Endless Fun is one of Durham Region’s largest kids’ indoor play centres, located at 400 Monarch Avenue in Ajax, Ontario. Spanning 10,000 square feet, this facility packs in a 3-level climbing and play structure, a fully padded toddler area, laser-gun bumper cars that adults and kids can enjoy together, an arcade, and the Endless Café — all under one roof. The addition of a large banquet hall alongside four private party rooms makes it one of the few indoor playgrounds in Ajax that can genuinely accommodate both an intimate kids’ birthday and a large family celebration at the same time.

Endless Fun is open Tuesday through Sunday for drop-in play and birthday party bookings. For current admission pricing, visit endlessfun.ca or call (905) 239-9992. Multi-visit play passes with per-visit savings are also available — call or visit in store to purchase.

Attractions at Endless Fun — Ajax Indoor Playground

3-Level Play Structure

The centrepiece of Endless Fun is a massive multi-level climbing structure packed with slides, mazes, spider climbs, cannon balls, and a trampoline section. Reviewers frequently highlight the toboggan section as a standout feature not commonly found at other Durham Region play centres. The structure is designed to keep kids independently active for hours.

🎯 Recommended Age: 1 year and up

Toddler Area

A fully padded, dedicated zone scaled for the youngest visitors, keeping little ones safely separated from the higher-energy areas of the main structure while giving them age-appropriate challenges to explore.

🎯 Recommended Age: Toddlers and under

Laser-Gun Bumper Cars

One of Endless Fun’s most distinctive offerings — bumper cars combined with laser guns, playable by both kids and adults together. It’s the kind of attraction that gets parents off the sidelines and into the action alongside their children, and a genuine differentiator among kids’ play centres in the Durham Region.

🎯 Recommended Age: School-age and up (age/height requirements apply)
