I was able to travel frequently and found the bus system in Chile extremely efficient and affordable. Santiago, the capital and largest city, was a popular place for EODP teachers to meet and share their experiences.
Other places I enjoyed visiting in the middle portion of the country were Pichilemu and Valparaiso (both near Santiago), and Valdivia and the Island of Chiloe (further south).
But, if one has the time and resources to do so, the far north (San Pedro de Atacama) and the far south (Torres del Paine) are absolutely stunning. In San Pedro one can bike through the desert, tour the mountains, swim in salt lakes, sand board, and star gaze.
Torres del Paine serves up an epic hiking adventure—be sure to book campsites way in advance! If you are fit and an experienced hiker look into the big circuit, also known as the “O”. I travelled to the far north during my school’s winter break and to the far south after the school year was completed, as these trips necessitated more than 2 or 3 days.
