Nice easy hike to a stunning 100 foot waterfall on the east side of Mt. Hood. Makes for a very popular winter hike when the basalt amphitheater is coated in frozen ice from waterfall spray.
From the Tamanawas Falls trailhead, head north and cross a wooden bridge over the East Fork Hood River. On the far side of the bridge you will be met with your first trail junction- turn right and follow the trail as it continues north. You will parallel highway 35 for about a 1/2 mile as the trail climbs a small ridge above the river.
The trail will eventually turn west and descend to a second smaller wooden bridge that spans Cold Spring Creek. Cross the bridge and follow the trail as it now winds along the creek. In about 3/4 of a mile the trail will pass a spur trail on the right at the beginning of a large boulder field. When I passed through in February 2018, this junction was marked with a temporary sign and easy to miss. Continue straight past the junction and follow the trail as it winds through the boulder field. From here its only another 1/4 mile of easy hiking until to you arrive at Tamanawas Falls.
