Dunsmuir sits in the upper Sacramento River canyon in Siskiyou County, and while the town is best known for the river running through its backyard, the lakes within reach add real variety to a fishing trip here. Cedar Lake and Castle Lake are both accessible from the area, along with broader options across the Mt. Shasta region. Castle Lake, despite being listed under surf fishing, is a mountain lake fishery — the designation likely reflects casting technique rather than ocean conditions — and it holds rainbow trout in a steep granite basin at around 5,450 feet elevation. Cedar Lake offers a quieter, more remote lake-fishing experience. The Mt. Shasta area listing opens up additional lake options depending on where you base yourself. Dunsmuir itself is a practical home base: small, no-frills, with easy highway access north toward Mount Shasta city and the lakes beyond. If you are driving up from the Bay Area or Sacramento, you can be fishing by midmorning. Bring layers regardless of the season — temperatures at elevation drop fast once the sun moves behind the ridge.
Both Cedar Lake and Castle Lake are mountain lake fisheries in the Mt. Shasta region, and rainbow trout are the primary target at lakes like these in Siskiyou County. California Department of Fish and Wildlife stocks many high-country lakes in this area seasonally, so checking the CDFW stocking report before your trip will tell you whether a recent plant has gone in.
Late spring through early fall is the most reliable window once snow has cleared the access roads. Castle Lake road typically opens sometime in late spring depending on snowpack, and fishing tends to be most productive in the morning and again in the evening when surface temperatures cool. Midsummer midday fishing at elevation can slow down as the sun gets high.

Yes, a valid California sport fishing license is required for anyone 16 or older. You can purchase one online through the CDFW website before your trip or at local sporting goods stores in the Mount Shasta area. Check the current CDFW regulations booklet for any specific rules on the water body you plan to fish, including bag and size limits.
A light to medium spinning rod in the 6 to 7 foot range handles most mountain lake trout fishing well. Small spinners, PowerBait, and small spoons are standard choices for stocked trout. If you are fishing from shore at Castle Lake, the granite shoreline can be uneven, so wading boots or sturdy footwear help more than waders in most spots.
Castle Lake is located west of Mount Shasta city, which is a short drive north of Dunsmuir on I-5. From Mount Shasta city you take Castle Lake Road up to the lake, which sits at roughly 5,450 feet. The road is paved but narrow in sections, and it can remain closed into late spring after heavy snow years, so confirm road conditions with the Mount Shasta Ranger District before heading up.
