Quite pleasant route for both riding and sight seeing up to and around Crater Lake NP. Check the weather, it can be cold/foggy/raining/snowing at Crater while sunny just a few miles away. Little traffic early or late in the season, can be crowded during holidays or when school is out. The road around Crater Lake is breathtaking from the western entrance, but gets the road surface gets progressively worse as you ride clockwise around the lake as part of the rim road is closed during the winter months and therefore ends up with more weather damage to the surface. Be sure to take the road to the Pinnacles which has to be seen to be believed!
