long, quiet trails makes it one of the better places near Peoria to spend a half-day outdoors.
Peoria's Lakeview Park and Recreation Center gathers a surprising amount under one roof on the city's west side. The recreation center holds courts for basketball, pickleball, and volleyball, a dance studio open for community use, and four classrooms used for workshops, education, and events.
An indoor ice-skating rink runs at Lakeview alongside the Peoria Players Theatre and a branch of the public library, so the park works as much as a civic hub as a sports facility. The Peoria Park District keeps its administrative offices here, and the Girl Scouts of Central Illinois are headquartered on the same grounds.
