"Trailrun loop. Many trails overgrown with late-spring tall grasses. While still green, everything is starting to fade to yellow and brown, almost as if the water's being sucked out slowly. Still a few weeks left." — scott • May 7, 2025
"Great climb with my dad straight from our house. Really enjoyed hitting the notorious Indian Ladder for the second time this year. We came down on the Mill Valley side and stopped at the Mountain Home Inn for a late lunch on the sunny deck. " — PhoenixMountainLion • Apr 6, 2025
"My first hike in the Western United States. Temperatures in the mid-60s and not a cloud in the sky, which did contribute to a mild sunburn later in the hike. I took an Uber from Marin City to the Muir Woods Visitor Center, although I later realized I could've taken a much cheaper shuttle from Larkspur. The entire hike was fantastic, but the first two miles walking through the redwoods was incredible. Coming from the Northeast United States, I had never seen trees that large. The sunlight filtering through the canopy gave the forest a majestic feel and I was simply in awe at the beauty of the Woods. The trail alternates between boardwalk and paved for the first mile and follows alongside the Redwood Creek (which is largely dried up in the summer). Although this was on a Friday, this section was still packed with people, but I didn't feel that detracted from the experience. After a mile, the trail reaches its last intersection with the Hillside Trail which follows along the other side of the Redwood Creek. Most people took this turn and the trail thinned out. Immediately after this intersection the trail becomes rougher with tree roots and looser dirt, but it was still extremely mild..." — JCalautti • Aug 16, 2024
"If you like hiking in gusty winds, watching dense fog blow across ridges, and having limited visibility, then today was a good day for you in the Marin Headlands. If you like having views of the bay, the ocean, San Francisco, or the Golden Gate Bridge, well, I should have chosen a different day to do this hike. 😉" — michaelwin • Jun 19, 2024
