From the reviews

Never knew this place was here but it was a great place. We came for a birthday party and everyone had a blast. The staff was awesome and very helpful not to mention engaged with the kids making sure they had as much fun as possible. We will be back for sure.

Awesome course after awesome course here, the staff change the layout of obstacles daily, and new ones are added constantly. The coaches are super energetic, helpful, and are actively trying to help you do your best and set new records.

★★★★★ — Tyler, Feb 2024

Upward is a great place for kids and adults wanting to do American Ninja type exercise and obstacle challenge including a mega warp wall, as well as a 8',10',12', and 14.5' warp wall. A very friendly and clean environment. Price is affordable for the amount of fun.

★★★★★ — Stacey, Dec 2022

Training to Serve... indeed they walk the talk and not just talk the walk. Is such a peaceful place. My girls are so happy. Especially now, during their Summer camp. If you haven't visit the grounds... I 💯 recommend it!

Birthday parties at Upward Ninja and Bouldering

Upward Ninja and Bouldering hosts birthday parties, going by their listing and visitor reviews. Climbing parties come with staff who handle the harnesses and belaying, so parents can mostly watch. One thing that's different here: every guest needs a signed waiver — send the gym's waiver link to the other parents when you send invites, or check-in day gets slow. Packages, party rooms, and pricing change often, so check the current options and book ahead — weekend slots go fast at popular gyms.
