Cosmic Adventures is Ottawa’s largest indoor playground — a 20,000 sq. ft. multi-level facility in Gloucester, on the east end of the city. A family-run operation with more than 30 years in the Ottawa community, Cosmic is purpose-built for children ages 0 to 12, with a massive soft-play structure, two dedicated toddler zones, an arcade, a full restaurant, and a parent lounge all under one roof. Families can drop in for play any day of the week, join the Cosmic Kids Club for unlimited annual access, or book an all-inclusive birthday party in Ottawa complete with Party Heroes, arcade credits, and cake. School groups, daycare outings, and summer day camps are also part of the Cosmic calendar — making it a year-round destination for families across Ottawa, Gloucester, Orleans, Barrhaven, and Kanata.

Attractions & Play Zones at Cosmic Adventures Ottawa

Multi-Level Soft Play Structure

🎯 Recommended Age: 3 to 12 years

The heart of Cosmic Adventures is its enormous multi-level soft play structure — one of the largest of its kind in the Ottawa region. Spanning the bulk of the facility’s 20,000 sq. ft., the structure features an interconnected network of slides, tunnels, mazes, obstacle courses, and climbing elements, all heavily padded with no sharp corners. Kids can explore independently or with friends, navigating different levels and discovering new routes on every visit. The open-ended layout encourages physical activity, problem-solving, and imaginative play without any structured agenda.

Two Dedicated Toddler Zones

🎯 Recommended Age: 0 to 3 years

Cosmic Adventures features two separate areas designed specifically for babies and toddlers, geared to their developmental stage and motor skill growth. Each toddler zone includes exersaucers, baby tunnels, a tot tree, and mini ball pits — all scaled and padded for the youngest visitors. Even pre-crawlers benefit from the colourful, stimulating environment. The toddler areas are separated from the main big-kid structure, giving parents confidence that their little ones can explore safely at their own pace.

Starcade

🎯 Recommended Age: 4 to 17 years

The Starcade is Cosmic Adventures’ on-site arcade room, featuring a variety of skill-testing and redemption games where kids can aim for high scores and trade in their winnings for prizes. The non-competitive format keeps things fun for all skill levels, and birthday party packages include arcade credits for each guest. It’s a great complement to the soft-play structure for kids who want a break from climbing.
