Bouldering Project Somerville grades, explained

BP's Boston-area gym is on Tyler Street in Somerville, a few blocks from Bow Market. It is the only Bouldering Project with rope climbing as well as bouldering; a day pass or membership covers both, plus system boards, weights and yoga and fitness classes.

Bouldering grades

Boulders are set in colour circuits marked by hold colour: Yellow is the easiest and White (or Mint, at some gyms) the hardest. Each colour covers roughly three V-grades and neighbouring colours overlap on purpose, so circuits are not a strict ladder. The ranges are read off Bouldering Project's grade chart; only Purple is also given in its text.
