Monitor Pass

A travel to the top of Monitor Pass

Monitor Pass is a high mountain pass at an elevation of 2.534m (8,314ft) above the sea level, located in California, in the Sierra Nevada southeast of Lake Tahoe, in USA.

The road to the pass is asphalted. It’s called California State Route 89 (Robert M. Jackson Memorial Highway). It was completed in the early 1950s. Make sure you leave enough time to make plenty of stops along the way. This 18-mile span traverses both Alpine and Mono counties. The pass is named after the silver mining town of Monitor. The road is subject to winter closure due to snow accumulation. Dates of closure vary depending on the weather, but it is generally not open to vehicular traffic between late November and early April.

At the summit there's a gravel road climbing up to Leviathan Peak, at an elevation of 2.438m (8,942ft) above the sea level. There are 2 routes to reach the summit. Starting from Topaz Lake (East), the ascent is 15.11 km long. Over this distance, the elevation gain is 987 meters. The average percentage is 6.5 %. And starting from Markleeville (West), the ascent is 8.88 km long. Over this distance, the elevation gain is 801 meters. The average percentage is 9 %. The grade is steeper on the side going toward US 395 so take is easy going down and be prepared for the tough part of the return climb back to the summit.
