Located north of the city of Klamath Falls and northeast of Medford, Crater Lake can be reached from U.S. Route 97 on the east, on the southwest by Highway 62, and on the northwest by Highway 138. Crater Lake and the remnants of Mount Mazama can be seen from Rim Drive, a road that surrounds the caldera, which is the only part within the Crater Lake National Park where vehicles are permitted. The Garfield Peak Trail, which runs east from the Crater Lake Lodge, offers views from above the lake's surface, with Mount Shasta visible southward. Another trail runs for from Rim Drive's eastern edge to Mount Scott, which offers views of central and southern Oregon such as the Three Sisters located north of Mazama and Mount Thielsen, also to the north. The Cleetwood trail leads for down the northern flank of the caldera rim, eventually reaching Cleetwood Cove where boat trips run from late June or early July throughout the summer season to Wizard Island. Wizard Island can be climbed, offering views of Crater Lake.
