Umpqua National Forest, Oregon
It was quite something to drive through the very smoky part of the Umpqua National Forest being escorted by a pilot car (with signs saying: Active Wildfires, DO NOT STOP). It was hard to get accurate information online about the air condition (it changed fast and the sites were not up to date) and we thought we could camp near the Umpqua River Trail and bike part of it (it's an epic trail), but most of the campgrounds were closed because of the fires. We came across this little gem of a campground just as we were starting to feel a bit discouraged. The air was so cool and fresh by the falls! Oregon is full of incredible places.
We ended up staying there 2 nights and except for a few people driving in to see the falls, stay 10 minutes and leave, we had the whole place to ourselves. We had hoped to go to the Umpqua Hot Springs, but the access road was closed and it was cooking hot anyways.
