The Crescent Lake Lodge is fun to visit because Crescent Lake is just amazing. Quinalt Lake Lodge we stop at every time as well.
There is a short hike near Quinalt Lake Lodge that has the world’s largest tree of some species. It’s pretty amazing just to walk right up to it.
The Hoh Rainforest has some good day hikes. It’s hard to get the full Olympics experience without it.
The Sol Duc area has a natural hot spring pool that you can pay to use if you’re not staying there. That’s a fun change of pace.
It’s a lot of work but if you can hike up to Seven Lakes Basin and back in a day that is world class up there. Everything is in that whole High Divide area.
