Skyline Ridge Preserve
Approximate Total Miles

Join Midpen's Volunteer Interpretive Lead Catherine Caldwell, Interpretive Specialist Katie Renz, and Docent Naturalists Jessica Kolla and Alison Thompson for a fun morning learning about restoration work and connecting to nature. First you'll get hands-on with a little nonnative, invasive plant removal. This will be followed by an interpretive hike around Horseshoe Lake to observe different plants and animals and learn about the interdependencies in action in honor of California Biodiversity Week. This activity is an excellent opportunity for new outdoor enthusiasts and first-time habitat restoration volunteers! Sign-ups are required and will be available on Wednesday, August 6.

Where to Meet

Meet at the Skyline Ridge Equestrian Parking Area on Skyline Boulevard located one mile south of the Skyline Blvd. (Highway 35) and Page Mill/Alpine Road intersection. After entering the preserve, proceed to the farthest parking lot on the left. Those traveling from I-280 on Page Mill Rd. should allow approximately 45 minutes travel time.
