Mount Defiance Trail is a 12 mile out and back trail located near Cascade Locks, Oregon that features a waterfall and is only recommended for very experienced outdoorsmen. The trail is primarily used for hiking and is accessible from May until October.
To find the trailhead you must follow I-84 to exit 55 the Starvation Creek State Park rest area. If you are coming westbound there is no exit and you have to go past to the Cascade locks exit and backtrack. Once at the parking lot the trail begins by taking you along the shoulder of I-84 (behind a fence) for almost a mile before the uphill begins.
The Parking lot is big and there is a restroom at trailhead
