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

You can expect a mix of unpaved surfaces, including gravel paths, dirt roads, and some steep inclines.

Some sections, like those near the reservoir on the Los Gatos Creek Trail, can have grades up to 45 degrees.
The routes highlighted in this guide are generally considered difficult due to significant elevation gain and varied terrain.
