Rim Village is the main area for tourist services in Crater Lake National Park in southern Oregon, United States.

 The National Park Service designed Rim Village to concentrate park services at a location that provided easy access to rim trails and view points.
 Because of the unique rustic architecture of the Rim Village structures and the surrounding park landscape, the area was listed as Rim Village Historic District on the National Register of Historic Places in 1997.
Crater Lake Lodge was built in 1915 to provide overnight accommodations for visitors to Crater Lake National Park in southern Oregon, USA.

Wizard Island is a volcanic cinder cone which forms an island at the west end of Crater Lake in Crater Lake National Park, Oregon.
 The top of the island reaches 6933 ft above sea level, about 755 ft above the average surface of the lake.
 The cone is capped by a volcanic crater about 500 ft wide and 100 ft deep.
 The crater was named the "Witches Cauldron" by William Gladstone Steel in 1885, who also gave Wizard Island its name at the same time.
Munson Valley Historic District is the headquarters and main support area for Crater Lake National Park in southern Oregon.
 The National Park Service chose Munson Valley for the park headquarters because of its central location within the park.

 The district has eighteen contributing buildings, including the Crater Lake Superintendent's Residence which is a U.S. National Historic Landmark and separately listed on the NRHP.
 The district's NRHP listing was decreased in area in 1997.

The Sinnott Memorial Observation Station is a sheltered viewpoint built into the caldera cliff 900 feet above Crater Lake in southern Oregon, United States.
 It is located near the Rim Village Visitor Center in Crater Lake National Park.
 The structure includes a small natural history museum with exhibits that highlight the geologic history of Mount Mazama and the formation of Crater Lake.
 The building was officially dedicated as the Nicholas J. Sinnott Memorial Observation Station and Museum; however, it is commonly known as the Sinnott Memorial Overlook or Sinnott Viewing Area.
 It is architecturally significant because it was the first National Park Service building constructed specifically as a museum and the first structure built in Crater Lake National Park using rustic stone masonry construction.
 It is listed on the National Register of Historic Places as Sinnott Memorial Building No. 67.
