Fodor's Expert Review Gemini South Observatory
With one of the largest telescopes in the world, an 8.1-meter (26.5 feet) Cassegrain, this observatory 10 kilometers (6 miles) from Cerro Tololo is operated by a consortium of six nations. Tours are free of charge on Friday mornings and can be tailored to the interests of the group (usually between 10 and 25 people). Email at least a month in advance to request a place on the tour. Priority is given to student and scientific delegations.
