Campgrounds and RV parks near Twin Falls, ID

Shoshone Falls Park offers playgrounds, hiking trails, picnic areas, a boat ramp, a swimming area, and a scenic overlook. The Snake River Canyon Rim Trail lets visitors walk or bike along the canyon edge with continuous views. The Perrine Bridge, spanning the canyon at the north edge of town, is one of the few U.S. bridges where BASE jumping is legal year-round and draws spectators daily. Dierkes Lake, within Shoshone Falls Park, is a spring-fed lake in a basalt basin with a designated swim area and small beach. Nearby is the earthen ramp site where Evel Knievel attempted to launch himself over the Snake River in a steam-powered skycycle in 1974. Day trips reach the Sawtooth Mountains and Sun Valley to the north, Craters of the Moon National Monument to the northeast, and Thousand Springs State Park to the west.

Spring is the headline season. April is the most consistent month for high water at Shoshone Falls, when Rocky Mountain snowmelt pushes the Snake River toward its seasonal peak. In a typical spring, flows over the falls run between 10,000 and 12,000 cubic feet per second, and in exceptional years can exceed 20,000. Expect busy weekends at overlooks and parking that fills quickly at Shoshone Falls Park during this window. Summer brings hot, dry days and the region's warmest camping weather, but the falls change character. Water levels drop as the Snake River is diverted upstream for irrigation of nearly two million acres of farmland, and the falls can look dramatically different from their spring peak. July and August are the driest months and the busiest for private RV parks. Fall is quieter with cooler nights and thinner crowds; the falls often show minimal flow by autumn. Shoshone Falls Park hours run from dawn to dusk. Winter is the slowest season, with cold temperatures, light snow, and possible temporary closures on the canyon-rim road after storms.

The terrain is flat sagebrush plateau cut by the deep Snake River Canyon. Roads into town are wide and easy for larger rigs, but the descent into the canyon at Shoshone Falls is a paved series of switchbacks that is narrow in places, so larger rigs should use caution on the turns. Summer days are hot and dry with cool nights typical of high desert; bring shade, water, and sun protection. Thunderstorms are occasional on summer afternoons. Winter driving can involve ice and wind on I-84 and US-93. From March through fall, Shoshone Falls Park charges a per-vehicle entry fee that also covers Dierkes Lake, with the fee waived in winter. An Idaho fishing license is required for Dierkes Lake and area waters. Leashed dogs are welcome at most parks and along canyon-rim trails.
