Mailbox Peak Old Trail and Mailbox Peak Trail

Starting your adventure near King County, Washington, the Mailbox Peak Old Trail and Mailbox Peak Trail offer a challenging yet rewarding experience. This loop trail spans approximately 12 kilometers (7.5 miles) with a significant elevation gain of around 1500 meters (4921 feet).

Getting There

To reach the trailhead, you can drive or use public transportation. If driving, head towards the Middle Fork Snoqualmie River Road, where you'll find the parking area near the intersection with SE Middle Fork Road. For those using public transport, the nearest significant landmark is the North Bend Park & Ride. From there, you can take a taxi or rideshare service to the trailhead.

Trail Overview

The trail begins with a steep ascent through dense forest, offering a rigorous workout right from the start. The Old Trail is known for its challenging, unrelenting climb, while the newer Mailbox Peak Trail provides a more gradual ascent with switchbacks. Both trails converge near the summit, allowing you to choose your preferred route up and down.

Key Landmarks and Sections

• Forest Ascent (0-3 km / 0-1.9 miles): The initial section of the trail takes you through a lush forest of Douglas fir and western hemlock. Keep an eye out for wildlife such as black-tailed deer and various bird species.
• Switchbacks (3-6 km / 1.9-3.7 miles): As you continue, the newer trail's switchbacks make the climb more manageable. This section offers occasional viewpoints where you can catch glimpses of the surrounding mountains.
• Boulder Field (6-8 km / 3.7-5 miles): Nearing the summit, you'll encounter a boulder field. This rocky terrain requires careful navigation, so make sure to use HiiKER for accurate trail guidance.
• Summit (8-9 km / 5-5.6 miles): At the summit, you'll find the iconic mailbox, where hikers often leave notes and mementos. The panoramic views of the Cascades and Mount Rainier are breathtaking and well worth the effort.

Historical Significance

The Mailbox Peak area has a rich history tied to the logging industry that once thrived in the region. The trail itself was named after the mailbox placed at the summit by early hikers, which has since become a beloved tradition.

Descent

For the descent, you can either retrace your steps down the Old Trail for a quicker, albeit steeper, return or take the newer trail for a more gradual and scenic route back to the trailhead.

Preparation and Safety

Given the trail's difficulty, it's essential to be well-prepared. Bring plenty of water, snacks, and layers of clothing to adapt to changing weather conditions. Good hiking boots are a must due to the rocky and uneven terrain. Always check the weather forecast before heading out and let someone know your plans.
