An easy hike with fantastic views of Mt. Jefferson and a little know gem of a cave that frames the mountain in the distance.

I bet it's beautiful! Tried to hike this a week ago and it's closed off due to a fire a few months back. If you try to attempt it, you'll only get about a quarter mile in before you're completely blocked. Not worth attempting it until they reopen it. It's a trek to get there too so just wait. Hopefully this will open in the sprig because I bet the views are amazing!

Great hike, pretty easy until the last 0.8 miles when you start some switchbacks. Bushes are overgrown onto the trail wish I would have worn pants. The views we phenomenal!

Great hike. Started at 3 pm on Monday and finished about 7pm. Pretty easy hike until just before the peak then it is an uphill climb but its nothing too crazy. Had my dog with me and she was off leash she did perfectly ok and because there was no one on the trail I let her roam. Getting to the cave was little less than easy because it's not an up kept trail but it is managable. Overall great trail, beautiful scenery, and easy hike.

Got to the trailhead about 8am yesterday. (Saturday) Hiked to the peak first and met a couple of campers who told us how to get to the cave. The trail is pretty moderate and flat until you get to the sign for the peak and loop trail. Stay to the right to get to the peak. Before you get to the peak there's a trafficked trail that goes off to the right. That's how you get to the cave. A little ways up the cave trail there's a small 3 ft part of a broken tree with a pink ribbon. Turn right there and keep going down a steep down hill slope about 1/4 of a mile and it'll loop around to the cave. It's a little hard to find if you don't know where to go but so worth it!

Nice hike. Beautiful view! Went up yesterday, started at 10 am and saw a total of 15 other people on the trail. At the peak we climbed the tallest rock and ate lunch on the top. Amazing view of Jefferson, South Sister, Three Fingered Jack and Hood! The trail to Boca Cave was pointed out to us by another hiker. I'm not sure I would have found it on my own. The cool cave was perfect after the hike up to the peak! Saw a lot of huckleberries setting. I'll definitely return when they ripen.

We had a great hike to the summit and to the cave. Such a perfect day for the hike and there were no other people up there.

Couldn't do this hike again because of the snow blocking the road. Maybe in a few more weeks it will be cleared!

Great hike with amazing views! The Boca cave was a little tricky to get to but well worth it.

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!
