CAMPER SUMMARY PRESENTED BYFord

Justin's Diamond J RV Park, near Tucson, Arizona, is a solid choice for those looking to settle in for a while. This place is busy, and the staff is dedicated to helping travelers find their spots, even if it means moving around a bit during your stay.

The park is clean and well-kept, with spacious sites that cater to RVs, tents, and cabins. Visitors have enjoyed the walking trails that lead directly to Saguaro National Park, where you can soak in the stunning desert landscape and unique flora. As one camper noted, “The area around the RV Park is rich with the native plants of the area all on its own.”

While the park has some restrictions, like no alcohol and no pets, it does offer full hookups and a few recreational options like pickleball and bocce ball. Some guests mentioned the lack of shade from the desert trees, but the night sky views are a highlight, making it a great spot for stargazing.

If you're planning to visit, keep in mind that cash or checks are the only accepted forms of payment, and online reservations aren't available. Just a heads-up: the common areas could use a little TLC, but the overall vibe is friendly and welcoming. Whether you're here for a quick visit or a longer stay, Justin's Diamond J RV Park has its own charm that many campers appreciate.

The Nicest People

I love Tucson. The big plus about this park (other than the really nice people) is that is borders park land and there are SO many acres and miles of trails right out of the campground. The grounds and the surrounding desert have an abundance of interesting succulents and cacti and gorgeous mountains all around. Most of the folks here are long termers- we only stayed for 4 days. The sites for short termers are by the road and not the best, just gravel sites with full hookups, but sufficient for our needs. No picnic tables. No public toilets. Laundry facilities and a gathering room.

Nice clean quiet well kept RV Park

We stayed there for a week in February 2022 visiting family and friends, and exploring the attractions of the area.

Justin’s is a busy place and office staff were almost always on the phone trying to arrange nights of availability or help the travelers any way that they could. When we called they could accommodate us but we ended up in 3 different spots over our week’s stay as there were reservations for the spots that they needed to honor. For us it wasn’t a big deal as we were in a 31’ Minihome. When no space was available I overheard them offering free dry camping until a spot opened up. The business has a very capable and customer focused staff.

The RV Park is clean and capably run. We really enjoyed our stay there and we would return again.

An interesting feature of the Park is that it has walking trails that lead to the Saguaro National Park, but the area around the RV Park is rich with the native plants of the area all on its own. If you travel through Tucson, Saguaro National Park’s Desert Museum is a recommended place to go.

Rather disorganized

Sites are not well defined but once you know where to park the sites are quite large. No real shade is available as the trees are desert spindly. There has been no one in the office and we were told to just park anywhere.

Have to pay cash or check

Justin's Diamond J doesn't allow credit card payment and doesn't have online reservations. It's adult only and had a bunch of restrictions. No use of washers/dryers in RVs, no streaming/skyping, no electric heaters. Breed restrictions on pets. See photo for brochure. There are pickleball/tennis courts, a dog area, horse shoes and bocce ball. Sites are full hookup. Premium sites offer better views and have more privacy.

Great Sky Views

Great views of the sky at night and very quiet but we were never able to get in touch with anyone from the office. Nice spacious sites but the common areas really need some love. There’s no pool which is a must have in Arizona’s heat. Great Verizon cell signal no WiFi, or could never get in touch with anyone to get a code.
