Four and a Half Mile Bridge

From Oregon Hikers Field Guide

4 1/2 Mile Bridge on Eagle Creek (Tom Kloster)
4 1/2 Mile Bridge (Steve Hart)
Tenas Falls (Tom Kloster)



4 1/2 Mile Bridge is the second crossing of the creek on the Eagle Creek trail. Despite it's name, it is closer to four miles from the trailhead to this point. Eagle Creek Trailhead was originally at the campground, so in decades past, it was a longer hike. It is a popular rest stop for hikers heading out to Tunnel Falls or points beyond. It crosses a particularly accessible and deep portion of the creek, making it an obvious spot to take a dip on a hot day or to refill your water supply. There are several campsites up and down trail from this location, meaning campers can frequent this spot as a day-use area for both swimming and fishing.

In the Eagle Creek canyon there are waterfalls wherever you look and the area near 4 1/2 Mile Bridge is no exception. About 2/10 of a mile below the bridge, a side creek drops into Eagle Creek as Four Mile Falls. Just above the bridge another side creek forms Tenas Falls.

There is a campsite just beyond (south of) the bridge on the right hand side, with good water access and a great view of Tenas Falls.
