Just under a mile in the sky, Whetstone Mountain reaches up to an elevation of 4,969 feet. There are open views from the summit, which is a worthwhile reward for climbing the steep forest path. The summit can be nabbed by taking a short spur trail off the main Whetstone Mountain Trail at the highest point along the ridge.

Henline Mountain offers stunning views all the way up the trail. Take note that there are two 'summits'. About halfway up, there is a false summit that many people stop at for the amazing overlook of the mountains. If you stay to the left, that trail will take you up to the real summit. Due to wildfires back in 2021, the area is currently closed, so check for updates before making the trek. https://www.fs.usda.gov/Internet/FSE_DOCUMENTS/fseprd950391.pdf

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.
