This volcano has lured explorers for decades. Good reason too: The 8.8-miler mixes trails, routefinding, and hand-over-hand scrambling.

Description

Mt.

Thielsen is a stratovolcano like many other Cascade peaks, but unlike most, Thielsen's 9,184-foot summit has been fractured and eroded into a pointy horn of rock--with no crater--that makes for an exciting class 3-4 climb.

It's only 8.8 miles round-trip, but start early: You'll climb 3,700 feet, and the peak's not nicknamed "the lightning rod of the Cascades" for nothing.

You'll also do a bit of routefinding on the way to the summit: The Mt.

Thielsen Trail fades after you cross the Pacific Crest Trail and you'll pick your way up a talus slope by linking cairns.

The last 100-plus feet is a non-technical scramble, but the most cautious hikers pack slings and climbing rope.

On top, enjoy views of Diamond Lake, Mt.

Bailey, and Mt.

Mazama.
