The vibe at Haypress Campground
Drop some Haypress Campground knowledge on us.
This Place is Decent, It's a first come first serve campground that is accessible by a short 15min .8 mile walk from the parking lot. The camping is free as is the parking. Basically no Shade at the campsites and no fires allowed/ no fire rings but it's free.
Haypress: my ol' reliable when the camping itch strikes but I don't want to drive too far to sleep under the stars. While there is no fee (and a yearly cap on visits), permits are required and can be obtained from the Marin Headlands Visitors Center. They're open til 4pm, but if you can't make it before they close they'll stick the permit in a little drop box outside for you to pick up. At the end of Tennessee Valley Road, you'll find a large parking lot (although this will overflow on the weekends). Follow the paved path .3 miles til you see a dirt track heading back into the hills. After about .6 miles you'll find a clean pit toilet and 5 comfortable sites, all of which are excellent base camps for adventures in the Headlands.
Very accessible, with good access to beach and coastal trails. Subject to the marine layer more than most West Marin coastal locations due to its gradual grade down to the Pacific, so days that may be sunny in nearby Mill Valley many never clear at Haypress. I've twice seen bobcats along the trail to Haypress, so keep your eyes peeled.
