Take the Portage Glacier Road from the Seward Highway as if going to Whittier. Drive approximately 4 miles to the Williwaw Camp Ground and parking area. If the lot is plowed park there; however, if the parking area isn't plowed be prepared to drive to the Begich, Boggs Visitor Center (another mile down the road) and approach by foot. From the Williwaw parking area find the obvious trailhead beginning at the south side of campground. (Note: The area may be used sometimes by snow machiners so be on the lookout for traffic.) Hike the trail along a well maintained boardwalk until one finds easy passage through the brush to the Middle Glacier drainage. Hike the drainage upstream into the valley. Rainbow Bridge is located at the mouth of the valley on the left side.
