Lake Fulmor
- Location: San Jacinto Mountains, north of Idyllwild. From I-10 in Banning, take the exit for highway 243 (8th St). Follow highway 243 for 15 miles up into the mountains (note that near the beginning, you must take a left on Lincoln St. to stay on highway 243. Make sure you follow the signs). Shortly after the Black Mountain trail head, look for a San Bernardino National Forest sign indicating parking for Lake Fulmor. The lot is on the right side of the street, across from the lake. A National Forest Service Adventure Pass ($5 for a day or $30 for the year) is required for parking. Click here to purchase.

Lake Fulmor is easy to miss – only 3 acres in surface area – but it’s one of those little gems that reminds you that sometimes in Southern California, especially when it comes to nature, there’s more than meets the eye.
The lake sits at about 5,300 feet above sea level, surrounded by scenery that could easily pass for the Sierras, or possibly the Great Smokies. Heck, maybe even the Alps. The tall pines that border the lake are reflected in its still waters, and the scenery is made more interesting by a giant rock poking out of the south shore.
The walking trail goes around the lake, crossing a bridge and passing by a fishing pier. Other than the occasional car passing by on highway 243, the lake is peaceful and quiet. There are picnic tables which make a great place to have lunch before or after the walk.
Fishermen love Lake Fulmor for its bountiful marine life. It has become a go-to destination for anglers fishing for bass, trout, catfish, and bluegill. Here’s a guide from fishingrefined.com that’ll get you prepared, should you want to take up fishing in Lake Fulmor.
Needless to say, the trail around Lake Fulmor is not one of the epic hiking expeditions of the San Jacinto Mountains, but it’s a great little excursion, and a perfect introduction to the natural beauty of the Idyllwild area. Even if you’re on the way to Palm Springs for completely non-hiking purposes, I’d recommend this trip as a detour. Lake Fulmor might not look impressive on the map, but it’s a place that no So-Cal hiking enthusiast should miss.

This one looks really interesting!
Yes – short but very sweet!
Everything the article says is true about this gorgeous little lake. I can’t think of a nicer place for a picnic. I have some knee problems and it was so nice to be able to walk around this lake–the hike might be a half-mile, mostly level, just pretty as can be. There are picnic tables everywhere, a couple bridge-like structures, and a high rock, maybe twenty-five feet, that apparently people jump off in the warm season.
Yeah – it’s certainly an under-appreciated little treasure. Thanks for reading.
Does anyone know if you can swim here? Also is your dog allowed to swim here?
Thank you,
I believe that you are allowed to swim there but double check with the ranger station first.
