"My wife and I wanted to check out a new trailhead that we heard about. As we were driving up to the TH we climbed about 500 feet. We were laughing about it because my wife was excited for the free climb and I was grumbling about how the car was eating into my elevation gain. I'm sure she would love to start here again...but I know the TH has likely seen the last of us! " — jeffreybossaller • Apr 30, 2023
"The day started off with nice clear skies. By the time we got an hour into our hike it began to pour. It lasted about 25 minutes but the damage was done. We were soaked. Fortunately my wife planned for this and brought a waterproof jacket. I did not. Oh well. At least I had time to dry off a little before the hike ended. " — jeffreybossaller • Mar 11, 2023
"I started my hike at 2:00pm and got backl to the car at 7:30pm. I hiked most of the day and ran for about an hour. It was a gorgeous day with perfect temperatures for a long hike. I watched part of the Sunset on Hawk Hill and finished it on Lower Hawk Hill. This was close to the longest hike I have done in the Marin Headlands. I got back to the car after dark and then decided to shed the backpack and do the last two peaks (Peak 197 and Peak 360) after dark with a headlight on. This completes my 50 Peak Challenge and I really appreciate the effort that was put in to getting this challenge set up. It was one of the coolest things I have done." — jeffreybossaller • Feb 25, 2023
"Great loop trailrun up Yolanda to the short steep Buddha trail, then up and over supeaks to the flat summit of Baldy. Down other side and back on Yolanda a tad after sunset. Days are so short right now, barely had light to type this. " — scott • Dec 7, 2022
"Quick run from East Garrison to West Garrison to bday cake/cannon sendoff. Hit Mount Livermore and Point Stuart Hill en route. Incredible views of SF and the bay; reflection from water so intense could feel its heat." — scott • Nov 13, 2022
