Struck down but not out by repeated closures due to the pandemic, Black Rock remains a local climber's best resource when real rock is unavailable. Laid out in two cavernous rooms with slightly different offerings, the 15-foot walls provide challenges to everyone, whether it's your first time in rock shoes or you're the next Alex Honnold. There are no ropes and no use for a harness here. When you fall, you hit the (padded) ground. Sooner or later, you'll lose your grip on a crimper hold atop one of the color-coordinated boulder problems and down you'll splat. (You have to practice falling to get it right.) We find the ratings here a touch softer than at other gyms — to be specific, we have climbed V4s here, and only here, but those were unforgettable moments, endearing us to the place forever. The vibe is perfect, with a good mix of young monkeys, scruffy veterans, and tattooed daredevils of both sexes with rippling muscles. Social distancing rules apply, and hand-washing is mandatory.
