We stayed here for one night in December. It was a great location not far off the interstate. We stayed a few hundred metres along the dirt road on a flat area between juniper bushes. It was lovely and quite.
We stayed here for one night and it was a great spot, really quite. The road was a little rough to get to where we stayed but no issue in our van aside from being a bit bumpy. We stopped about 2 miles from the main road. We arrived in the dark and it was a little tricky to see where we could and couldn't stay. We turned right off the road and found a flat open space with a fire ring. There was nobody else there. In the morning we could see some RVs further along the path and assume this is the proper site but we had no issues staying where we did .
Checked with a couple of members of staff that it was okay to stay over night, both said it would be fine. There were a couple of other vans staying there too. Great location close to Carmel and Big Sur scenic drive
