Just north of San Francisco and the Golden Gate, is Mount Tamalpais State Park (MTSP), 6,300 acres of redwood groves, oak woodlands, grassland slopes, chaparral and rocky ridges. Offering spectacular views of the nearby Pacific and the surrounding San Francisco Bay Area, from its ridges, slopes and the 2,571-foot high, East Peak.
Located in the very heart of Marin County, Mount Tamalpais State Park (MTSP) offers a wealth of activities, including picnicing, California nature study, historic landmarks, hiking, biking, tent camping, horseback riding, group camping, overnight cabins, and two almost 100 year old inns (West Point Inn & Mtn. Home Inn), just over its boundary lines. With close by beaches for sunbathing and a dip, a tidal lagoon offering kayaking, as well as surfing in or just bordering the park, activities abound!
Astronomy nights are offered monthly, April through September, with lectures and stargazing/star party events, and even public storytelling for children and the young at heart, at Rock Spring Parking Area and Mtn. Theatre. - all the above programs are free except parking fees at Pantoll Ranger Station, Bootjack Parking Lot and the East Peak Parking Lot, horseback riding charges, overnight accomodations and camping fees.
From mid-May to mid-June each year the Mountain Play Association offers a revival of a Broadway musical, featuring professional theatre personnel, recreating the great American musical theatre, high on Mt. Tam. Shows are presented in the 5000 seat, outdoor, Mountain Theatre.
We've done this hike with the kids. You park at the parking lot across from the Mountain Home (Panoramic Highway). Take the paved road on the north side of the Mountain Home and hike up the paved trail towards Throckmorton Ridge Fire Station. Continue on the paved road, past the fire station & head West on the Matt Davis Trail. Then follow the Nora Trail to West Point Inn. This is where a few Sundays a year, you can get a pancake breakfast and support a good cause- Check out the website for The West Point Inn for more details. There are other ways to hike in, but this is the way we've gone. The views to the ocean are spectacular. The trail is shaded in most places. It does take about an hour or so to hike out there (not too steep, fairly level) and the same back. Wear layers and bring lots of water. You can actually stay at the Inn but we've never done so.
We did go for a walk around the peak of Mount Tamalpais. The way is all paved so you can walk around the peak with a stroller. The walk took us about 30 to 40 minutes. There is no guard rail, so be careful with toddlers.
This stroll offers stunning views over the Bay Area and the Pacific. We loved the sunset. There is a picknick area up there and a visitor center. The area is sometimes closed because of fire danger, so it is recommendable to call the ranger station ahead. Also, it is better to check weather conditions before going up there.
