Pretty hard uphill. And down hill is not easy on the knees either. Great view and quiet.

Gorgeous trail. Streep incline and good workout. Nice views. Very limited parking.

As long as you don"t bother about loud motorcyclists and the fact that the trail is all the way near HWY 9 OR 35 you can enjoy the 4.7 miles loop.

I’ve walked this just after sunrise and just before sunset.
AM it is best to go clockwise, PM best anti-clockwise.

Great hike! Beautiful scenery, especially on the way back up!!It feels like I was hiking around the hill. There is some sun but most of the trail is shady. First mile is straight up which is hard but it flattens out and descends which is okay. At the bottom is a small area to hang out/picnic/community garden. There is also a barn which has sheeps and goats which are fun to see. Trail is not marked well!! Can be cold during the winter at the top! Small parking lot of about 10 cars total. I found a spot on a non holiday weekend Sunday at around 1130am, otherwise find parking in the neighborhood.

Lovely views. Road noise can be
Loud at times

Really scenic, very beautiful and not too hard to hike (tho some parts get a little steep).

Make sure to note that the park closes 30 minutes after sunset, and the rangers will begin to give tickets after this.

Great hike..nice views...if you have a dog-comb them for ticks afterwards..not too many, but be cautious..

great walk but at the end we saw the sign saying no dogs! so maybe remove the dog friendly tag.

Great hike. Initial hike is a bit steep, but it levels out after the first mile.

Beautiful trail! Signs aren’t very clear, so definitely check Google maps or AllTrails at intersections.

Also note: the parking lot is small and was full, so we ended up parking a mile away. As a result we had to cut the loop short because we were running out of daylight, but it was still great.

Trail head easy to find - start of the hike goes up and up - backside of the hike was really nice fall hike - i would come back again

I did counterclockwise with having a little detour to enjoy Stevens Creek Natural Trail. Indian Creek Trail has steep gradient and was challenging with almost no shade. But view from black mountain was great. There were not many shade through the loop except Stevens Creek Natural Trail. Recommend to hike in the morning and finish before noon if temperatures exceed 90F.

Recommend going clockwise on loop to avoid doing 100% elevation all at once.


Good and relatively easy workout to reach black mountain. 5 miles round trip if you reach the black mountain and come back. 6 miles if you meander around at the top for some time. Doable in 2-2.5 hrs. Open trail, hence best if completed before noon in summers.

Nice one. If you plan on doing the loop, all of it, it is very diverse. Tight paths, steep ones, flowers, waterfalls...
Medium hard...but relaxing.
Get your maps or apps because the signs along the way are pathetic.

This loop is a bit of a challenge for kids under 10yo, but doable as a 3-5h walk. It definitely has enough variation to keep them interested for the whole distance. Alpine Pond is a good midpoint, and it's possible to shortcut the loop there if the ascent to Borel Hill turns out to be too much. During our visit in early May we saw amazing wildflower displays, lots of birds and two coyotes wandering near the trail.

Beautiful trail. Nice wildflowers. Didn't see mountain lion.

I took us around 3 hours to do this loop with children (so multiple stops and small detours). No outstanding features, but pleasant views and a stream for part of the loop. A lot of wildlife these days in the preserve: we saw more than 10 deer, some wild turkeys and a coyote in the early afternoon. Also many birds, butterflies and wildflowers.

The 1st mile is straight up which was challenging. Then you get to a lovely meadow and have a lot of options. There are lovely wildflowers, and I didn't see any wildlife but there were signs posted about recent mountain lion sightings that advise people not to hike alone. It was nice and shady, and good for a hot day. I'll definitely go again.

Small parking lot, with overflow parking about 0.4 mi away at Foothill college. The initial 0.9 miles is a steep incline. When you turn off towards Hidden Villa after 0.4 miles, you make your way down again to the creek. With all of the rain right now, it is a very relaxing trail along the creek, until you head up Ewing Hill, and then make your way back. When it is hot outside, portions are under direct sun and can be pretty hot.

Visited hidden vila and the trails after few weeks of rain. The creek was full and flowing fast which was an amazing view! The farm is very nice and suitable for young kids.

best trail to do practice for long hikes. you can start at Pg&e and reach black summit via quarry trial. that makes its 12.5 miles of round trip. Do it twice and you are ready for any hike around in the range of 22-25 miles.

Scenic views and several different trails you can hop on. Great for trail running and getting a good hill workout.

This is a fairly easy trail with many short sections. A 3+ mile loop will only gain about 400' in elevation. A couple of nice views but mostly you're in a mixed forest. The San Andreas Fault trail, a loop, will take you by a fence which has shifted over 3' from the ground movement of the '06 quake. When leaving the trail head closest to Skyline, take the left hand route and you'll see the best view you will see while on the hike. This is a good hike for someone not looking for a lot of elevation gain. It's not flat by any means but probably one of the flattest hikes in an area with lots of hills. It gets 4 stars for being relatively flat and for the earthquake loop.

Entered from the Hidden Villa side. Walked the "Creek Trail." Continued onto the Black Mountain Trail. A little bit of incline but basically a mellow hike along a charming creek with a tree lined trail. About 1.5 hours.

Nice hike through oak woodlands and meadows. A little climb from the moody road side brings you into the meadows. A trail continues up black mountain, and you can also access rancho San Antonio

This is a nice trail with good views to the east and a good hike down to the end of Alpine Rd. Plus, dogs are allowed on leash. Winter/spring is a good time to hike Coal Creek but can be a bit muddy.
