Lots of shade for hot summer days, historic century-old mineral spring spa. This is a great hot summer day hike, as this trail provides plenty of shade relief. Check out the remnants of the mineral spring spa. The trail starts paved, then turns to dirt pack. Coming out of the trail brings you along Alum Rock, and back to the trailhead. Some portions of the trails are shared with both bicycles and equestrians. There are some switchbacks, as noted on the map, that make the elevation climb much less strenuous. There is currently a fee of $6.00 for parking inside the park, and dogs are not allowed. This trail is closed on Mondays.

I'm used to mountain biking in Washington so maybe I'm a little biased, but I didn't love this as a mountain biking trail. Some great views at the top, but very little technical work required, mainly just brute leg strength. It was also a little too crowded to get any good speed up without someone being in your way. Not a bad ride, but also not great.

Great morning hike with enough elevation to get the heart rate up. There's lots of shade but it's never too covered up. Tons of small wildlife scrabbling about.

Super fun single track when Penitencia Creek trail turns into South Rim trail. A little too much pavement and can be crowded along Penitencia Creek trail. Some of that can be avoided by taking the North Rim trail and connecting to South Rim.

My very first hike ever back in 2009. Starts off gorgeous, then the sun kicks your ass as you trail uphill lol it's a gorgeous hike with a well-earned view. Don't bring your rookie friends in this hike if you plan on making it to the top.

One of my all time favorite hikes. Not too hard. Great hiking through tree shaded north slope trails. Beware: I have personally had all too close brush with a rattler here. I've also heard credible reports of mountain lion sightings on this trail. Two words: Situational Awareness.

This was my 3-year olds first hike. I'm from San Diego where most hikes are desert (full sun, no trees) and so this beautiful hike with all the trees and the fact we saw deer gets this hike 5 stars! My son made it to the top. I'm so proud. He asked to be carried one time but that lasted about 10 minutes and then he wanted to walk/explore on his own.

Great views of the hills and city.
The South Rim switchback (eastmost part) is currently closed because of a landslide. Looks like you could walk over it but I just turned back as the signs recommended.
Parking is $6 for a day.

Parking is paid and the parking area is usually not very busy, except when groups or families book the picnic grounds for a party.
The trail is understandably dry and dusty this time of the year, but the views from the hill-tops are quite amazing. The trails can be very narrow, especially in the switchback routes, but overall the risk level is not high. If you hike before noon, you'll find that most of the south rim trail is shaded. Elevation is also okay, but it can get somewhat steep in the switchbacks.

The trail is partially closed due to land slide

Very nice for beginners or moderate hikers.
Nice shaded trail with medium incline. The view is excellent through out. Also nice picnic area in the starting point suitable for group activities and barbecues.

By the way the first three parking lots are free and the third (closer to trail) is paid.

South rim trail has nice elevation changes and beautiful scenic views. As I felt like I had not had enough I extended my run to the North - easier and more crowded.

Great moderate hike overall hike from sycamore to south rim to historic mineral springs and a little bit up the north woodland back to our car at rustic landing which has free parking from now until sept 2016 is about 6 miles. Scenic, shady, and light incline but get you worked up within 2 miles in. Great for kids about 10+ and plenty of rest areas. Got to see the groetta mineral springs. Good place to hike in San Jose. A little bit over 2 hours for the hike. No dogs. Bikes and horse back riding trails accommodation.

Good for the kids we started a little farther back cause we were to cheap to pay for parking. My 7 10 and 11 year old kids did it like nothing it's a good start off trail to build staminum

Very good for newcomers to build up endurance.

We had a wonderful hike. Absolutely beautiful. Took all of our kids and hiked all over. Climbed Eagle Rock, did North Rim, Penticienta and the Mineral bath trail. Everyone loved it, kids included. Will be going back for sure!
