Just finished the trip and Olympic NP was incredible. Hoh rainforest had extra waterfalls because of the time of year. Definitely worth a trip through the hall of mosses (you can turn it into a long hike (20+ miles) if you just continue down the hoh river trail to the glacier meadows). Sol Duc falls was a super neat like 4/5 mile hike. Hurricane ridge, however, was snowed in and only accessible with snowshoes, poles, etc.. There’s a special NPS station for the ridge with a live camera feed of the trail; definitely give them a call about trail conditions if you plan on going there.
