There are outstanding locations for snorkeling or diving. Some are even close to the shore and not a boat necessary. Share special places you know and describe what to expect.
Snorkeling during high tide only! Please avoid low tide to protect the corals. At low tide the water level is too shallow and you may destroy corals while you are snorkeling. Check the tide times either at Milyering Visitor Centre or follow the link. Tide Times Exmouth

SNORKELING: The best time for snorkeling is in the morning with calm sea. Towards the afternoon the sea becomes rough. WEATHER: The best climate is during the dry season (from November until April). May and June is worth a try. Avoid July until October, it's rainy season and there is a higher chance for hurricanes. TOURIST CROWDS: July and August are the Cuban summer holiday and it might get crowded in general. Usually Playa Larga itself isn't that crowded at all. There are casa particulares only, not even one big hotel.
