Get out and explore on foot! Because the landscape and environment change so radically every 100 miles or so along the byway, hikers love vacationing here and taking in a whole bunch of wildly differing hikes. Walk along beaches on Whidbey Island, through tulip and daffodil fields in the Skagit Valley, along alpine ridge lines in the North Cascades National Park, or simply through some of the most scenic, mountain territory you'll find in the Cascade Mountains of Stevens Pass and the Leavenworth area. There is a LOT of diversity in the type of hikes as well as level of difficulty. Some hikes may be mild, requiring a modest level of fitness and/or technical skill, whereas full-on mountaineering-level expeditions are accessible as well.

If you plan to hike or camp, chances are you’ll need a pass of some kind. We wish it were easier to determine which pass you need, but to be honest, we know it’s still confusing. That said, we’ll try our best to help guide you. Permits 

If you are hiking in areas with snow or during winter season, check the conditions with the Northwest Avalanche Center.

• Hiking is just like most every other activity or sport—there are unwritten rules that when followed, make the experience much more fun for everyone. And likewise, when not followed, can either drive people crazy or in the worst case scenario, be dangerous. Because we’re in the business of inviting folks from all over the world to come and join us on the trail we figure we would be remiss if we didn’t give folks a few pointers. Take a moment to review Hiking Etiquette before you hit the trails!
