Arkansas offers 11 scenic byways, camping at more than 30 state parks and year-round conditions for RV travel. The Pig Trail (Ark. 23) is not suitable for large RVs due to tight roads, zero shoulders and overhanging trees. At Buffalo National River, Buffalo Point Campground has electric and water hookups for rigs up to 65 feet, while other NPS campgrounds cap around 35 feet with no hookups. Crater of Diamonds State Park has 47 full-hookup sites. Cell signal is not always reliable in remote areas such as Buffalo National River.
