Note on the data: Closure dates can be renewed or changed annually. No whale-shark sighting record is created because the regulated encounter is snorkelling. Water temperature: Rounded surface planning bands; thermoclines occur. Access: LAP is close to the marina; Los Islotes is roughly two hours by boat depending on vessel and sea conditions.
