There are mountain lions here! We were able to take our dog on a leash and did about 4 hours of hiking into different tails. We did notice however that there weren’t many people on the trails which is how we saw the mountain lion taking a nap on the trail. When there’s less foot traffic it can be dangerous. Overall it’s decently covered with trees and the weather can be warm.

♥️♥️♥️

Windy and cooler up at the top, great photo op

Amazing views at the top.

Nice hike. Shaded all the way. One thing i don’t like is that it opens late; it says open and closes at sunrise and sunset, so you won’t be able to go there to see the sunrise. Bummer!

Easy hike, rolling hills, but nothing hard. Dog allowed on a leash.

It is a decent trail and is easy to moderate. I started at 3 PM and hardly found anyone on track as compared to morning counterpart. Initial trail has buzz of electrical lines which is distracting to an extent but the ascent keeps you occupied. There isn't any scenic view apart from the valley view which points where the concrete jungle is. Path is well marked and in between you get patches of trees which is a real solace in hot sun. After first 4 miles with the elevation gain of 1.7k feet, it is normal decent back to start point.

Great trail for a morning run. Minimally technical terrain with only a few rocky spots and one narrow section allow for opening up a stride on the descent. The only downside is that the minimal shade makes it get hot quickly. Run the big loop to the summit clockwise (straight at junction) for a gentler downhill or counterclockwise (right at junction) for a steeper downhill but gentler uphill.

Very good hike to prepare you for any hard hikes you have planned!!
I’ve used it to prepare me for Half Dome and Sedona.
I enjoy the hike at least once a week in the Horse Heaven Trail, it is less congested with people.

Too crowded

Tough for a beginner, all uphill, but a great trail!

My new favorite. Hard, but gorgeous and rewarding.

Accept it as your first challenge

all time favorite ..good incline and fully shaded .

A great morning hike, has a decent amount of ups and downs, views of SJ and even downtown in some spots. Parking is on side roads and the trail is decently crowded on weekends. Sunny trail mostly with a couple shaded areas. A lot of mining history to see and ruins of some mines.

This is a fairly straightforward hike. The trail is well maintained and not too heavily trafficked, especially early in the morning (i.e. 7am). The ascent is very gradual to the top and not strenuous with the exception of a few sets of stairs to reach the summit. The summit gives some great views of the surrounding area and some information on the history of the area.

Overall, this is a good hike that can be done fairly quickly and offers some good views.

It was a well maintained, shaded trail. There were a couple of really nice scenic view points...and deer! Caught glimpse of a creepy, rusted wrecked car on the way back...did someone drive off the main road and roll down the cliff?? I wish the building at the summit was open to wander around in...but overall a good hike!

Santa Rosa trail is currently severely overgrow with dried plants. In some areas over 6ft high. Use caution.

Great hike or a train for running. Bring more water than you think is necessary as it’s 75% open, especially if you’re doing it on the hot day like we did. Otherwise great views and really good wide path most of the way. Great for kids too and there are benches to rest at peaks.

It is a great place for trail running, could be crowded mornings and evenings

Hiked, walked and jogged these trails dozens of times. Lots of wild life to be seen!

This was really hard. The views of the bay were pretty cool, but the views while hiking were kind of dull. Just a lot of dry grass and cows. The trail is well maintained. Watch out for cow dung and bees!

Gates are locked at sunset!

Super dusty but not an issue for a solo person. Anti-clockwise worked well for me as I like to walk the steeper uphills. More shade on the final leg of the counter-clockwise loop but not by much.
Observed: two tarantula

take the southern Loop first thing in the morning when you set out, and your return trip will be on the north side of the Hill and in the shade.

Great hike, good views.. would be better if it for the smoke :-(

Surprisingly great route for a quick run after work. Improved by returning via Saratoga Gap Trail to mix things up a little.

typical fire road trail hike. quite steep and little to no shade.
