Rappelling and climbing at Multnomah Falls is forbidden. Above the main falls there is a scenic canyon with several waterfalls. This is a popular and fairly well traveled area. All of the falls are plainly visible to hikers. It is essential that no webbing or hangers be left behind. Rappels should be done with retrievable anchors, or removed afterwards.
Hike the paved trail 1.1 miles to the junction above Multnomah Falls. Turn left and follow the Larch Mountain Trail across a small bridge. The trail closely follows the right side of the creek looking upstream. You will pass by three small falls spread a few hundred yards apart. They range from 8 to 15 feet. At one point the trail passes directly beneath an overhanging rock ceiling in an especially beautiful setting. As the trail comes in sight of 60 foot Weisendanger Falls it switchbacks up the side of the canyon until it is above the creek. After the trail passes above 60 foot Ecola Falls (about 1.6 miles from the bottom) find a way down to the creek.
Ecola falls can be rappelled by anchoring from a tree on the right. A retrievable anchor works very well here. Shortly downstream is Weisendanger Falls. There is no good anchor close to the lip of the waterfall. A large tree on the left about 20 feet back from the lip provides an anchor. At the bottom of the falls there is small cave on the right. If you continue down stream you will encounter several small falls. These can be downclimbed when the water level is low, or if you prefer, leave the creek and follow the trail down.
Allow 3 to 4 hours. Take 180 feet of rope, 50 feet of webbing, wetsuit and helmet.
