Overview: This is an easy hike to a peak with a perfect view of Jefferson. Make sure to follow the GPS track carefully to find one of the coolest and least known caves in Oregon.

Tips: Directions to Trailhead:
Drive 56 miles east from Salem on Highway 22. Just east of Idanha, turn onto McCoy Creek Road 2233 on the north side of the highway. Follow this 8 or 9 miles until the pavement ends and it becomes gravel. Follow signs for 2233 until about 1.3 miles after a small winter sports building where you pick up Road 635 which leads shortly to the Triangulation Peak trailhead.

A Northwest Forest Pass is required to park here.

Summit of Triangulation Peak

Check out the views of Jefferson. There are two peaks at the top. The true summit is the furthest one from the trail. Pick whichever has less people and relax in the sun for a bit!

Boca Cave

Follow the GPS track closely to find this cave. You'll need to take a small hidden path down a steep slope to find it. It's well worth the effort. See attached photos! It's big!
