If you head north out of Crater Lake you can turn west on Highway 230 or the West Diamond Lake Highway. The road turns south eventually paralleling the Rogue River. Of course, pine trees abound.
The Rogue River cuts through some narrow chutes near the highway, which make an interesting stop.
Another human interfering with the view.
A bit rough for a kayak.
…and a bit tight.
Further down the road, the river runs underground, or in this case, under rock. This the outlet, which is an old lava tube.
Near the inlet, there are locations in the rock that were created by eddies in the flowing water. This section of the river is covered during high flows only.
You can turn back east onto Highway 62 and re-enter the park at the southern entrance. There is a fire lookout on the northwest rim which you can climb to get a great view.
Just so happens the Pacific Crest Trail goes through the park. Yeah, we did an hour hike. The trail enters the park near the southern entrance, where we noted more female hikers than males on the trail.
