If the campsite is an ADA handicap site, can we still reserve it even though we don't have anyone who is handicapped at the day or the day before? Also, since there is only one camp site available, can we fit 11 people on one site?

No you cant.

I think you need 2 campsites with 11 people. Number of vehicles also important! Call in advance, as much as possible.

I think not. I had eight and that was stretching it.

Call and make reservation. Let them know you have 11.

No they save that for just handicap. Summer time you must call to reserve

Thanks for all your answers!!! Thank you

ADA sites can only be booked without an ADA person in your group right before the camp Rangers close the booth for the night. 8 persons is max for camping but we have had much larger groups for fires and dinner. So if you try and sleep 11 be very respectful of the other campers around you follow the quiet hour rules ect.

Its worth it to experience this part of the California coast...
