What mountains are in Washington? Which are the tallest, and which are beginner friendly?

Washington has a little of everything when it comes to experienced and beginner mountaineering, scrambling, and hiking (or just sightseeing if climbing mountains isn't your thing!). Here are a few of the most important mountains in Washington:

Tallest Washington and Oregon Mountains

Mount Rainier (Tahoma)

Location: Pierce and Lewis Counties

Height: 14,417'

Mount Rainier
Mount Rainier is undoubtedly the king of Washington's mountains

Rising to an incredible 14,417 ft, Rainier can be seen throughout the Pacific Northwest and is on the "to-do" list of mountaineers worldwide. It's certainly one of the most important mountains in Washington and in the whole of the Pacific Northwest.

Mount Rainier in Washington is a stratovolcano located around 59 miles from Seattle. The mountain also boasts 26 major glaciers and two volcanic craters.

Today the mountain is considered one of the most dangerous volcanoes in the world!

Did you know? Mount Rainier also features on Traverse the Pacific Northwest's 10 of the Best Mountains to Climb in the Pacific Northwest.

Mountains of the World

Mount St. Helens (Loowit)

Location: Skamania County

Height: 8,363'

Mt. St. Helens
The stunning Mt. St. Helens

Who doesn't know about Mt. St. Helens?! This unforgettable mountain is high on everyone's list of notable mountains in Washington. The mountain permanently (and very violently!) marked itself into the history books after erupting on May 18th, 1980.

The terrifying and mesmerizing event killed fifty-seven people and destroyed around 200 homes. Debris from the eruption can still be seen around the mountain's barren slopes.

Throughout the year, you'll see climbers make their way to the summit of the mountain but climbs in the summer are far more popular. So much so that there is a permit system in place to prevent the mountain from becoming overrun with hikers.

Did you know? You can ski down Mount St. Helens in the winter!

Mount Adams (Pahto)

Location: Gifford Pinchot National Forest, Washington

Height: 12,281'

Mt. Adams
Mt. Adams looms in the distance.

Mount Adams is the 2nd tallest mountain in Washington and is notorious among mountaineers for being a long, sluggish climb up never-ending snow. But that doesn't impact its overwhelming beauty and near-constant presence on the Washington skyline. If you've ever visited the border of Washington and Oregon, you'll know its silhouette (and that of Mount St. Helens!) very well.

It is one of the least technical mountain climbs in the state. That being said, no one should come to Adams thinking it's going to be a walk in the park. Crampons, an ice ax, and a helmet are necessary throughout the year.

Mount Baker (Koma Kulshan)

Location: Whatcom County, Washington

Height: 10,786 ft

Mount Baker
Mount Baker is hard to miss in northern Washington

Also known as "P-kowitz," meaning "White Mountain," Mount Baker is one of the crown jewels of the North Cascade Mountain Range. The active stratovolcano is located around 30 miles from Bellingham. It is heavily covered in glaciers, second only to Mount Rainier.

Like the mountains on the Oregon border, Mt. Baker is very hard to miss if you're in northern Washington (or throughout much of the state, for that matter!) Its enormous flanks make it very obvious among the skinnier peaks of the North Cascades.

If you're looking for your first technical mountain climb in Washington, Baker is a surprisingly great place to start.
