Frog Lake Loop Trail is a 4.2 mile moderately trafficked loop trail located near Morgan Hill, California that features a lake and is rated as moderate. The trail is primarily used for hiking, walking, trail running, and nature trips and is accessible from September until June.
The best introduction to Henry Coe State Park south of San Jose and Silicon Valley, California Henry Coe State Park is all peaks, ridges and valleys, and its reputation for arduous treks is well deserved. Frog Lake Loop is the one shining exception. While the hike starts with a 400-foot ascent and continues with a knee-crunching 600-foot descent, the return leg is serene by Henry Coe standards. The midpoint is Frog Lake, a great place to watch for wildlife and listen for the trademark knock of the acorn woodpecker. Frog Lake Loop is bound to whet your appetite for further forays into the wilds of Henry Coe. Just bear in mind this is one of the easiest routes in the park. Best time to go: Springtime, when the wildflowers are in bloom, and October/November, after the heat of summer has departed. Winter can get too muddy, and summer can be too hot.
Try it counter-clockwise for a tougher finish back up Hobbs road before the switch-backs down to the visitor center which adds a nice view to the wind down after the climb. The only reason not to give it 5 stars is that you are on a road. But that's just me as I prefer trails when I'm hiking.
It was a nice 1.5hrs walk. Once you finish first 15min uphill and then steep downhill and get down to the lake it's an easy nice walk through the woods back to HQ.
Just moved from DC so Henry Coe trails were only second ones hiked in the area. Frog Lake Loop was the first of three trails we hiked over MLK weekend. There was a gradual accent on Monument Trail as described but not too bad. Beautiful views at the apex. Ironically, I found the short but steep descent into canyon to Frog Lake where the trail merges onto a service road more challenging part of the weekend due to the loose gravel. Not overly steep but actually lost my footing on the loose rock a couple of times, so was comic relief for anyone within viewing range. Granted, picking rocks out of your hands from time to time is just part of hiking. However, a little easier on the ego doing it from some back-woods unimproved trail than strolling down a freakin “improved” gravel road. Though not quite as remote as I'd hoped, the trail itself was nice overall. Next time I'll hike the loop counter-clockwise to ascend that road and hopefully reclaim my pride.
Awesome views. Lots of frogs
