The Big Three Washington Passes

Almost every trailhead in Washington falls under one of three jurisdictions: State, Forest Service, or National Park. Each has its own dedicated pass.

1. The Discover Pass (State Lands)

The Discover Pass is for Washington State recreation lands. If the trailhead is managed by Washington State Parks, the Department of Natural Resources (DNR), or the Washington Department of Fish and Wildlife (WDFW), this is the pass you need.

Cost: $30 annual pass, or $10 for a single day (plus transaction fees if bought online or at a store, bringing it closer to $35/$11.50).
Hikes that require it: Mount Si, West Tiger 3, Wallace Falls, and Dirty Harry’s Balcony.
Key details: The physical annual pass has spaces for two vehicle license plates, so you can share it between two cars. However, you can only use it on one vehicle at a time. It must be clearly displayed on your dashboard or rearview mirror.

Many of the trails that require this pass are excellent after-work options because they are close to the I-90 corridor (so in other words state parks!). Moving from sedentary work to rapidly hiking up a mountain can feel quite intense, but catching a golden hour sunset makes it totally worth it, even if it means a late night for a workday. For example, you can read my first-hand Dirty Harry’s Balcony hike report to see how my friends and I did a late Wednesday evening trek there. And if you make it back to town in time, check out my guide to the best Seattle happy hours in Capitol Hill and the Central District to celebrate.

2. The Northwest Forest Pass (National Forests)

The Northwest Forest Pass is a federal pass specifically for USDA Forest Service recreation sites in Washington and Oregon. If you are hiking in the Cascades or the Olympics outside of the National Parks, you are almost certainly on Forest Service land.

Cost: $30 annual pass, or $5 for a single day.
Hikes that require it: Bridal Veil Falls, Granite Mountain, and Talapus & Olallie Lakes.
Key details: This is a vehicle-based pass. If you have the annual version, it covers parking at all Forest Service trailheads in the PNW.

Many of these trailheads lie along the Scenic Highway 2 corridor or deep in the Snohomish County mountain loops. If you are heading out early to hike Bridal Veil Falls or Lake Serene, note that there is a fun Espresso Chalet near Highway 2 that is a great place to stop before or after an early morning hike.

3. The America the Beautiful Pass (National Parks & Federal Lands)

If you plan to visit a National Park (like Mount Rainier or Olympic National Park) or hike frequently in National Forests, the America the Beautiful Interagency Pass is the best investment you can make.

Cost: $80 annual pass.
Lands covered: All National Parks (Rainier, Olympic, North Cascades) and all federal recreation sites (including National Forests).
Key details: This pass completely covers and replaces the Northwest Forest Pass. If you hang this from your rearview mirror, you are good to park at any National Forest trailhead and enter any National Park for a full year.

Note: It does NOT cover state lands, so you still need a Discover Pass for state parks.

Where Can You Hike for Free?

Not every trailhead requires you to pay for parking. Some hikes sit on city, county, or utility lands that do not enforce pass requirements.

Rattlesnake Ledge: The land is managed by Seattle Public Utilities, and parking at the main lot is completely free.
Twin Falls: The trailhead sits in a state park boundary but has a designated free parking zone (always check the signs at the trailhead to be safe).
Little Si: While it sits in the Mount Si NRCA (DNR land), there are occasionally free overflow parking options if you park in designated county areas.

Passes vs. Permits: Don’t Confuse the Two

It is important to remember that a parking pass is not the same thing as a wilderness permit.

A pass allows you to park your car at the trailhead. A permit allows you to camp overnight or climb in restricted areas. For example, if you are doing a day hike to Colchuck Lake, you only need a Northwest Forest Pass to park your car. But if you want to backpack and camp overnight in The Enchantments, you must win a highly competitive overnight permit in the annual lottery.

Always check the Washington Trails Association (WTA) page for your specific hike before you head out to confirm both parking passes and overnight permit requirements.

Happy hiking, and make sure to display that pass on your dashboard! huzzah 🙂
