Not marked at all so make sure you download the map before you start. It’s a rough way up and steep way down. Not a lot of shade at certain points so make sure to wear sun screen. Not sure if we took the right way back, because we went down a thin little valley path to get back

We ended up walking from our hotel in San Rafael and did not arrive to the trailhead until mid morning on an early June day that happened to be very warm. Bring plenty of water and sunscreen. Despite the heat and full sun it was worth the effort. Hawks and eagles can be seen catching the currents and there were plenary of beautiful vistas. Trail signs are not existent so make sure you study the map before you get started.

FitBit tracks about 145 "floors", but it feels like more than that! Spectacular views at the top make the brutal ascent worth it.

This is actually steeper than we thought it would be. Creeks beautiful and great yo water doggies.

Mostly fire road and steep but it's close to home and a good workout with some good bay and Novato views.

Great hike. Go clockwise for shade on the way up. Our only issue was bringing older parents. This trail is really steep so not for the out of shape.

We hike this loop at least once a month, going up what's marked as Queenstone Rd up to the Fire Road, over to Big Rock Ridge and then down the trail which we've dubbed "Goat Trai" since you'd need to be a billygoat to come UP that way. It's a great workout and some very nice scenery especially on the way down as the road winds around the crevasse back down to the stables off Rubicon.

A beautiful, steep climb up a natural steep canyon. We only had an hour, and after an hour and a half, we were still climbing, hoping to get to the fire road. We think we were close, but turned back and went down the same way we came. We hiked up and down in about two hours. Count on 3 full hours to do the whole loop. It's a beautiful, natural environment, with great views, and much shade along the way.
