Tillie Creek Campground offers 159 family campsites and four group sites on the northeast shore of Lake Isabella, with amenities including flush toilets, potable water, fire rings, picnic tables, a fish cleaning station, and a nearby dump station ($20 fee).

A marina and boat ramps are located just south of the campground, providing direct water access for boating, windsurfing, and fishing.

Sites accommodate RVs and trailers up to 45 feet with no hookups available; reservations are recommended as the campground fills quickly, especially during summer months.
