Bouldering Project's Somerville gym, opened in 2013 as Brooklyn Boulders: the chain's only gym with rope climbing as well as bouldering, with lead, top-rope and auto-belay walls, a Kilter Board, yoga and fitness studios, a sauna and co-working space.

About

Bouldering Project's only roped gym

Boston Bouldering Project fills a 38,000 sq ft building at 12A Tyler Street in Somerville, near Union Square. It opened in July 2013 as Brooklyn Boulders Somerville and joined Bouldering Project in 2022, and it is the only one of the chain's gyms with rope climbing as well as bouldering. The roped walls, about 50 feet high when the gym opened, take top-rope and lead climbing, and auto-belays let you climb without a partner. The bouldering walls reach 22 feet, with a mezzanine on top, and a Kilter Board hosts the chain's twice-yearly OB/SESSION board league.

Boulders are set in colour circuits rather than V-grades: yellow, red and green for beginners, purple, orange and black for intermediate climbers, and blue, pink and white for the strongest.

Facilities

  • Weights and cardio equipment and renovated yoga and group-fitness studios; yoga and fitness classes are included with every pass
  • Sauna, and locker rooms with showers
  • Co-working seating
  • Rental shoes, climbing gear, chalk bags and crash pads
  • On-site parking and bike racks, with Green Line trains and buses nearby

Classes and community

Classes run from a short introduction and Bouldering 1 and 2 to Learn the Ropes, which prepares you for the top-rope belay test, and a two-part Learn to Lead course. Youth programmes include after-school clubs, camps, birthday parties and climbing teams for ages 7 to 18. The gym hosted Boston Boulderfest in September 2026 and runs monthly BIPOC and queer and trans climb nights, new-member mixers and a weekly Friday session for LGBTQ+ climbers.
