Castle Crags State Park, located six miles south of Dunsmuir on I-5, offers swimming and fishing in the Sacramento River, hiking in the back country, and a view of Mount Shasta. There are 76 developed campsites and six environmental campsites. The park features 28 miles of hiking trails, including a 2.7 mile access trail to Castle Crags Wilderness, part of the Shasta-Trinity National Forest. The Pacific Crest Trail also passes through the park. Castle Crags State Park is named for the 6,000-feet tall glacier-polished projecting rocks to which game hikers may climb for a great view of the area including Mount Shasta. Visitors should be aware of how high altitude may affect them.
Overall wonderful hike with fabulous views of Shasta and Castle Crags. We went in early March and hit some snowpack about a half mile from the end. It was packed down and quite slippery, so it didn't seem safe to continue. We had hiking boots but no crampons or axes, so we turned around.
The rocky area after the Wilderness marker was a bit tricky. Sometimes it was hard to see where the designated trail was. I'm a bit nervous about heights, but it wasn't bad for me.
We did the Indian Springs spur. It was very warm here (seemed about 75 F) and a nice place for a snack or lunch. Good views here as well, and there is a water source (but I would filter it).
We went slow and were on the trail for four hours.
This was a perfect short loop. I went around noon and it was shady most of the way and mostly pretty flat. You will see the sign for it (and some other harder trails) near the ranger station. The last cross over the creek is over some rocks but if you get wet you're almost back to the parking lot anyway!

So worth the difficult hike! We clocked 9.5 miles, and we didn't start tracking for about a mile. but we went off the trail a bit here and there. Sooooooo worth it for the amazing views at the top!! Very hot in the last section that climbs straight up the crags. Very hot and very steep.
