From the reviews
I've been to a solid number of climbing gyms at this point, and Monster Mountain has my favorite top rope walls BY FAR. I haven't seen nearly as many interesting features outside of lead climbs. The route setting itself is also top notch - all of my personal "top 5" routes have been here.
A lot of routes with top ropes provided. All you need is someone to belay you. Monday nights are half price for non members! It's fun. All the bouldering is pretty challenging, but a wide variety of top rope routes. Does the trick for a once a week climber
I have really enjoyed climbing here. It's the only place that is literally so friendly that everyone can show up without a climbing partner and have one within 5 minutes even if you don't know a soul. It's a beautiful thing.
This place has a great community. I climbed here often on student night. The people are very helpful for people new to climbing. This is a hidden gem for sure. It is located at the back of Emerald City and it is just a few blocks North of Oak Park Mall. They have recently expanded their hours and that is awesome!
Birthday parties at Monster Mountain
Monster Mountain hosts birthday parties — confirmed on their own site. 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.
