The Crosstown Trail’s southern terminus is at the Sunrise Point fishing pier inside Candlestick Point State Recreation Area. This little-known park is worth exploring. If you’re willing to take a slight detour, you can visit the Endangered Garden, a concrete promenade created by public artist Patricia Johanson that pays tribute to the endangered San Francisco Garter Snake. The promenade continues along the shoreline to the Sunnydale water treatment plant. It’s worth the trip to check out the art and the view.
Following the main Crosstown Trail, you’ll safely cross Harney Way at a crosswalk. (Going north, this is how you leave the park; going south, this is how you enter the park.) But you’ll miss the Endangered Garden, a few yards west of the crosswalk. Feel free to explore it, but please do not attempt to cross Harney Way here. Return to that crosswalk to the east!
The alternative route below shows you how you can find the Endangered Garden, walking along the shoreline instead of the road, and return to the crosswalk.
