Elwood Pass is a high mountain pass at an elevation of 3.559m (11,676ft) above the sea level located in Rio Grande County, in southwestern Colorado, USA. There are a few water crossings along the way.
Nestled in the San Juan Mountains, within the Rio Grande National Forest, the road to the summit is unpaved. It’s called East Fork Road (FS 667). Starting from Highway 160, the road to the summit is 28.80km (17.9 miles) long. The first 8 miles starts out as a two lane graded gravel road where it leaves the highway and are pretty tame (suitable for most passenger vehicles). Then the next 10 miles are a lot of climbing and a lot of loose big rocks (4x4 high clearance vehicles are recommended as there are multiple water crossings).
The road is impassable in winters. The steep drive will take some skill, some patience, and some tolerance for vertigo. This is a real Jeep road and should be approached with respect. Driving up to the summit is steep, rocky and a real challenge. Ideal time to travel is daylight. Not advised night drive.
The road is narrow and the views are great. When the road is wet it tends to get slick. The drive is beautiful, but can be treacherous running along a high cliff. A minor trail, near the summit, climbs up to Summit Pass, a pass at an elevation of 3.597m (11,801ft) above the sea level.
