Rode this trail with a friend on horseback just halfway to "the bench". It was a windy, windy day and we stayed out of it the majority of the ride except for the last 400 yards to the bench. Got off a couple times due to "knee-knocker" boulders, but in general, it's a nice ride. Out and back, with a couple stops for pix and to eat a quick bite was 5 hours at a steady walk. Horses should be relatively fit and used to "rock-climbing".
Take a map and make sure you stay on trail you planned to go on. We took a trail from a trail and got lost for about 3hrs turns out we were on the Pacific Rim Trail heading towards the Spooner Summit. And then had to turn back cause it was never-ending. Trail is definitely not for beginners. Total I think we hiked about 20miles and we only wanted to go on a 1hr long hike. Great hike if you're experienced.
