An easy hike with fantastic views of Mt. Jefferson and a little know gem of a cave that frames the mountain in the distance.
Great hike phenomenal views. Once near top follow cairns and side trail to caves moderate intensity

A bit hard to find the trailhead but well worth it in the end!
Get trail! The views are amazing. I will say though there wasn't much to look at until you got to the view point
Beautiful trail. Fairly easy too- until you hike down to the caves (which you should definitely do!!). It's very steep and slipper- but it's an incredible view and experience to be in the cave.
Fun hike and beautiful view when you get to the south side of the mountain. Kind of. boring for the first 2.25 miles then it is wonderful. Hard to find the path to Boca Cave so be on the look out.
Beautiful views at the top. It is a little difficult to find the caves, best to print out directions to store in backpack.
Excellent out and back. There's a couple spots to camp near the peak. Get some good photos of the moonrise over Mt Jefferson. Couldn't find the trail to Boca Cave though.
The review with directions starting at McCoy Creek are the best directions. Incredible views at the top, didn't have enough daylight to find the cave but that's on the agenda for next time. Loads of wild huckleberry bushes along the trail. Very easy hike except the last half mile+ which is doable but a bit strenuous on a hot day. Lots of mosquitos and biting flies except at the top; mostly will leave you alone unless you stop moving.
The drive up was pretty gnarly but it's worth it -just don't turn down the wrong road. You won't have cell service up there. There's a parking area at the top near the beginning of the trail. The whole hike is awesome and pretty easy. The beginning is pretty level and full of pungent wild flowers and then you start winding up the mountain. I encountered more than a handful of downed trees on the trail, which were no big deal. Unfortunately I couldn't find the cave. I took the trail up to Triangulation Peak, but it looked like there was another trail. The end of the hike is the peak and the views are amazing. I was able to see some campsites from the peak- maybe this is where the other trail leads? I will definitely be back!
Great hike great view.
Awesome hike! gorgeous view of mount jefferson. If you come from 126, take the alternate route. the GPS tries to take you on NF 302 to get up to the trailhead but that road is not open to vehicles. instead drive past that road and take the next forest road which is nf2233 then turn right onto nf 650 which will take you to the trailhead.
A great hike! Enjoyed this trail and blooming wildflowers along the way. Views at the top were amazing and I felt like I could just reach out & grab Mt Jefferson. Steep down to the cave, but on this very hot day it was well worth the dampness & cool breeze inside the cave.
