Facility Overview

Cowboy Joe RV Park is an open-air vehicle and recreational accommodation facility located at 81 Sublet Avenue in Diamondville, Wyoming. Nestled in Lincoln County adjacent to the historic town of Kemmerer, the property features a wide-open gravel layout configured to host a broad range of vehicles. Because it is completely open-air without multi-story ceilings, parking garages, or low overhead canopies, there are zero vertical clearance limitations. This makes it an ideal stop for oversized high-profile transport including standard passenger vehicles, lifted 4x4 pickup trucks, commercial vans, toy haulers, fifth wheels, and Class A motorhomes towing utility trailers.

Visitor & Driver Tips

Diamondville sits at an elevation above 6,900 feet, which means winter weather and freeze conditions can arrive early in the autumn and linger well into spring. Drivers visiting during the colder months should ensure their vehicles are prepared for sub-freezing temperatures, including winterized plumbing and antifreeze. If arriving during summer holiday weekends or peak fossil-hunting months, contacting the park in advance is recommended to verify site hookup availability. When navigating to the property using GPS, follow primary approaches from US-30/US-189 directly onto Sublet Avenue to avoid unpaved secondary neighborhood alleyways.
