Fishing is allowed in the lake, but you may find the experience frustrating—in such a massive body of water, the problem is finding the fish. Try your luck near the Cleetwood Cove boat dock, or take poles on the boat tour and fish off Wizard Island. Rainbow trout and kokanee salmon lurk in Crater Lake's aquamarine depths, and some grow to enormous sizes. You don't need a state fishing license, but to protect the lake's pristine waters, the park service prohibits the use of worms, fish eggs, and even some artificial bait (such as powerbait); check with the visitor center for guidance on permissible bait. Private boats are prohibited on the lake.
