  • Trapper Creek Loop, WA
    Trapper Creek Loop, WA Vicinity Location: The trailhead is about 42 miles northeast of Portland, Oregon in the Gifford Pinchot National Forest. Directions: From Portland, Oregon, there are two ways to drive to the trailhead. If you have an extra 30 minutes then make your trip a loop drive. For the loop drive, take I-205 north across the Columbia River. Exit I-205 on Highway 14 east for about 28 miles through the town of Stevenson. For the non-loop option, take I-84 east from Portland and take exit #44 for Cascade Locks. Take the first right turn, just after you go under the Bridge of the Gods. Pay the $2.00 toll, cross the bridge, and turn right onto Highway 14 and drive 2.5 miles to Stevenson. Once you get to Stevenson, drive about 2 more miles east to Wind River Road. Wind River Road is 5.9 miles east of the Bridge of the Gods. Drive on the Wind River Road north for about 13.4 miles until about 0.25 mile past the Carson National Fish Hatchery. Take a left on Mineral Springs Road (Forest Road 3065) and drive for 0.5 mile. Take the first right on Forest Road 5401 and drive about 0.3 mile to the parking area and trailhead. There is an outhouse at the trailhead. A Northwest Forest Park permit is required at the trailhead. Length and Elevation: To Observation Peak: Length 8.6 miles, total ascent 3,446 feet, descent 432 feet. Total: Length 15.1 miles, total ascent 5,362 feet, total descent 5,362 feet.

  • Falls Creek Falls Trailhead Upgrade
    Decision Notice and FONSI Falls Creek Falls Trailhead Upgrade Falls Creek Falls Trailhead Upgrade Decision Notice and Finding of No Significant Impact USDA Forest Service Mt. Adams Ranger District Gifford Pinchot National Forest Skamania County, Washington Sections 20 and 21, T5N, R7E, Willamette Meridian Decision and Reasons for the Decision Background The Falls Creek Falls Trailhead and the adjacent Falls Creek Trailhead are some of the most popular trailheads for day use on the Mt. Adams Ranger District. The trailheads are located at the end of Forest Service Road 3062 and 3062-057. These roads are accessed from the Wind River Highway (Highway 30), about 10 miles north of Stabler, Washington and are located due east of the Trapper Creek Wilderness. In the summer months, parking is inadequate for the heavy use of these trails. Users heading to Falls Creek Falls park along Forest Road 3062-057 causing congestion, damage to roadside vegetation and roadside foot traffic. This mix of foot traffic, moving vehicles and parked cars is a safety concern and is inconvenient for recreational users. With a reconfigured parking area at the Falls Creek Falls Trailhead the safety risk is reduced. Currently, hikers in spring and fall have no access to toilet facilities. Hikers utilize the shrubs at the trailhead causing concentrations of human waste and toilet paper which is as much a sanitation hazard as it is unsightly. In the summer months rental toilet units are purchased by the Forest Service providing simple facilities for the peak season. With a reconfigured parking area, sanitation facilities would be improved with a new vault toilet.
