What are the tallest mountains in Oregon

These are the tallest mountain peaks in Oregon

Oregon's tallest mountain rises over 11,000 feet.

The state can boast some of the most beautiful rivers in the United States, the deepest lake in the country, and one of the most complete fossil beds on the planet among its stunning natural features.

And above all this beauty there are some majestic mountains. With the Cascade Mountain Range and Wallowa Mountains calling Beaver State home, there are some fairly tall peaks to climb or just marvel at. These are the 10 tallest mountain peaks in Oregon. (Spoiler warning: Mt.Bachelor doesn't even make the cut!)

Mount Hood

At 11,249 ft, the potentially active stratovolcano is the tallest mountain in Oregon and one of the tallest in the entire country, its prominence. In winter, Hood Meadows is one of the premier snow sports destinations in the Pacific Northwest, while in summer, hikers and campers enjoy the vibrant beauty of Mt. Hood National Forest. Cascade Range Mountain is home to 11 active glaciers and attracts more than 10,000 climbers annually, making its summit the most-visited snow-capped peak in America.

Mount Jefferson

Mount Jefferson is also part of the Cascade Range and is a stratovolcano and the second tallest peak in Oregon at 10,497 ft. Its harsh environment makes it one of the hardest volcanoes in the Cascades; However, its remote location does not hinder tourism. Visitors can hike, hike, climb, and take photos all year round.

South sister

Oregon's four tallest peaks are all located in the mighty Cascade Mountain Range, and third is South Sister. Also known as "Charity", the volcano is the largest of the trio called Three Sisters in central Oregon and only slightly shorter than Mount Jefferson, at 10,363 ft. South Sister last erupted 2,000 years ago and is a predominantly rhyolitic stratovolcano. Unlike its sisters, Charity has an undeveloped summit crater that houses a small crater lake known as the Teardrop Pool - the highest lake in Oregon. It's also the easiest of the three peaks to climb, and one of the most popular mountains in the state.

North sister

North Sister is only slightly smaller than South Sister, measuring 10,090 feet. Also known as "Faith", she is the oldest and most eroded of the Three Sisters. Due to its age and conditions, North Sister is the most dangerous of the three peaks to be climbed and is often referred to as "The Beast of the Cascades". However, one of its peaks, Little Brother, can be confused for sure.

Sacajawea Peak

At 9,843 ft, Sacajawea Peak is the highest point in the Wallowa Mountains in eastern Oregon and the fifth highest in Oregon. It is also one of the most prominent peaks in the continental United States, ranking 18th, and the second most common in the state after Mount Hood. For the curious mountaineer, the easiest route to the Sacajawea summit is via its east ridge from Thorp Creek Meadows. It can also be reached from the Matterhorn via the ridge, although this route is only suitable for climbers.

Steens Mountain

Located in southeast Oregon, Steens Mountain is the only peak on this list that is not part of a mountain range. Measured at an altitude of 9,738 ft, the fault block is the sixth highest peak in the state. Steens Mountain stretches for about 50 miles from north to south and is often mistaken for a range, although it is a unique entity. The mountain is traversed by a 52 mile long bypass road suitable for passenger vehicles and up to 9,700 feet high, making it the highest road in Oregon. Aside from the typical recreational activities (hiking, biking, camping), there are numerous hot springs along the base of the mountain, including Alvord Hot Springs, and its remoteness makes for spectacular stargazing.

Aneroid Mountain

Aneroid Mountain is the second highest peak in the Wallowa Mountains and the seventh in this state. It is located in the Eagle Cap Wilderness of the Wallowa National Forest, just 15 miles south of the Oregon town of Joseph. The climb is pretty easy, but for those who want to make it a challenge, try coming from the south and climbing one of the basalt cliffs. Upon reaching the summit, the climbers are rewarded with a wide view of the Wallowas, further east to the Hells Canyon and north to the Blue Mountains.

Twin peaks

Twin Peaks is not to be confused with the iconic classic TV show, another highlight of the Wallowa Mountains. At 9,609 feet in length, it's just a tad smaller than Aneroid, making it the eighth highest peak in Oregon and the third highest in the Wallowas.

Red Mountain

Just before Twin Peaks and Aneroid's Height, Red Mountain sits 9,537 feet and is the fourth highest peak in the Wallowa Mountains and the ninth highest in Oregon.

Mount McLoughlin

The top 10 round off Mount McLoughlin. Part of the Cascade Mountain Range, this steeply sloping stratovolcano is the fifth highest peak in the Cascades and the 10th highest peak in Oregon at 9,493 ft. Mount McLoughlin is a prominent landmark in the Rogue River Valley and northeast of Crater Lake.

It has enjoyed a handful of different monikers over the years including Mount Pitt, Mal-sr, Alwilamchaldis, Makayax, Walum, Kesh yainatat, Melaiski, and Mount Sastiše to name a few.

But whatever you want to call it, this mountain is great for hiking and skiing.
