Activity level

This is an exciting opportunity and a relatively active trip. Good health and stamina plus a sense of adventure and a flexible attitude are essential. There will be days with considerable walking and a couple of busy travel days with early departures. We will travel by modern air-conditioned motor coach on roads ranging from modern highways to unpaved and winding mountain roads in remote locations. In addition, there will be two on tour flights, enabling us to travel more quickly and comfortably to our next destination.

Daily excursions involve one to two miles of walking, often in the full sun in the dry arid climate, and walking tours can last several hours, including periodic stops. Some walking takes place in older quarters, such as in Valparaiso and San Pedro de Atacama, where streets are often cobblestoned and uneven, or on unpaved ground at the numerous natural history sites we will visit. These busy times will be offset by leisurely visits to some of Chile’s wineries, outstanding meals at local restaurants, time to explore the quaint towns and villages on your own, and most importantly, ample time at the observatories. You do not have to participate in all the scheduled activities, except when traveling to the next destination.

Although Santiago is at an elevation of only 1,700 feet above sea level, the majority of the itinerary takes place at higher altitude, with much of the time spent between 7,500 to 8,500 feet.  The response of the human body to altitude is individual and somewhat unpredictable, so personal health concerns must be considered. However, scientists routinely travel to all of the places we will visit with no adverse effects.
