Now is the time to get up to the cave before it closes for the summer! This is an easy hike and you'll be surprised when you find out you don't have to get to the peak to reach it. Well there goes the surprise. Once you're at the base of the rock that leads to the cave, it is a lot easier going up but coming down is tricky... Oval Trail Stickers

Great hike... 2 hours if you're in decent shape. The scramble at the top is a little tricky, but was done by 3 people mildly afraid of heights and with limited climbing skills. I saw several dogs and a few little kids do it while we were there. The views are great, the scramble at the end provides a nice little final challenge to get to the cave, and it's a great distance for an afternoon hike. We'll be back and we'll bring friends...

Not a bad workout for a two hour hike. This would be considered easy except there aren't many flat spots. The trail rises fairly steadily. Kind of disappointed with the view since the cave was closed and the trail didn't end at a peak or summit. Three stars as I wouldn't hike this again, even when the cave is open.

This is a decent hike if you would like to get out and spend a few hours in the mountains. The cave is closed until October, but the hike ends in a nice place for lunch or minor (rope free) rock climbing. I would rate it relatively easy with the exception of a few steep sections. Enjoyable for the day - definitely, but not necessarily a repeater.

My friend and I did this today, WHOO was that fun, quite tiring though...we lost the trail after a bit so be careful about that. AWESOME climbing in that area...I am SO jealous of all the people I saw climbing. But I got my chance at the Mallory Cave slab. It wasn't too bad (although I was a pansy and wore my rock climbing shoes) my friend had a difficult time getting up through the first part of the slab which is a small crevasse that might not be to "big people" friendly...its really steep, and rather hard to do (I am scaring you on purpose so when you get up there your gonna be like this isn't bad at all! Leave you packs at the bottom though...pain in the butt to haul those up
