THIS is the trail you want to ride. Starting in sub-alpine wildflowers on rolling single track and ending fast and flowy, this trail has it all. Unlike the MRT, this is a purpose built mtb trail that rides very well. Shuttling to the Horse Pasture trailhead on Olallie and peddling up 50m over 1.5km to the start of O’Leary is the recommended access. Link O’Leary, Castle Rock, King Castle for the full experience. The first 9km of this top to bottom ride has 90% of the climbing; type 1 fun the rest of the way.
There is a creek on Castle Rock to refil water.

For an experienced mtber, O’Leary is actually easier than the MRT. Everything is rideable and there are no mandatory features. The most difficult section is a a series of tight , shale, switchbacks.

 I’d rank the O’Leary, Castle Rock, King Castle ride in my top 5 rides of all time. Coming from North Vancouver, this is what I was looking for in Oregon: beautiful sub-alpine wildflowers and views into loamy flow amidst huge trees. If these trails were in BC they would be blues with a couple tight switchbacks.
Completely different than the McKenzie River Trail and way more of a true mtb ride. Purpose built for mtbing and no mandatory features.
