Before you head out in Ontario
K1 Speed Ontario
Indoor kart racing
Electric go-karts, two indoor tracks and an arcade make this an active outing for eligible kids, teens and adults. Junior racers must be at least 48 inches tall; adult karts require 58 inches. Staff confirm kart fit, and junior and adult races run separately.
Wear closed-toe shoes. Prepaid Arrive & Drive races are first-come, first-served, not a reserved start time. Check race packages and license costs before buying, and contact the location about private-event closures.
Slick City Ontario
Slides and air courts
Head to Mills Circle for indoor slides and bouncy air courts. Action tickets are for ages 4 and up; junior tickets are offered for children 3 and under. Check which attractions suit each child before choosing tickets.
Choose a 90- or 120-minute action session, bring or buy the required CitySocks, and complete the waiver for everyone entering. A parent or guardian must sign for anyone under 18. Check the Ontario calendar for special sessions and current prices.
Toyota Arena
A game or concert night
Build an evening around the arena's scheduled concerts, Ontario Reign hockey or Empire Strykers indoor soccer. Pick an event first: this is a ticketed venue, not a drop-in attraction.
Check your event's start time and entry rules, then plan parking or a rideshare pickup. Review the arena's bag policy before leaving home. Nearby business lots and neighborhood parking are restricted; use the official parking guide.
Ontario Museum of History & Art
Free art and local history
Visit the city's former City Hall at 225 South Euclid Avenue for local history, art exhibitions and public programs. Museum admission is free; check gallery hours and any program registration before making a downtown visit.
The museum continues welcoming visitors during its North Wing renovation, with the renovated galleries expected to open in spring 2027. Check the renovation update and current exhibitions to see what is available during your visit.
Visitor details checked September 9, 2026. Confirm current hours, prices and entry requirements with the attraction.
