This is easily one of the best trails in the area. Killer views the whole way, and at the top an absolutely amazing lookout spot perfect for sitting on a rock and having some lunch. Very fun for hiking and mountain biking. On the way down you can go extremely fast on your bike without having to worry about it being too technical.

An all day hike. The fall and spring are the best times for this trail.

By far one of my favorite hikes around the valley. It does get crowded on weekends so get there early. Trail is a bit rocky and is a good climb but levels out once you get to the ridge. Good all year long, but bring lots of water and sun protection on hot days.

What’s left of Holm’s homestead is a bit if a let down but this hike was amazing and I would definitely do it again. The views were spectacular. Trail was very rocky and lots of mountain bikers. Mile marker 4 has the best view.

Great Hike. Mountain Bikes also use this trail. No definite summit or peak. Old wagon wheel marks visible in the rocks on the way up. Great views nonetheless.

I wouldn't call this trail hard per se, but it is quite technical and fairly long. The uphill is gradual, but extended.

The views around mile 5 are out of this world, and worth the trek up! Wear good, sturdy boots because the upper portion (after mile 4) gets very rocky and uneven. This is a classic ankle - breaker!

Watch your step, but don't forget to take a look at the awesome scenery. Calistoga gets warm quick, so start early in the day for an enjoyable hike.

The earlier you get there, the easier it is to find parking. The trailhead only has room for about eight cars!

We did the first 4.5 miles starting at about 9 in the morning. By the 4.5 mile mark it was getting hot and the shade was gone and my dog was not enjoying the hot sun so we turned around. There were still lots of wild flowers, awesome views and plenty of shade the first and last 3 miles. You can still see wagon wheel ruts in the trail and we enjoyed the flowers and views. There were some mountain bikers and trail runners and they were all polite and respectful. I kept the dog on the leash as it is a bad year for ticks and there is lots of poison oak off the trail. It also kept her from bothering the runners and bikers.

Lovely hike, steadily uphill (but not sharply so) with some nice scenery. First 3 miles are mostly shaded. I only went 4 miles due to time constraints. Trail is rocky—glad I had hiking boots so I wouldn't turn an ankle.

Steep uphill at the start moderates about the 1 mile mark.

Awesome hike first part is somewhat hot but you get random bits of shade throughout. Best view is a little after the fourth mile! Breathtaking views there. But from mile 4.5-6.2 not much going on honestly if you're not up for the whole thing hike to mile 4.5, soak it all in.. Then go back. Also good hike for dogs but right after mile 4 it gets rocky for a bit.. But me and my pooch made it! Fantastic hike!

One of my favorites. Great hike/trail run. Low traffics after mile three and great views.

Hot, rugged and rocky but worth it for the views and Pallisades

Saturday, May 07, 2016

Trail is uphill the whole way, but a nice, moderate incline with plenty of shade along the way. I hiked until the trail split off to the Palisades trail, ate lunch and admired the view, then came back down. All in all I believe I took about 5-6 hours to complete the hike. The views of the valley and the palisades are beautiful. Next time when I have more time I'd like to do it as part of the greater Palisades/Mount Saint Helena hike. Definitely recommend!

*Be mindful to stay on the main trail, otherwise you encounter a LOT of poison oak. This was a wonderful hike, we went fairly early in the morning, didn't see a lot of people, walked a few miles, would definitely recommend.

This is a nice hike but not too intense. It is a steady climb that is certainly a moderate or above level. Fortunately, the incline begins right away so beginners won't get too far before they realize they are in over their heads. There are numerous trails that lead off the main one but still get you to the top. A constant view of the valley helps you decide which of the trails to take as there are few markings. For some reason, people think that leash laws don't apply to them so be prepared for dogs running up to say hello.

Our first attempt at this trail, and only made it about halfway due to a late start on the day. Still, it is one of the more beautiful, scenic hikes in Napa Valley. It is solidly a moderately difficult trail as it is steadily uphill from the valley, albeit at a very temperate incline. The trail is mostly wide enough for easy passing, though it is rocky with loose rock, so wearing good hiking shoes is a must. The trail is well maintained. It winds in and out of shade, so is very comfortable. The vistas as you climb are incredible, getting up high enough that you can look all the way down Napa Valley. We're really looking forward to going the full distance one day soon. Very highly recommended.

Enjoyed this hike. Easy to Moderate difficulty. Watch out for bikes. The trail is narrow and they come down fast. Wear good trail shoes as their are lots of fist sized loose rocks. Great views of Calistoga. Equal areas of sun and shade. Definitely recommend to anyone looking for a relatively easy hike to see the expansive views. Parking for about 8 cars.

Favorite haunt of local mt. bike riders. Technically challenging.

Great Trail run. I have seen large Rattle snakes on this trail quite a bit so watch out. Big ones can be in a rather foul mood! This trail is hot in the summer and is long but lot of fun.

Beautiful hike with breathtaking views. The homestead wasn't as great as we thought it would be. Long up hill hike! It got a little dicey on the way down with all the rock on the trail. Really fun!
