Mount Umunhum Trail (from Bald Mountain parking)
This is a moderate out and back trail starting at the Bald Mountain Parking Area and ending at the summit of Mt. Umunhum. For official details, refer to the Mt. Umunhum - Sierra Azul web page. The trail is part of the Sierra Azul Open Space Preserve.
The hike is officially listed as 3.7 miles one-way, but don't be surprised if you end up with an 8-mile round trip. The trail—opened in September 2017—is well constructed and handles water well, great for hiking even after a rainy day. The route gains 1,150' in elevation, the incline is gradual and steady until the top where there are stairs up to the very top.
Most of the trail is in wooded areas although there are enough views of the valley to keep things interesting. The shade keeps things cool most of the way on hot days, and provides some protection on windy days. Once on the summit you'll have a 360º view which include all of Santa Clara Valley and the East Hills, the San Lorenzo Velley and the Pacific Ocean beyond, even San Francisco and Oakland with Mt. Tamalpais and Mt. Diablo in the distance. The one point of interest along the way is the Guadalupe Creek Overlook.
The Bald Mountain Parking Area is on Mt. Umunum Road, 1.6 miles from Hicks Road. Expect slower speeds and winding roads on the way. The parking area has 23 parking spots (1 designated for handicap) which can fill quickly. There's a bigger parking lot just below the summit, another ~3.5 miles farther, for people who only want to climb the stairs to the summit (or drive to the top for handicap parking or to drop people off). There are bathrooms available at this location. There are 23 spaces available (1 designated for handicap). Cross the street to start towards Mt. Umunhum.
Rated 7 of 10 for children. This is an easy hike terrain-wise and appropriate for anyone who can handle walking 8 miles and climbing ~1,000'. But if your children tire easily and want to be carried this may not be the best hike.
