Nice spot up on a hill, but this is really a tent camping park. There are no dedicated RV sites except for a parking area which is extremely un-level. $8 fee does not include mandatory daily per person entry fees, unless you have a Texas State Parks Pass. We camped here in a Travel Trailer.
Staying at this park is basically like boondocking. There is no electricity or sewer. There is no water at all in the park. We spent the previous night at the American RV Park behind camping world just a few miles away. We filled up our water tank here. The park is on Trans-Mountain highway only a mile or two off Interstate 10. This was the camping of my childhood. We were the only campers in the park for 3 days. The park is open from 8 am until 5 pm. Once you are checked in the ranger will come by and give you a code. We felt very very safe as there is no way to get around the gate. Our site was fairly level and nestled between 2 hills. We could watch the lights of EL Paso below us and the stars above. The desert mountains prevented any city or highway noise from disturbing our sleep. There is some great hiking in the park & the road good for biking but the trails would be tough on mountain bikers. Franklin Mountain State Park is the largest urban park in the country. There is no shade but picnic tables have shelters. Our 3 nights here was a nice ending to our 3 month stay in El Paso. Would highly recommend if you are just passing through but spend a few days exploring this huge state park. We camped here in a Motorhome.
