Centro Mexicano de la Tortuga is the institution that explains Mazunte's modern identity. The town once depended heavily on turtle hunting; after Mexico banned the trade, conservation and small-scale tourism became the new story.
The centre has aquariums, exhibits, and information on the sea turtles found on Mexico's coasts. It is modest, but it gives useful context before you see turtle-release tours advertised along the coast. Check current hours before going, as schedules can change.
