I fish the River once a year and camp at the Causeway Campground. The camp hostess is very friendly and helpful, the grounds are always clean and well maintained. The other campers are always friendly and courteous, I look forward to returning every year!

Preface: Our review is based on the following lifestyle. We are full-time RVers simply travelling to see the US and not vacationing. We generally spend 3-14 nights in any CG and move on. Our priority in selecting a CG is: America the Beautiful Senior Pass discounts, then Military CGs, City, County, then State Parks. Commercial CGs are our last choice.
General Overview: The route in has easy access. The roads inside the park are wavy; therefore, travel slowly. There are low limbs that scraped our roof. We require a 12’10” clearance. We stayed 4 nights at this park at Site #84 in the River Birch section, 50 amp electric service without water or sewer was available. There are water hydrants in the area where you can fill your tank or tote water from them to your site. No one is permitted to affix and keep their water hose attached. The electric service had no issues. Our site was on a gravel surface with a patio. There were no issues with leveling. Each site has a picnic table and a fire ring. The shower/bathhouse which was clean; however, about ¼ mile back up the entrance road. There is a concrete and brick outhouse in the River Birch Loop. The Loop has 20 campsites. There is a playground for youngsters up through 5 years old in this section of the park. Trash collection is a dumpster located in the vicinity of the beginning of the camping loop. AT&T and Verizon service were both available usually with two to three of four bars. We were able to stream movies with AT&T service via an iPhone 7plus and iPhoneSE hotspots and Verizon Jetpack.
