Donaldson Peak stands as the 8th highest peak in Idaho. Named after the late Idaho Supreme Court Justice Charles Russell Donaldson.

Most people climb it in conjunction with Mt Church

The climb represents a 7 mile round trip and 4,400 vertical foot climb.

Nothing in particular stands out about this mountain. It does provide a great view of the other peaks of the range, and the opportunity to climb 2 12ers together.

Getting There

Traditional you start this climb from the base of Jones Creek (Although I personally like to climb the drainage to the Northwest)

To get to Jones Creek from Mackay head 10 miles north on US 95. Turn right and follow the road for 2.1 miles before turning right again. Go .4 miles and then head towards the mountains, where the road will end at the trailhead.

4WD is mandatory for this all other peaks in the Lost River Range (Except Borah)

Red Tape

There are no permits required.
No summit fees
No seasonal closures
No rules for wildlife safety (Besides the general rules you should always adhere to)
No parking pass required
Generally no people

When To Climb

Typically from the middle of June to the end of September. Winter ascents are possible but access is hard and the area is prone to avalanches


There is camping at the base. Very limited water. Hard to find a flat space, but there is no one else.

There is a nice flat spot between Church & Donaldson that is even shaded from the wind. No water access once the snow is gone though.
