Boat Tours. The most popular way to tour Crater Lake itself is on a two-hour ranger-led excursion aboard a 37-passenger launch. The first narrated tour leaves the dock at 9:30 am; the last departs at 3:45 pm. Four of the 10 daily boats stop at Wizard Island, where you can get off and reboard three or six hours later. Two of these trips act as shuttles, with no ranger narration. They're perfect if you just want to get to Wizard Island to hike. The shuttles leave at 8:30 and 11:30 and return to Cleetwood Cove at 12:45 and 3:35 respectively. To get to the dock you must hike down Cleetwood Cove Trail, a strenuous 1.1-mile walk that descends 700 feet in elevation along the way; only those in excellent physical shape should attempt the hike. Bring adequate water with you. Purchase boat-tour tickets at Crater Lake Lodge, at the top of the trail, or through reservations. Restrooms are available at the top and bottom of the trail.
