Beautiful get-away! This is certainly a wonderful break from the city at a mountainous location, close to San Diego. You don't need a 4x4 to get up the dirt/gravel road.
Tom and Stacy were very hospitable. They left plenty of firewood for the fire pit, snacks and water, towels/washclothes, paper towels and toilet paper, board games, wifi, tv, soap, dishes, plus plenty of extra bedding and sleeping bags, trash bags. The area is fenced in but we warned of poison oak/ivy if we ventured far from the paths and mowed areas. There really aren't hiking trails leading directly from the glamping area, except there a wonderful steep dirt road we walked up many times which rewards an amazing view. Make sure to test the hot water heater beforehand. Also, the water is supplied from an on-site spring well so it's wonderful and plentiful.
The only things we would bring to stay again would be binoculars (many birds to see), aluminum foil plus cooking oil to make cooking/warming food on the fire pit easier (there is also a propane grill outside. We did forget our dog's throwing stick but found the area small enough to just throw the ball and let is roll down the steep hill (our labrador absolutely loved staying here and Tom and Stacy were very friendly to her staying as well).
