This hike is really the perfect day hike if you are in the mood for scenic views rather than intense canopy. There isn't much shade on this hike so I'd definitely recommend a hat, sunscreen, and most important water. Given that, I'd say that this is one of my favorite "lazy Sunday" types of hikes. It's not intense, but it's not flat either. It's a great hike to go on a picnic with your SO or a small group of friends.

The views are incredible, and this hike is beyond gorgeous when it's green out. We went in late March 2018 and were the only people on the trail somehow. You can see San Francisco easily if it's not a foggy day, you can see Mt. Diablo, and you can see most of Marin as well as some glimpses of the ocean. All in all, I'd say that this is one of the best scenic hikes around.

Really like the hike however dont use my upload - tried to extend the hike by a few miles and the trail on the map I wanted to use is blocked with no trespassing AND a camera. Easy trailhead to find, trail in good condition, get there early and see the sun rise. The hike is pretty much a fire road but the views are amazing on Marin's second highest ridge. Almost zero cover so start early or bring sunscreen. I will hike again in the winter

This app labels the miles and elevation wrong. The trail isn't even a full six miles and the elevation is less than the 2K indicated. So it wasn't the workout I was after, but the views were really pretty once you get to the actual loop part and it was very peaceful as few others were around.

okay, I only saw one hiker. Definitely nice for solitude, not much but rolling hills as far as views go. Didn't fall like 2000 feet gain....
