Come join me in taking on Black Mountain in my old neighborhood in the Los Altos hill at Rancho San Antonio.
This will be a 14+ mile hike that will loop us around the park.
I created a link below to a custom map I created on All Trails.
Bring plenty of water, dress for the weather, and lets have a good time.

There will be an informational Zoom meeting on Thursday 5/14 at 7pm for all. Please mark yourself as going to receive a link to the meeting.

Full disclosure I am NOT a professional guide or leader. Please consider your ability, skill, and endurance no matter how good you think you are. Fatigue, dehydration, etc. can happen to anyone. EVERY hiker is responsible for THEIR own safety, directions, and pace they hike. EVERY hiker is responsible for themselves for everything that happens to them on the trail. This is a self paced hike. We don't always stay together and are not obligated to. I create hikes on All Trails and invite everyone to join me. We laugh, make fun of ourselves, take lots of pictures, and have a good time. This is your hike to enjoy!
Please message me if you have any questions.
Hope to see you all there!
