We accessed to the trailhead for Thunder Creek Trail from the parking lot of the Colonial Creek Campground along Highway 20 about 24 miles east of the town of Marblemount. Unable to drive all the way into the campground and to the trailhead until the Memorial Day weekend, we parked in a lot just outside of the main camping area and walked maybe a half mile or so through the campgrounds until we reached the trail.
Once on the trail, the sound of Thunder Creek lived up to its name as we passed through the wild and scenic forest.
There were lots of different wildflowers to enjoy along the way.
It’s an easy, well maintained trail with sturdy bridges over all stream crossings with barely more than 650 foot elevation gain over the entire twelve miles roundtrip hike.
