Mount Pilchuck Hike – The Hardest Trail in Washington?

Mount Pilchuck hike

Hiking Lenght: 5.2 miles

Elevation Gain: 2120 feet

Hiking Time: 3:30 hours

With its mountainous peaks and lush landscapes, the Seattle area has many exciting and beautiful trails to explore. We believe that many of the hiking trails do not require special equipment or skills.

Mount Pilchuck in the Cascade Mountains is one of these trails that are quite beautiful and also quite popular (seeing over 28,000 visitors a year).

Due to its intermediate difficulty level, Mount Pilchuck Hike is definitely not a trail for everyone. But if you feel you can handle the challenge, you’ll be rewarded with 360-degree views that include Mount Rainier, Mount Baker, and the Olympic Mountains.

The starting point for the Mount Pilchuck hike begins at 3100 feet above sea level on forest service land at Mount Pilchuck State Park in Granite Falls.

The park is a 1,903-acre day park with various activities, but the main attraction is the trail that leads up to Mt Pilchuck’s summit.

How to Get to the Starting Point

Once you arrive in Granite Falls, head east on Quarry Road, continue on Quarry Road through the roundabout until you reach Mountain Loop Highway, and turn left there.

Head about 11 miles on that road until you reach Mount Pilchuck Road. Turn right on Mt Pilchuck Road and continue for about 7 miles to the Mount Pilchuck trailhead parking lot.

if you are coming from Seattle, that’s only a 90 minutes drive.

One of the challenging hikes I have attempted so far. Last one mile of the hike is most challenging especially due to knee depth snow. If planning, go with proper gear and the right group of friends.

Mount Pilchuck Trail Description

Mount Pilchuck trail is probably one of the most difficult hikes near Seattle.

Although this trail can get quite busy on the weekends, it does not mean that everyone should attempt it.

It is a steep climb, and during the 2.7-mile hike up to the summit, you will reach over 2,100 feet in elevation and traverse over rocks, boulders, and uneven surfaces.

After taking in the views at the top, you will have to return back down the mountain the same way you came, making the round trip hike approximately 6 miles long. For most people, the hike takes about 4 hours to complete. 


Although you can complete the hike during most of the summer months without any special gear, snow will sometimes remain on the mountains into the early summer months, and you may require proper snow hiking gear and shoes during these times. 

The hike is dog-friendly, but you must keep your dogs on a leash for the entire duration. You may be able to do it with children, but keep in mind that younger children may grow tired or not be able to traverse over the boulders.

One of the main draws of this hike is the old fire lookout constructed in 1918 that sits on the mountain’s summit, which is one of only a handful of these structures remaining in Washington state.

You begin your hike to the summit in an old-growth forest that provides decent cover and shade. It will continue that way for the first couple of miles.

You will know that you are heading in the right direction by watching for the orange markers on the path that are spaced out about every 100 meters or so, but keep in mind that due to the terrain, it can be easy to lose track of the trail if you are not careful.

When you reach the first rocky ridge, look for the orange marker that will direct you over the boulders and help you get to the trail. Here it starts to get more challenging as the trail grows rockier and rocker. 

When you reach the last part of the hike, you must make a final scramble over a long craggy stretch beneath the ridgeline up to the Mount Pilchuck lookout tower.

The tower itself has rocks surrounding it and a ladder you will need to climb to reach the top.

Once you’ve reached the tower and climbed to the top, you will see some fantastic 360-degree views of the surrounding mountains (Mount Rainer, Mount Baker, and the Olympics) and Puget Sound.

Take a few minutes to read the five plaques on the lookout walls, as they tell you the peaks you are viewing and a little bit about the history. Rest for a little while, and then prepare for the descent back down to the parking lot.

Hiking Tips

Although the hike is challenging, it can get quite busy.

If you prefer to hike when crowds are smaller, try to visit first thing in the morning or on a weekday.

Another thing to consider is what to eat before hiking. It’s not an easy hike and you need food that contains lean proteins, healthy fats, and complex carbohydrates.

Because the peak is so high, you will often find snow towards the top well into summer, and the Mount Pilchuck weather can be unpredictable.

Make sure you are prepared for this possibility and wear suitable hiking boots so that you will not slip on the snowy rocks.

Since is a very steep climb, use knee braces for hiking to protect the muscles and the cartilage, and give extra stability.

Use the restroom at the trailhead before you start the hike, and remember to pack ample water for the journey, as it can be pretty tiring, and it is essential to stay hydrated.
