Join us for City Nature Challenge at El Polin Springs! Help us record and observe wildlife in the vicinity of this beautiful, restored natural spring.This bioblitz involves moderate to difficult off-trail hiking, as well as navigating tripping hazards and uneven terrain. Hazards include potential exposure to poison oak, tripping hazards, yellow jackets, and stinging insects (though we will make every effort to avoid all of those things!)

This and all of the other activities that make up City Nature Challenge 2019 at the Presidio are free and open to the public. All ages welcome! Some activities require registration.
