Ample parking is available on-site. Public transport options include the Mountain Line Bus System, with Route 3 serving the vicinity of the observatory entrance.

Historical & Ecological Origin

Founded in 1894 by Percival Lowell, the observatory's primary purpose was astronomical research, particularly the study of Mars. It was built on Mars Hill due to its elevation and clear atmospheric conditions. The observatory is situated within the ponderosa pine forest ecosystem characteristic of the San Francisco Peaks region.

The best months for clear skies are typically September through November and March through May, avoiding the monsoon season and winter snow. Daytime visits offer good opportunities for exploring exhibits and historical structures.

Facts & Legends

Percival Lowell's extensive observations of Mars led him to hypothesize the existence of artificial canals, a theory that captured public imagination but was later disproven. The observatory is also credited with the discovery of Pluto by Clyde Tombaugh in 1930.
