Skyline Ridge Preserve
Approximate Total Miles
2.5

This activity has to be canceled due to ADA work at this preserve. Please note it will be offered two more times this season, on Friday, October 11 at Monte Bello Preserve and on Friday, November 1 at Pulgas Ridge Preserve.

Witches’ brooms, oak apples, redwood burls, and stem fasciations—do you know what these are and how they are formed? Welcome to the huge and fascinating world of plant galls! Come along with Docent Naturalists Frances Reneau and Bobbie Riedel on this leisurely-paced exploration along Horseshoe Lake and the Fir Knoll Trail to learn how to spot spined turbans, red cones, pink bowties, and yellow wigs hiding in plain sight on some of your favorite plants. Bring a loupe if you have one.

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.
