Flying Squirrel Ottawa vs. Cosmic Adventures: Which Ottawa Indoor Park Fits Your Crew?

Ottawa families are spoiled for choice when it comes to indoor fun for the whole family. Two of the biggest names—Flying Squirrel Ottawa and Cosmic Adventures—both promise a full day (or night) of fun. They just deliver it in different ways. Here’s a fair, side-by-side look so you can pick the right spot for your family, your budget, and your occasion.

The vibe: high-energy jumps vs. giant soft-play

Flying Squirrel is a wall-to-wall trampoline and adventure park. There are giant trampolines for freestyle bouncing, dodgeball courts, dunk hoops, airbag jumps, balance challenges, and climbing elements—plus glow sessions on weekend nights. There’s also an onsite cafe and arcade. It’s built for movement and scales nicely from little kids to tweens, teens, and even adults.

Cosmic Adventures is an indoor soft-play playground. There are multi-level slides, tunnels, mazes, obstacle courses, and dedicated toddler areas, with an on-site arcade and café. It’s tailor-made for younger kids and unstructured exploration.

Bottom line: If your group skews older or mixed-age (say, 6–16, plus parents who want in on the action), Flying Squirrel offers more ways to play together. If your day is all about toddlers and early elementary kids who love to climb, crawl, and slide, Cosmic shines.

Who has the broader age range?

Both parks welcome families, but they emphasize different stages.

• Flying Squirrel: Great for kids, tweens, teens, and adults. There are kid-only zones for the littles, but the main attraction is suited to bigger energy and coordination too—so older siblings don’t age out, and parents can jump in rather than just supervise. 
• Cosmic Adventures: Ideal for toddlers and younger kids. Older kids can have fun, but the attractions are designed primarily for younger bodies and attention spans.

Edge: Flying Squirrel, for keeping older siblings (and parents) engaged without “I’m bored” after 20 minutes.

Size & space: How much room do you really get?

Flying Squirrel Ottawa operates on a much larger footprint—about 57,000 sq. ft.—which spreads guests across multiple trampoline courts, challenge zones, and seating areas. On busy weekends, that massive space usually means shorter waits, easier supervision, and room for mixed-age groups to do different things without tripping over each other.

Cosmic Adventures is a 20,000 sq. ft. multi-level soft-play playground. It’s sizable for younger kids and perfect for climb-crawl-slide exploration, but it’s a more compact experience overall—great for keeping little ones in sight, though older kids may run out of “new” areas more quickly.

Takeaway: If you want a venue that scales for toddlers through teens (and parents) with room to spread out, Flying Squirrel’s larger footprint gives it the edge. For younger-kid days where cozy visibility matters more than variety, Cosmic’s size fits the bill.

Parties: which makes hosting easier (and cooler)?

You’ll get private space, a host, and food options at both venues. The difference is what guests actually do during the party.

• Flying Squirrel: Kids birthday parties at Flying Squirrel typically include lots of jump time, structured transitions, and easy crowd-pleasers like dodgeball, indoor rock climbing, foam pits and dunk hoops. Families love that friends of different ages can all participate—and that the birthday kid gets highlight-reel moments. Weekend glow sessions add a bonus “wow” factor for older kids and teens.
• Cosmic Adventures: Parties revolve around the play structure and arcade time, which is perfect for younger groups. It’s very plug-and-play for the host parent, with predictable flow.

Edge: Tie. Both are fun for families.

Variety and replay value

One reason families become regulars is variety—the sense that each visit can feel fresh.

• Flying Squirrel mixes free play with mini-challenges: try the dunk lane, rotate into dodgeball, attempt a balance run, progress to a bigger airbag jump, or add climbing time. The format naturally creates short, repeatable goals and friendly competition.
• Cosmic Adventures emphasizes open exploration. Kids loop favourite slides, find new tunnels, and enjoy “I can do it myself” independence.

Edge: Flying Squirrel, for built-in progression that keeps tweens and teens asking to come back—and for adults who want more than spectating.

Safety and comfort

Both venues take safety seriously with rules, staff supervision, and equipment designed for their style of play.

• Flying Squirrel: Waivers, grip socks, padded landings, and clear zones help keep high-energy fun controlled. Younger kids get dedicated areas; parents can assist on the floor where needed. 
• Cosmic Adventures: Socks-only, shoe-free play areas, age-appropriate structures, and a layout tuned for visibility and supervision. Especially comforting for parents of toddlers.

Edge: Tie. Different approaches for different kinds of motion; both are thoughtful about it.

Food, coffee, and catch-your-breath moments

Refueling and regrouping are part of family outings—and both parks make that easy.

• Flying Squirrel has café options and seating where parents can recharge between rounds (including massage chairs), plus an arcade for brief resets.
• Cosmic Adventures features a kid–friendly menu and plenty of places to perch while kids orbit the play structure.

Edge: Tie. Choose based on whether your crew needs short “fuel breaks” between high-energy play (Flying Squirrel) or a longer café anchor while tots roam (Cosmic).

Value for your situation

Value isn’t just price—it’s fit. Ask: Who’s coming? How old? How active? What memories are we trying to make?

• Choose Cosmic Adventures if your group is mostly toddlers and early elementary kids who want to climb and slide for hours with minimal structure. It excels at gentle, imaginative play with lots of room to explore.
• Choose Flying Squirrel if you’re mixing ages, including teens or adults, or you want a party or outing that feels like an “event.” The combination of trampolines, challenges, and glow nights creates bigger moments and better photos—without leaving younger siblings behind.

The verdict

You can’t really “go wrong”—Ottawa is lucky to have both. But if you’re after one destination that grows with your kids, keeps older siblings and parents engaged, and turns birthdays into genuine highlights, Flying Squirrel Ottawa is the better long-term fit. It delivers the broadest age range, the most ways to play together, and a steady stream of “let’s try that next” moments that bring families back.
