This solution addresses snorkeler impacts and dissatisfaction in the Mombasa Marine Park and Reserve (MMPR). James Cook University (JCU) and CORDIO delivered interpretive training to the snorkel industry to encourage pro-environmental snorkel behavior, enhance visitor experience and build sustainability. A major output was the creation of a code of conduct created by members of the snorkel industry. Results included more pro-environmental snorkel behaviors and enhanced visitor experience.
