The absolute closest campground you will find in the Hoh Rainforest to the most iconic trails in all the rainforest, the onsite campground is one which truly is a gem in Olympic National Park.

Because of its location prepare for rain!!  I planned a stay here only to find I was basically rained out of my initial site which was slushy and slimy.    On a good day however this campground really shines!!  And when you are preparing if you prepare with an additional tarp you can still comfortably sleep here without issue in a tent.   

I did see the advantage of those who were in hard sides however.  They stay could be much more universal than it is in a tent as there would be no assembly.   Sometimes in this area it can rain for days on end so a tent can pose an issue within those circumstances even with a tarp shelter.    

Personally I would recommend checking the weather for the slightly less rainy season if tent camping based on my own personal experience.    

Overall the facilities were clean and nice and offered standard amenities.   However the restrooms seemed to be heated a bit which was very nice.

My favorite part of this campground however was the proximity to the trails.   At any time you could venture a couple hundred yards and be in the middle of something spectacular.   Green isn't even the color, it is beyond that it is electric.   

You also have a very high chance of an elk sighting in this area is you are quiet, which is beyond words if you enjoy photography.   Just take heed from the visitor center on proper safety measures however.
