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.

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.
