"Friendly neighborhood spot. Supportive community, approachable staff, and lots of fun routes at a wide variety of difficulty levels'

Connor

"Plenty of wall for everyone at half moon. Even during high volume times you can find a section of wall to yourself or talk to all the wonderful people around you. There is a whole wall in the back for the really young climbers"

Aidan

“Awesome gym, changed my membership from a bigger and more crowded gym as Half Moon is much less crowded and friendlier. Lots of routes and the climbing classes are awesome."

Guillermo

"As a parent, I appreciate the program's focus on challenging the children to push their limits, both physically and mentally. The skills she's gaining extend beyond the gym, teaching her problem-solving, resilience, and determination. This bouldering program not only promotes a love for the sport but also instills important life skills in a way that makes learning enjoyable for the kids. I highly recommend this program!"

Aurelie

"Halfmoon Bouldering is my favorite Seattle climbing gym. Climbers are friendly and community oriented but the gym never feels overly crowded. I like that the walls aren't too high but the routes are creative enough that I can challenge myself in the small space.
Their yoga classes are also great and they are included in the membership"

“I have been climbing for over a decade and this has been my favorite gym by a mile. It feels like a really community in here”

Matt

"I have been going to Half Moon for 2 years and it has been exciting to see it grow. It is the most welcoming community and I’ve enjoyed interactions with other climbers and the staff. For me the real gem is the yoga program— the studio is comfortable and clean, there is a great variety of teachers, and many class times to choose from. Considering the classes are included in the membership, it’s a great value."

Mallory

“The best community oriented climbing gym! Super friendly staff, coaches, and community events just about every month.”

merv

We moved to Halfmoon after some classes at a different bouldering gym. Our daughter wanted instruction to push herself as a climber. The pebbles classes have exceeded all of our expectations, the instructors are kind and fun but hold the classes accountable. The skills that she has developed have by far been the most fun to watch.

Alicia

Very kind and welcome staff + good set of fun boulders!
