    My daughter found this spot several years ago, when the developers built this community they included this hiking trail which was very smart. Our family has always called the place "Wilson's " because our first time there, a dog named Wilson was there and so cute. We go here often since not many people are not around like the other places in LG. One day we were just taking a different route than the usual and we found a bike park right in the middle, so cool for young boys. There was some junk that someone just threw there, I hate that !!

    Good place to hike with your dog(s), the trails are pretty short, the Valley View trail is 1 mile one way, for their first .5 miles, the trails have a good incline. The Vista Trail is 0.3 miles one way The Skyline trail have a really good view of San Jose It is connected to Santa Rosa OSP, and you can do a longer hike to Belgato park Dog owner, remember to trash your doggie bags in the end!

    If you don't like parking in a nice neighborhood for a safe hilly area with a variety of trails and cool views take a hike.

    Great area to hike and see some great views of the city. Lots of hills, but worth it once you get to the top.

    Not too intense of a trail and nice views of the San Jose area.

There's a separate parking lot at the stables, but you need a permit. *Over ten miles of hiking trails *ADA Compliant trail around the pond in the parking lot. *Horses OK (check trail signage) *Picnic tables in the parking lot *As mentioned above, one of the few places in the South Bay that you can view old-growth Redwoods that doesn't require you to drive down to Felton (Henry Cowell) or Big Basin. *If you're looking for a challenge, the Upper Peter Siemens Trail-Madrone Knoll Trail has an elevation gain of ±1,500' over ±3.5 miles The Meh: *No dogs/pets The Ugly: *Restrooms in the parking lot, but I believe they were vault toilets--don't look down! 0_o Conclusion: Great place to get your hike on if you're in the South Bay and don't feel like a terribly long drive.

In Hamnet, the cave stands as a symbol of that mysterious realm of death, the void from which we come and to which we ultimately return. Yet on this beautiful sunny afternoon, as life breathes through every tree, every leaf, and every small flower, and as I feel the gentle care and encouragement of those beside me, I realized, not in a limbo zone way, that the world, exactly as it is, is beautiful enough. Heaven must be even better. https://youtube.com/shorts/xiQGHA3WKrY?si=womdxeGsiEBLsH0W

    Came here for a hike on the Sunday of Memorial Day weekend! Arrived at the Bald Mountain parking…read morelot around 8:30am and there were lots of spots still available. I went on the Mount Umunhum out and back trail. Still pretty green with some wildflowers! There were a decent amount of hikers, and lots of bicyclists. Seems like a very popular spot for mountain bikers! Had to watch out for cyclists most of the hike. Along the trail, there were some informational posts about the mountain's history and at the summit, there was a neat informational site, Native American pow wow example, and good balcony for pictures. Learned that Umunhum has that name because the Natives thought it sounded like a hummingbird! Partially shaded but I still recommend going in the morning. There were lots of switchbacks so the hike felt long - took me around 3 hours and 15 minutes including breaks to complete. When I came back around 11:45am, the parking lot was full and some people were parked on the side of the road. Overall, I would classify the Mount Umunhum trail as moderately difficult. Because of the switchbacks, the incline is very gradual but the hike feels longer. Good views and trails were well-maintained with markers. The constant cyclists slightly detracted from the hiking experience, but I would still recommend!

    Did the Mt Umunhum trail. Mostly shaded. Free parking. Great views. Some historical stuff (WW2…read moreradar builing and Native American religious site) at the top which is a nice reward making it to the top. Can drive all the way to the top if mobility is an issue.
