This was a truly amazing spot. The sweeping mountain views on each side, along with direct creek access was great. It was mid July and 105 degrees in Big Pine when we left the 395 highway, but temps had dropped to 88 by the time we got up to the campground due to elevation change, so it is a great way to escape the heat if it is a hot day.
We stayed in site #17, which had the river rolling right by the picnic table. Sites 16 - 19 all had good water access, and I'm pretty sure a lot of the sites in the upper loop could access the river too (didn't get a chance to check it out in person though).
The road getting up is steep, narrow, and climbs almost 3500 feet over the course of 7 miles. If you are towing a trailer or driving a big rig get ready to burn some gas, and make sure you have solid brakes for the way down. No guard rails, so a few of the places I was white knuckling it just towing our small 22 foot travel trailer. Definitely still worth it, just something to keep in mind. Not all of the sites will fit an RV either, so pay close attention to the lengths when reserving.
Despite the challenges getting up there, this is still one of the best places to camp in the area, would highly recommend.
