The hike up was awesome! It was shady most of the way to the top. Downhill was mostly open dirt road without much shade.

Amazing trail with lots of variety—beautiful redwoods, lots of waterfalls, arid portions, all without much traffic. Accidentally did it backwards by going right at the first fork. Ended up enjoying doing the steep portions up hill at the beginning and cool down on the leisurely descend.

I did this Jan 26th so it was a little muddy and foggy but overall a beautiful hike but parking is hard to find

I wouldn’t rate this as hard, or really do it again. It was a long trail, but pretty busy and almost always paved. The 2 stars come from the fact that for at least 5 miles (broken up between the middle and end of the trail) there is nowhere to walk except the side of the freeway where there is little to no place to walk. It was pretty scary in some places! Wouldn’t do again.

Sweeping views of Tiburon, Richardson Bay, and SF/fog. Lots of trail variation (fire roads, redwood groves, and creekside scrambles). I went counterclockwise and highly recommend going clockwise instead. Nora Trail was beautiful, shady and mild — would’ve been a lovely ascent. The stretch of Miller Trail was creekside and buggy as hell, and ascending it was not fun. Next time I’ll cut out Miller and will hike Old Railroad Grade to Fern Creek Trail.

Some truly stunning views that only Marin can offer. There’s a mix of sun and shade—but on a sunny day, the heat means business. Bring water, hat, etc. The Miller trail that cuts down to Old Railroad Grade is rocky and a bit overgrown, hence a bit of scrambling but nothing intense. Our small dog managed fine. It’s lovely to stop for a snack at West Point Inn—the picnic tables offer amazing views and a good breeze. We did the trail as marked at it was exactly 4.7 miles

on Dias Ridge

Great hike with consistent incline but the view was well worth it! Took about 2.5 hrs

I took the old railway road to Vic Haun trail and to Temelpa trail up to the east peak. this route gains in elevation in small area.Nice workout with rewarding views of the bay. On the way back, I took the upper Fern trail back to old railway road. There is enough water flowing down and beautiful ferns growing on the banks of the streams to make the hike interesting

Coming back down Miller Trail is a treat. Steep, Wet, Moist, Moss, Ferns, creek. Very cool little unknown return trail. Worth checking out. We love it.

We've driven past this trailhead for years and never stopped to check it out, until 2 weeks ago. Glorious Fall day with clear skies, not very hot, perfect for hiking! Made it almost all the way to Muir Beach before we decided to head back and get lunch in Mill Valley. Saw a garter snake sunning on the trail, always a plus to get some wildlife viewing!

Great hike along the ridge overlooking wood groves. Option to continue to Muir beach at the end, easy parking on panoramic highway

Great hike. Beautiful scenery. Unfortunately, we missed the sign to take the complete Dias Ridge trail and ended on a road. We only missed a half mile of the 6.1 distance, and did not see the water due to fog. We met some seasoned hikers to the area and they gave us several alternatives to try next time. We enjoyed the beautiful wild flowers and cool climate. THERE IS POISON OAK! We are treating with Technu and hoping for the best. I will be back to see this entire path another time for sure.
