In this episode of the Explore Oregon Podcast, host Zach Urness and outdoors intern Mariah Johnston talk about how to swim, boat and fish in the water of Crater Lake National Park’s for the last time until 2029. Located in southern Oregon, Crater Lake is home to the deepest lake in the United States at 1,949 feet. Beginning next year, the only trail leading to the water will close for a three year construction project. That makes this August and early September the last time you can take a boat tour, swim or fish in the lake until almost the end of the decade. Urness and Johnston discuss how to plan the trip and how to experience the deep, blue water in the state's only national park while you still can.
