Embark on the Dirty Harry's Balcony Trail, a moderate hike that takes you through diverse forest scenery. You will cover 2.2 miles (3.5 km) and gain 1230 feet (375 metres) in elevation, typically completing the route in about 1 hour and 21 minutes. The path gradually steepens as you ascend, leading to the prominent rocky outcrop known as the Balcony, which offers expansive views of the I-90 corridor and surrounding mountains. Along the way, you will find several viewpoints providing glimpses of the valley and impressive peaks like Mount Kent. This trail provides a rewarding outdoor experience for those seeking a challenging yet accessible climb.
When planning your visit, remember that a Washington State Discover Pass is required for parking at the trailhead. Due to the trail's popularity, especially on weekends, arriving early is highly recommended to secure a parking spot. If you plan to hike during winter, be prepared for potential snow and ice; microspikes or ice trekkers may be necessary to ensure safe passage on the trail. Always check current conditions before heading out to make sure you have the right gear.
Located within the Middle Fork Snoqualmie Natural Resources Conservation Area, this trail is a popular choice for hikers near Seattle. It stands out for its significant elevation gain over a relatively short distance, making it an excellent workout with a big payoff. The sweeping vistas from the Balcony, overlooking the I-90 corridor and various mountain peaks, make it a memorable destination. This route offers a fantastic opportunity to immerse yourself in the natural beauty of the region and enjoy impressive panoramic views.

Tips from the Community
The Hall Creek Trestle is a historic steel and timber railway bridge built in 1912. It was once the old Milwaukee Road until, in 1988, a storm washed away a central 171-foot section of the bridge. In the 1990s, Washington State Parks restored the trestle, reconnecting the east and west segments of the former rail line, which is now part of the Palouse to Cascades (Iron Horse) Trail. The views down into Hall Creek Valley are genuinely stunning and worth the ride!

Great views from here. And... the middle of the trestle is different than either end because it had collapsed and was rebuilt in the late 90's

I am always amazed how different this lake looks in the spring (full) versus the fall (almost empty). Those "Seals" are visible in the fall but then go for a long swim in the winter and spring...

The State Park is on the West shore of Lake Easton - very nice campground. An excellent overnight spot in the Spring/Summer/Fall when doing the Palouse to Cascades trail. Worth looping around the lake to see it from all sides and experience the tunnel and bridges. Decent provisions available in town.

Great bridge! You can ride all the way around Lake Easton, over this bridge, under a cool tunnel, past the State Park, and across another bridge that used to be the main highway across the cascades (Highway 10). Very beautiful ride!

This is the last tunnel you will see until (or the first tunnel you have seen since) Thorp. Wooded, along the lake, nice spot to stop.

...and for no particular reason, someone has thought of your needs. This toilet is here, just in case!
