Happy Hollow Shelter is located 26.3 miles (42.3 km) from the Whiskey Bend trailhead of the Elwha River trail (it is the last shelter along the Elwha trail). You can see from the overgrown condition of the trail that this area of the Olympic National Park doesn’t get a lot of traffic. The shelters are provided for emergency use only … and one should expect to share any shelter in the Olympics with a large population of mice.
Below is the Happy Hollow outhouse. I don’t think I need to provide any additional comments, except maybe privacy is not guaranteed.

It seems those responsible the cabin need to do some repairs!
That would be the National Park.
They don’t do that no more, sadly.
Maintenance and repair of shelters is all volunteer, when the park will allow it.
I see, thanks for this. It’s sad too.
