Olallie Butte is a 7,215-foot shield volcano in Mount Hood National Forest that offers an incredible perspective of the surrounding wilderness areas along with a head-on view of the nearby Mount Jefferson. The trail and switchbacks leading to the summit are not for the faint of heart, but a trip up this peak/volcano is sure to fill your cup.

You can find Boca Cave by taking a short spur trail near the summit of Triangulation Peak. The cave offers some pretty cool views from the entrance and is actually a pretty wide shelter in itself once you start walking through it. If you've already gone up the slopes of Triangulation Peak, this is worth a visit.

At 126 feet tall and 51 feet wide, Henline Falls is one of the main attractions within the Opal Creek Wilderness. The falls are created by a massive cascade along Henline Creek and aren't visited as much as the nearby Three Pools due to its rough trail. If you are looking for some extra miles, the Ogle Mountain Trail keeps on climbing past the waterfall turn-off.

Nearing the summit, the world unfolds. Gaze upon Detroit Lake, and the encircling Rocky Top, Water Tower Mountain, and Mayflower summits. From the peak, the vista extends far, revealing Mount Jefferson, the Three Sisters, and even the distant silhouette of Diamond Peak on the horizon.

Set just off the Rim Trail, 134-foot Winter Falls is one of the longest drops in Silver Falls State Park — but it doesn't always have water. It's typically at its best during the winter, and may sometimes run completely dry in the summer.
