This adventure has a variety of interesting features such as the wide open McClellan Meadows, lava tube caves right off of the trail, and a waterfall near the end. The route itself follows excellent, smooth trails under dense forest with minimal underbrush. The trail reaches the lava caves at 8.5 miles. The caves have a much higher ceiling than most lava tubes - standing up is definitely not a problem. Bring a strong headlamp for optimal exploration. The trail continues a gradual descent, occasionally popping out into clear-cuts before paralleling Falls Creek past the waterfall. The last 2 miles are a little steeper than the rest as the trail descends over several switchbacks. A NW Forest Pass is required to park at the trailhead. Leave a car at the lower trailhead or be prepared to ride back to the upper one on a paved forest road.

The Syncline trail network covers some extremely beautiful terrain along and above the Coyote Wall in the Columbia River Gorge. The trails ascend and descend the open slopes and oak savanna mostly at a moderate grade, though some sections are steep. In the spring and early summer, the meadows are bursting with many different species of wildflowers typically found both in the desert and mountain environments. During this time, several creeks with waterfalls flow as well, though like the flowers they usually dry out by mid-summer. Descending via the Crybaby and Little Moab Trails is an exhilarating ride on top of the 500-foot basalt cliffs of Coyote Wall. Views of the gorge and Mt Hood are stunning. Beware of poison oak.
