Coatepeque Lake is considered one of the most beautiful crater lakes in Central America. On its shore there are hotels, restaurants and tourist establishments for practising acquatic sports. In the lake there is also a small island which was a Mayan site of some importance.
Coatepeque Lake can be reached from Santa Ana by an about 75 minutes bus ride, a little less by taxi. If you are not planning to go the lake shore but you are planning to visit the Parque Nacional Los Volcanes you can still enjoy nice panoramic views of the Lake from one of the lookout points on your way to the Parque. The photo attached is taken from one of these points.
