Ascent Trip Report

Tagged this peak along with Cerro San Luis and Bishop Peak on a 12-mile day starting at Laguna Lake. My wife dropped me off there (we only had one car on our trip to Los Osos), and I did an out-and-back with the three peaks.

0.0 Leave Laguna Lake, take trail north to Little Madonna summit.
0.6 Little Madonna Summit
2.6 Cerro San Luis summit. I dropped down on the north side of Little Madonna, and picked up the main road to the summit. Nice views from the top. Dropped down on the east side of Cerro San Luis, and looped around the north side of the peak, taking a side trail to Tassajara Rd. in the Foothills subdivision of SLO. Then walked the streets to the Bishop Peak trailhead on Foothill Rd, just west of the Baptist Church.
4.0 Tassajara Rd. trailhead
5.0 Bishop Peak trailhead on south side of peak on Foothill Rd.
6.5 Bishop Peak summit.
8.0 Back to trailhead on Foothill.
9.0 Back to Tassajara Rd. trailhead.
9.6 Junction with Rose Garden Trail - turned right and looped around the west side of Cerro San Luis, picking up the trail to Laguna Lake at about 1.5 miles from the lake.
12.0 Back to Laguna Lake.

1 - the day was muggy. SLO was getting their share of the moisture that hit SoCal the day before. I had thunder and rain off and on all day. Lightning wasn't close - only worried about exposure once, on the way down from Bishop.
2 - if I had to do this again, I'd have my wife drop me off at the Highlands trailhead for Bishop, and start there, then pick up Cerro San Luis, and then Little Madonna.
3 - there was a little low Class 2 on the Bishop Peak trail - after about .5 mile from the trailhead, things got steep for about .25 mile. Be careful if you do that.
4 - here's a gpx file visualization at
