This is a San Diego County Park/Campground. It offers everything from tent/car camping to full hook-up for large RVs. The campground also has some nice amenities: good trail system, a splash pad (open in spring and summer months), a playground, some areas to have a group picnic, even a large event room. There are about 60 camping spaces, mostly partial hook-ups (electricity and water) and a few full hook-ups (electricity, water, and sewer) in the original campground. These sites, 1-60 offer a bit more shade than the newer campsites which are all full hook-up. The newer sites (61 and higher) are on a hill and offer some good views of Bonita Valley. 61 and higher all are all full hook-ups - but you can put a tent on 'em.
The campground is freeway close and only a few miles away from grocery stores and restaurants.
This campground has a nice feel. It is a good place to unwind and enjoy a campfire and the whole camping experience. Good place for kids. There are several campsites with horse stalls for the equestrian campers.
Sweetwater is perched near a Freeway/Toll Road (not a terribly busy one) and it is under the San Diego Airport glide path for incoming flights. So yeah, a little more city than some other campgrounds.
At this time sites cost between $26 and $36 (?) per night. That gets yo one motor vehicle. Additional vehicles are $4 per night. There is a $1 pet fee, per pet.
