This unique region, managed cooperatively by the Bureau of Land Management and National Park Service, is home to lava cave tubes and kipukas, which are islands of vegetated lava completely surrounded by newer flows.
Abundant wildlife, including sage grouse, mourning doves, mule deer and antelope, inhabit the area. Visitors marvel at the scale-like formations of the Blue Dragon lava flow and often hike the sharp and broken "a'a" lava of the Bear Park Kipuka. The area's lava tube caves were inhabited as early as 1200 A.D.
The area is trecherous to hike in, some type of communications device is required. Any fall will result in bruises and cuts because of the sharp lava rocks. There are also deep, open rifts and dangerous caves. Rangers recommend only experienced hikers tackle this terrain.
The Great Rift area, located 45 miles east of Idaho City, is difficult to reach. The roads are unimproved and covered by the sharp lava rocks. Nearly all regions require four-wheel-drive vehicles to navigate the sandy and rocky stretches.
The Snake River Plain surrounds the Great Rift. Hiking can be difficult because the volcanic rocks tend to distort compass readings.
Remember to bring water and food and beware of snakes. No trace camping must be practiced.
This region is very hot during the summer months and inaccessible in winter. The catalytic converter in vehicles can easily ignite a range fire during summer months.
