What campers like
Urban convenience: Sweetwater Summit Regional Park combines outdoor access with city proximity. "We had a wonderful stay here! The campground was clean and well maintained.

What you should know
Reservation timing: Popular campgrounds fill quickly, especially during summer and weekends. At Santee Lakes Recreation Preserve, one frustrated camper reported: "I have been trying for 2 1/2 years to get back in, almost every day so we can visit our grandchildren. The thing is if you are not from town or immediate area you can only reserve Monday afternoon to Friday morning!"

Operating hours: Some facilities have restricted access hours. At Silver Strand State Beach, "They lock entrance gate and restrooms around sunset," according to Michael, while another camper noted "They also lock you in the campground at 8 pm."

Tips from RVers
Site selection: At Lake Jennings, Preferred View sites offer more privacy and better vistas. "An added benefit of the Preferred View sites is the privacy since no one is camped behind you. Our particular site even had useful shrubbery on each side to create a quasi sense of privacy between sites," reports Moriah M.
Internet access: Cell service and connectivity vary by location. "Internet service was great for Verizon. We got 23 Mbps with 3 bars of 4G LTE unboosted, and 69 (!!!) Mbps with 5 bars using a simple MIMO antenna. We live and work in our RV (20' Class B) full time, so this was crucial," notes Moriah M. at Lake Jennings.
Hookup availability: Most campgrounds offer various hookup options. "Full hookups. Great pull thru sites on level concrete pads," reports Joni M. about Sweetwater Summit Regional Park, while another visitor mentions "Nice camp ground. Get there early it is busy. Nice showers and water."
Leveling requirements: Some sites need significant adjustment for RVs. Jessica M. observes about Lake Jennings: "Some sites need much leveling. I know which site to reserve next time!!"
