LaCrosse Basin is in the headwaters of the Duckabush River in Olympic National Park. It is one of the most scenic areas, next to the High Divide (and a couple others that shall remain nameless to protect their pristine nature), but due to the multiple day hike necessary to access the area, it is not as crowded as other areas of the park. Depending on your route, it’s typically a 3 day hike in. (Doing it in 2 days is possible if you are very fit and like long days) That said, all the remote areas of the park are seeing increasing pressure from backcountry hikers. I expect that there will come a time where the whole park is subject to a reservation system to keep the fragile high country from being loved to death.
