March 31, 2026, Kennedy Trail

This is not a very exciting trail to hike. It’s pretty much a trail surrounded by thick walls of vegetation, with almost no opportunity to view your surroundings. The trail is 70% rocks/gravel, and 30% hard packed clay, so avoid wearing snickers

The Lake Ranch Reservoir is nice and peaceful to run, walk, hike, or bike along. There is a picnic table on the north side of the pond that you could rest at. Since the water is in a small valley, you may want to bring bug spray in the spring/summer months.

From here, you get a great view of the forest and valley, with the Santa Clara Mountains in the background. It’s a nice spot to stop for a picnic and take in the scenery. The trail continues upward, but this spot is perfect if you’re just looking for a good viewpoint.

Forbes Mill Museum, housed in a two-story building of the original 1854 flour mill, offers a glimpse into Los Gatos' history. Built by James Alexander Forbes as California's first commercial flour mill, over the years, it served various roles, including a power plant and a PG&E substation. Saved from demolition in 1982, the building now features historical exhibits as part of New Museum Los Gatos.

From the top of the dam you get splendid views out across Lexington Reservoir. To the north you overlook the winding end of the Los Gatos Creek Trail, which connects to the Jones Trail across from the restroom just up the road. The dam itself was constructed in 1952 and stands at nearly 200 feet tall.
