Well-maintained facilities, not much around it
This San Diego County campground owes one of its stars to the only local business that has WiFi for travelers (my T-Mobile had zero bars, no coverage at all). That business is .25 miles from the campground and goes by names including "the malt shop," "the malt liquor shop", "Oak Shores Store," or "the only place in town with WiFi." It's a small multi-functional burger grill, ice cream store, convenience store, and well-stocked (if your beer tastes run solely to IPA) beer/wine store. The park allows alcohol only up to 20% alcohol content.
The shower and restroom facilities are good, the shower had plenty of hot water, 4 minutes for $.50, longer for more quarters. The campsites would be cramped if you had 3 or more in a row occupied. It's a confusing maze of one-way, one-lane 'streets' that aren't always consistent in their "one-way" and are number sequentially along the one-ways, site numbers only visible from the correct direction, but the signage for turns refers to the order that you'll come upon the sites, not numerically (i.e., "Sites 80-67").
This Lake Morena area has obviously seen its better days and probably not likely to regain the days when the lake was full. I won't be returning, but I did enjoy my three nights there. The ranger staff was helpful and attentive, with regular patrols.
