Interesting park in Oregon State. Oregon has only one national park. Around lake is lot of trails but you do not have to go for special hike to see beauty of crater. Color of water is amazing.
In summer you can drive around lake and in winter open is only North Entrance Road. Rim Drive is closed and you can reach only Rim Village from south. But even in winter this place is enough to see Lake. During summer you will have possibilities to take boat to Wizard Island. Around lake trail is easy and short.
