Anza-Borrego is the largest CA state park and has tons of its own unique features. Mainly for 4WD, offroading, and dirt biking enthusiasts, we still had a lot of fun on foot and with just 2WD. Fish Creek Is just a tiny portion of the park, but the wind caves are truly unique and offer an amazing view for sunset. Hint - if you camp at Fish Creek Primitive Campground nearby, it's free and there are fire rings and a very clean toilet.
