The wife and I did a roadtrip through Oregon a couple years ago, I think the last week of April. Drove east from Portland and camped along the Columbia River a couple nights. We did an awesome hike from Eagle Creek Trailhead with something like 6 waterfalls. Unfortunately some shithead teens shot off fireworks around there and burned the forest down. Then we drove down to Bend, which I highly recommend if you like beer. Excellent breweries and not terribly far from Crater Lake. As far as it being worth it, that time of year you will likely only have access to the area by the lodge, with most of the road around the lake closed due to snow. We went anyway and it was still an incredible sight. We drove for the coast after that and camped near Yachats, which is pretty small and didn't have a ton going on. Still, the drive up the coast is gorgeous and definitely recommend Cannon Beach. Tunnel Falls, Crater Lake, Yaquina Head Lighthouse
