 Join Kristin and Renee to search through the Douglas fir forest looking for the fairy slipper orchid, Calypso bulbosa. The group will explore the trails around the upper Rock Spring meadow, enjoy a picnic lunch around noon, then head down the Cataract Trail as far as participants wish to hike, enjoying other early wildflowers and a diverse array of ferns. Trails are not particularly steep, but narrow and rocky in part, and possibly slippery if wet.

Directions: Meet at the Rock Spring parking lot on Mt. Tamalpais, located at the intersection of Ridgecrest and Pantoll Roads. This is approximately one mile uphill from the state park ranger station at Pantoll; turn uphill across the road from the ranger station. For those unfamiliar with the area, the ranger station is located on Panoramic Hwy. on the way from Mill Valley to Stinson Beach. There is no charge to park at the Rock Spring paved lot, and there are some additional parking spaces along Ridgecrest.

Bring: Water, a lunch, sturdy shoes, and rain gear.    Rain cancels.
