  Something is wrong with the ventilation, the air is THICC with humid chalk feet stench. Do not come here until they fix it.

  The air quality in this gym has become very bad recently, somehow it doesn't seem like there is enough air circulation. You can see chalk dust floating in the air and dropping down through vents. While I love the climbing routes here (kudos to the setters), the air quality is making me having second thought about continuing in this gym. For the price of the membership we are charged, the air quality is much worse than other gyms I have been to where they have some air filtration system (even portable ones). Please install air filter (even portable ones) to filter out the chalk dust and improve the air quality in the gym.

  I really loved the partner climbs, brought along some friends that usually don't climb. I wish they were up year round

  Great space, great yoga classes, huge bouldering wall, clean bathrooms, super friendly staff, great climbing progression classes and often freebies from local vendors in the mornings. Lovely community of climbers. No top ropes at all but always stuff to do and try. They are part of a franchise so you can use any location in the network and all gear is included in memberships and day passes. Great deal generally and you can always get a new member discount.
