Hiking Big Rock to Cowles Mountain

I decided to hike up Cowles Mountain via the Big Rock Trail. Believe it or not, I have actually never taken this route up Cowles as I generally take the Baker Way route when I care to climb this peak. I pulled into street parking and gathered my gear. It was still a bit chilly and the first part of the ascent would be on the northern slopes of the mountain. The trail passed by the dog park and the empty paddleball courts. Then the trail split, and the left fork climbed a short hill, while the right path skirted it. Off in the distance stood the communication towers next to the summit of Cowles Mountain.

The trail crossed a dry creek before beginning its real climb and I cruised along the fairly well maintained path. As the trail worked its way upward, I was afforded some nice views to the north – Woodson, Iron mountain and El Cajon Mountain were all standing tall.

I soon came to the junction with the Mesa Trail but stayed on the Big Rock Trail. Once it reached the service road, the warmth of the sun was enough to have me shed the light fleece I had been wearing. I had a short flat stretch before the road began its fairly steep climb to the summit, as it is designed for trucks and not hikers. As I reached the summit I took a moment to soak in the views. It was a very clear day, and standing atop the highest point in the City of San Diego offered up some nice vistas. After snapping a few photos, I extended the length of my trekking poles to assist with the steep descent and headed back down.

The return went quickly, and I gave friendly nods to others as they made their way up. As I neared the paddleball courts, they were now filled with players. I collapsed my poles and turned off my tracker. It recorded the trip as 4.8 miles in 1:56 (including the time at the summit).


I am an avid peak bagger, sometimes backpacker, and former sea kayaker living in San Diego. In 2019, I became the third person to complete the San Diego 100 Peak Challenge. Not stopping with that accomplishment, I set my sights on the harder San Diego Sierra Club 100 Peak list, which I completed in 2021. In addition, I have conquered several Six-Pack of Peaks challenges (SoCal, San Diego, Central Coast, and Arizona-Winter). Beyond attempting the San Diego Sierra Club 100 Peak list a second time, I am looking forward to exploring new summits and new adventures across the southwest.
