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.
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.
nice challenging uphill run, killer view from the top
It is a great place to hike:)
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.
It was nice. Saw wild turkeys on the trail, exciting! A little chilly under all of the trees.
Lots of shade, easy incline. Great for beginning hikers who are building up endurance.
