Explore Crater Lake National Park with a one-day itinerary to the best viewpoints and trails. Hike down Cleetwood Cove, and bring a swimsuit if you are brave enough to jump in the cold water of our country’s deepest lake. If you are even bolder, try cliff jumping into it. For the best view of Crater Lake, hike up to the Watchman Overlook Tower. The best roadside pullouts are at Vidae Falls and Phantom Ship Overlook. To see more of Crater Lake’s volcanic history, explore the Pinnacles Trail. This is a very family friendly park.
