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.

Robert Louis Stevenson State Park: Mt. St. Helena Trail

The hike is worth it for the views alone. For the first third of the trail, hiking is at a moderate incline under a large canopied forest. As you work your way up to the breaking tree line, the next two thirds of the hike is even easier but a little more redundant. (Pay close attention where the trail meets the road as there are very few markers at this point and you will need to know this on the way back) This fire road and its surrounding dry chaparral rarely lend any shade breaks for the remainder of the hike. Bring plenty of water and a good shade hat. Every switchback offers remarkable views that get better and better as you progress. Near the top at the saddle where the ridge finally flattens out, you have the option to go left up to the south peak or continue north. Winds can pick up violently here too so tie down your hat! The views most come for are further up the road. Cross the saddle ridge and keep moving up the mountain to the last north peak. Almost there! At the last fork in the road there is a small sign that points left towards a few tall trees that dot the road. Follow that sign, pass through the grove and continue up the road. The incline grows slightly steeper here so take notice of your footing. When you reach the top, enjoy.
- A few other things: The parking lot can get crowded quickly so show up early. Park closes at sunset. Keep the dogs at home. The overall hike is about 10 miles round trip. About 3 hours up and 2.5 hours down average pace. Mount St. Helena North Peak is at 4,339 Feet.

We have done this hike 2 times. Fantastic views from the top. Moderate incline- primary trail is a fire road to the summit.

Table Rock Trail - Palisades Trail to Holm's Place

Actually went from table rock trailhead to Holm's place (6 miles), then descended via oat mill mine road (4.5 miles) to the junction of Hwy 29 and Silverado trail. The last 1.5 miles of the palisades trail before Holmes's place are the hardest part of the trail in my opinion, and elevate the trail to strenuous from moderate. The oat mill mine road trail is all downhill from here but quite rocky/ full of boulders- best done in hiking boots. The views from this trail are phenomenal, the rocks along palisade trail are just amazing. One of my fave hikes ever. All in all, this way it's about 10.5 miles (much better than going back the 6 miles from Holmes's place). However, do leave one car at the oat mill mine road trailhead and drive the other to the table-rock trailhead, you'll need to go back for you car or you might get a warning ticket from the sheriff if you leave your car on the Hwy overnight (personal experience).

If you want a great view of the Napa Valley, this is the place to get them. You don't have to hike very far for some great scenery. Keep going, and you can get to the peak of Mt. Saint Helena and have probably the best view of the valley possible in the area. I have seen a rattlesnake here once, so be aware while hiking.

One of the best hikes in the region. From highway 29 as it passes between Napa and Lake Counties, the trail climbs to the summit of Mount Saint Helena at 4,343 feet in elevation. The peak is the point where Sonoma, Lake and Napa Counties all meet and the views look down over most of the northbay region; you can even see downtown San Francisco on a clear day. The trail follows an access road to the look-out station at the summit, which may make a great mountain bike ride. Check conditions or for obstacles before attempting with your bike.

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.

One of my favorites over the years watching the trees grow back from a fire. This has been a trail run of mine which I have proudly been up well over 200 times. Good views of Napa Valley and on a good day you can see Mt. Shasta to the north.
