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.

Triangulation Peak reaches up to an elevation of 5,434 feet and offers some of the best views in all of Willamette National Forest. The summit of the mountain is situated in the middle of a bald that is pointed directly towards Mount Jefferson. The trail itself isn't too rugged until the final mile to the summit (which gets pretty dang steep).

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
