This is part of an ongoing series about the various staircases, and stair streets, of SF. See all installments here.

Putting the "jungle" in "urban jungle," a secluded staircase on 22nd Street between Diamond and Collingwood Streets might be one of the wildest places in San Francisco. Unexplored by most, a new cohort of public garden enthusiasts have been tending to the stairs since 2012, bringing them out of obscurity while retaining their overgrown, "tropical urban oasis" aesthetic.

The so-called "Jungle Stairs" are an SF Park Alliance sponsored initiative of neighbor volunteers led by project directors Ken Fisher, Marc Snyder, and Barry Taylor. On their website, they've been keeping track of their sometimes uphill climb to improve the stairs, from cleaning up debris to planting sustainable flowers and succulents in their effort to ensure the stairs' enduring beauty.

Most recently, the group wrote in June that they'd be meeting with the SF Parks Alliance and the Department of Public Works to discuss applications for irrigation changes. You can reach out to help with volunteer days, or if you're just swinging by sometime, maybe pick up any trash you see.

Finally, while it's easy to get lost in the flora of the Jungle Stairs, make sure to look around.The view from 22nd at Collingwood of Twin Peaks and Sutro Tower might be the wildest aspect of all.
