A nice walk through the desert to check out a cool hidden dirt bike track. Google Maps will tell you to go drive down a dirt road (which you can as it's cleared... but not the best of dirt roads) but if you don't have a car that can then go to the parking at the north-western most end of W Camino Racheria and it's a 0.15 mi hike. Good for kids and dogs, just watch out for cactus and ants.
