This trail is open to hiker, horse, motorcycle and bicycle use.

Little-known and little visited, Allen Mountain’s allure is its solitude. Deer and other wild critters are prolific on this 5,095-foot mountain. Hikers are not.

A fairly nondescript peak located just south of the precipitous and prominent High Rock, Allen Mountain sees very few boot prints. Hoof and paw prints however, are another story. Located in an oft forgotten corner of the Gifford Pinchot National Forest, much of the surrounding landscape was intensively logged in the past. But, groves of old-growth forest still cover the mountain and its high ridges are carpeted with wildflower meadows. The going can be a little rough-the tread fading in places-but experienced hikers seeking good views, chance wildlife encounters and a backcountry all to themselves will be satisfied.

The Allen Mountain Trail begins at Cougar Gap and travels east to FR 8460. It doesn’t lead to the mountain’s summit-although experienced off-trail travelers can easily bag it-but instead runs along the peak’s south facing slopes. En route the trail traverses sprawling meadows, skirts ledges and makes a few steep drops and ascents. Views are excellent to Mount St Helens and rows of emerald ridges and peaks south; and there are some good views north too, to the Sawtooth Ridge and Mount Rainier.

The eastern approach via FR 8460 can be rough and not recommended for most vehicles. The preferred route is from the west via the Greenwood Lake Trail. Locate this trail across the road from the High Rock Trailhead. It begins on a closed to vehicles spur road taking off south. Hike the old jeep track along an open ridge lined with bear grass. Look back to admire High Rock with its historic lookout. And look northeast at Mount Rainier dominating the landscape.

After about .25 mile the jeep track ends and trail begins. The way descends about 400 feet into old growth forest before crossing a small creek. It then steeply climbs reaching a logging road at the edge of an old cut at Cougar Gap (el. 4,460 feet). Walk on the road a few steps to the left and locate the Allen Mountain Trail marked with a bent post denoting Trail no. 269.

The trail takes off northeast through brushy meadows. Route finding may be a little tricky here, so pay close attention to the tread. Watch for burrows too in the trail, lest you twist an ankle. The way then begins to steeply climb up Allen’s west face via a series of tight switchbacks. The tread is sketchy over rocky sections and through overgrown meadows, but you should be able to follow the way with minimal navigational complications. The trail gets much better so don’t get discouraged. Showy wildflowers and emerging views of Mount St Helens should help ease any frustration along the way.

The grade eventually eases, as the trail now traverses groves of old trees. At about 1.2 miles from Cougar Gap emerge upon sprawling herbaceous flowering meadows. The tread disappears here. Carefully contour across the slope to once again pick up the trail. The way becomes more defined as you continue hiking east. After reaching a highpoint of about 4,825-feet, the trail gently dips and climbs to round a shoulder. It then steeply switchbacks downward passing below some ledges. Pause to take in some good views of Mount Adams and the Goat Rocks.

At about 2.2 miles from Cougar Gap the way enters a grove of towering trees before coming to the edge of an old clear cut. Now traversing the cut, slowly descend to a 4,270-foot gap providing excellent views of lush wetlands below and Mount Rainier towering above in the background. Then begin climbing again to round a knoll (el. 4,590 feet) and skirt some cliffs. From here the trail continues across a brushy slope, but the views out to Rainier and the Sawtooth Ridge warrant hiking across it. At 3.5 miles from Cougar Gap the trail terminates at FR 8450 (el. 4, 470 feet). Turn around and enjoy the views once more. Perhaps on your return now later in the day you may be fortunate to witness some wildlife. The chance of seeing fellow hikers however are pretty slim.

The Allen Mountain Trail sees some use during autumn hunting season, so be sure to don orange. Beyond the small creek crossing on the Greenwood Lake Trail this hike is dry-pack adequate water. Trail receives minimal maintenance, so expect downed trees and brushy sections. FR 84 and FR 8420 were graded in the summer of 2012 and are both in good shape and drivable for passenger cars.

       Going east to west it's a pretty nice and scenic trail except for a bad 10 minute hike a bike half way thru.

       Really isolated. It's definitely a scenic jaunt and not much for quality singletrack such as you will find on Osborne Ridge but worth a trek to see the "countryside" in that area if looking for a longer ride than just Osborne and very ride-able for the most part still. Views of Rainier, Adams, and even Mt St Helens! It is brushy and a very narrow and exposed trail in places. Could use some traffic to help with that!
