    Directions to Trailhead

    Lake Constance Trail is no small feat. In fact, it’s a huge one, often regarded as the hardest hike in the Olympics. This 23.3 km trail requires 1,493 m of elevation gain, but the devil is in the details—parts of this route are very, very steep and dangerous, and there is little respite from the grind. Some hikers can do it in a (long) day, but most adventurers backpack. Come prepared for the adventure of a lifetime!

    Route Description for Lake Constance Trail

    Lake Constance Trail is regarded as the hardest and steepest hike in Olympic National Park, and as such, we only recommend this trail for experienced, confident hikers. It’s a very full day trip if you intend to finish it without backpacking, so prepare appropriately and give yourself ample time. Watch for ribbons and red markers as you go.

    The initial stretch follows Dosewallips Road along the river, which is gorgeous. When you come to the Elkhorn Campground, stay right at the Y-junction. After a few more miles (about 5 from the trailhead), the trail to Lake Constance is on your right, heading straight up. The big push begins here. It’s relentlessly straight up with np switchbacks to aid your progress. You’ll be climbing with your hands for long stretches and this section lasts for a full two miles, which will likely feel like the longest two miles of your life.

    Pull yourself over the last ridge to the Lake, a purely stunning sight and a very welcome reprieve. If you’re camping, make your home for the night. If you’re headed back before nightfall, prepare for the brutally steep descent and begin to retrace your steps.
