Trail to War Dance Falls (Above the Falls closed to fishing)
This four tenths of a mile hike up rather steep terrain follows the creek, which is a miniature North Inlet Creek in features. Dry fly fishing the pockets and micro-pools will give you ...
US-34 to W Portal Rd to Tonahutu/North Inlet Trailheads. North Inlet Trail is a gem of a trail and fishery from the very start. After a short three-quarter mile hike from the trailhead, the river meets the trail on the right. It's all one can do to not stop and fish the gorgeous flat stream water. For the next mile and a quarter, the trail heads to the north while the stream flows a few hundred yards to the south. This is Summerland Park. For the first three miles fro the trailhead, the trail is relatively flat, gaining only a few hundred feet of altitude as it closely follows North Inlet Creek to Cascade Falls. For the next 2.8miles to the junction of Ptarmigan Creek (Bench Lake outlet) give you plenty of streamside fishing opportunity.
