Hi Mountain Trail is a 7.4 mile out and back trail located near Arroyo Grande, CA that offers scenic views. The trail is rated as difficult and primarily used for hiking.
This is my favorite local hike. The location of the trailhead on the map and using directions is accurate. You need a high clearance vehicle. There is a wide spot to park at the top of the hill and the trail starts across the road on the northwest side of the gate. The hike is entirely within wilderness so no bikes. There are oak trees near the trailhead and 1.8 miles in at Hi Valley. Climb to the lookout tower and feel like you've accomplished something. The trail is currently very brushy - I bled wearing shorts.
kind of hard to find the actual entrance to the trail and the locals don't know much about it either and there are no trail entrance markings. we just ended up walking HI Mountain Rd trying to find it. Also, you will have NO Signal so GPS, this app or other guiding devices don't work.
great views of the coast, north slo county, and lopez lake. very very easy drive. dont need 4wd if you come from arroyo grande. at least need a truck if you come from pozo. be sure to check out big falls while you are out there
It was 105 degrees the day we went and there isn't much cover. Go early and take plenty of water. It is well worth the trip to the lookout. There are many ways back, but we chose to go out and back the same route and avoid any walking on HiMountain Rd
