CES is on the shore of Mexico's largest natural lake (Lake Chapala) and at the foot of the mountain range making up the southwestern boundary of the Mesa Central. Both man-impacted and unimpacted ecosystems abound in this region making it ideal for ecological / environmental instruction. Within walking distance from the Station a variety of habitats can be reached. Ecosystems easily reached from the station include montane coniferous forest, desert scrubland, tropical rain forest, large and small lakes, salt lakes, reservoirs, rivers, marshes and thermal springs. Within a half-day drive, we can reach the alpine forests of the Colima Nevado (> 14,000 ft) and the smoking Colima Volcano or the Pacific Ocean at Barra de Navidad and Autonomous University of Guadalajara's (UAG) marine science / aquaculture laboratory. One-hour drive takes students into the city of Guadalajara. There we have access to the UAG campuses with one of the best herbal and botanical gardens in the country and to the state zoological park.
