Tomales Bay State Park has botanical treasures any time of the year, from the Zen-like environ­ment of the bishop pine forest through mixed hard­woods to ledum swamps and decomposed granite beaches along the bay. Bring your mushroom identification books along too.

Be prepared: Recall the plight of the couple who wandered from this trail on Valentine’s Day 2020 and were lost for over a week. To avoid their fate, please stock your packs with the essential equipment for any hike:

  • navigation (map & cell phone);
  • food & water;
  • protection from sun, rain, and wind (dress in layers w/sturdy shoes);
  • first aid kit;
  • emergency whistle;
  • helpful extras: shelter (space blanket), headlamp, knife, and fire (matches).

Meet at the small unmarked parking area at the top of the Jepson Trail, which is located just south of the entrance to Tomales Bay State Park on Pierce Point Rd. To get there from central Marin, go out Sir Francis Drake Blvd., several miles past Inverness. At the fork in the road, bear right onto Pierce Point Rd., and go approximately one mile to the parking area. If you see the entrance sign to Tomales Bay State Park (Heart’s Desire), you have gone too far, so turn around and go back 200 yards. Heavy rain cancels. Call Ann

King Mountain

King Mountain

King Mountain loop trail, Kentfield
Thursday, March 7, 2024; 12:30 to 4:30 pm     Leaders: Betsey Crawford and Ann Elliott

Please sign up for this field trip  Meetup Registration   Please sign the Field Trip Waiver

 The two-mile King Mountain loop contains multitudes: redwood forest, bay forest, oak canopy, California buckeye, a variety of woodland shrubs, views of Mount Tam and Baltimore Canyon, and even some patches of chapparal. Among the flowers I’ve seen in March are hounds tongue (Cynoglossum grande), common pacific pea (Lathyrus vestitus), death camas (Toxicoscordion fremontii), blue dicks (Dipterostemon capitatum), mission bells (Fritillaria affinis), Iris douglasiana, milk maids (Cardamine californica), monkey flower (Diplacus aurantiacus), morning glory (Calystegia macrostegia), drops of gold (Prosartes hookeri).

King Mountain Loop is a very popular and easy to manage trail with an interesting beginning and end. We will enter at Ridgecrest Drive, which means we will go down a few switchbacks on 106 (I counted) easy-to-use railroad tie steps on the way in. Then up about 300’ (not elevation, just 100 steps sloping up) on the last stretch back to Ridgecrest. The latter is the only tricky part — a bit steep and stepping up some root “steps” at one point.

Directions: Take the Sir Francis Drake exit off 101 north or south. Drive west to College Ave and make a left at the light. College turns into Magnolia Ave. Drive to the junction of Estelle and Magnolia. There is parking in the lot of several defunct stores. We will meet there to carpool.

Bring: Water, snack; hiking poles helpful but not necessary       Rain cancels.        Questions? Text Betsey at 631-484-1949



Rock Spring

Rock Spring

Rock Spring Calypso Orchid Hunt, and More!

Sunday, March 10, 2024, 10:30 am to 2 pm  Leaders: Kristin Jakob & Renee Fittinghoff

Please sign up for this field trip  Meetup Registration   Please sign the Field Trip Waiver

 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.

Mitchell Canyon, Mt. Diablo State Park

Mitchell Canyon, Mt. Diablo State Park

Monday April 29, 2024
Please sign up for this field trip on Meetup. Registration opens April 1.   Please sign Waiver for Marin Chapter 2024.

Mitchell Canyon is one of the wildflower “hot spots” in the Bay Area. This walk will be slow and easy, about 2 miles in length total, three-fourths on the Mitchell Canyon fire road and one-fourth on the single-track Globe Lily Trail.  Please bring your lunch.  After the walk, we will eat at the picnic tables in the shade near the visitor center.

We expect to see the rare (1B.2) Mt. Diablo fairy lantern (Calochortus pulchellus), along with many other spring wildflowers, hopefully including goldenbush (Ericameria linearifolia), broomrape (Aphyllon fasciculatum), blue witch (Solanum umbelliferum), virgin’s bower (Clematis ligusticifolia), colonial onion (Allium unifolium), Sacramento Valley buttercup (Ranunculus canus), yerba santa, wallflowers, blow wives, ookow, silver bush lupine, and more.  If we’re lucky, we’ll also see the butterfly mariposa lily (Calochortus venustus), although we may be too early for that one. And looking up, on the slopes of Mt. Diablo, we’ll see stands of beautiful gray pines (Pinus sabiniana).

The Mt. Diablo Interpretive Association publishes a wonderful online Wildflower Guide. In addition, along the fire road there are ten numbered markers, which are described in this downloadable Mitchell Canyon Trail Interpretive Guide

Carpooling Options: Meet at 8:15 at Mission Avenue Park & Ride in San Rafael or Meet at 8:15 at the Manzanita Park & Ride in Mill Valley
