Nothing new here, that other reviews have not said, but "metoo" is useful.
I have been coming to Elk Lake for years, only over nighting since 2022.
The road in is paved asphalt, just one lane and a bit narrow. The host is in the first spot, but we did not talk to them. Others said the host was nice. The toilets and sites were clean, the dumpsters had room for more trash. The road narrows down near the day use area, and people park on the road, so I suggest cars only down to that area.
The site was roomy for my 25' motor home, I backed in with the help of a spotter. I was titled 2.8 degrees to the side, and 1 degree down in the back. Easily fixed with my jacks. Lots of cure chipmunks, some fat. Nice a quiet, only a little highway noise during the day. A short walk to the toilets and water, a little further to the say use area and beach, then a bit more to the lodge. The lodge restaurant closes at 6:30pm , so don't miss dinner like we did.
There was a bit of smoke from the Bedrock fire, not enough to drive anyone away. For a few hours you could not see Mt. Bachelor. The lake is clear and warm. Good kayaking. The wind can come up, and turn, in the afternoon, so keep a weather eye. Some bugs on the lake edges, but nothing that bit me.
Most people we met were locals, or regulars. Several were walking the PCT and had come to the lodge for provisions. All we mete were nice. My dog played with some of the other dogs.
Some of the reserved sites were nover used. Please cancel if you are not going to make your reservation!.
My T-Mobile bounced from 5-bars of LTE to 1-bar of 5G and back again. Voice and SMS good, web pages were slow.
