If you think you've seen and done it all in Cozumel, then you probably haven't experienced two of Dive Paradise's best-kept secrets. The center's Twilight Trip allows you to enjoy some of the world's best reefs away from crowds with a late-afternoon dusk dive followed by a night dive. The Twilight Dive is $70 and includes a snack onboard between dives while watching the sun set over the Yucatan.  The price includes tanks, weights, and belt.

Or sign up for the Cock-a-Doodle Diving excursion, which departs by dawn's early light, so you will be first of the day exploring three reefs — and return to your hotel in time for an afternoon siesta. The Cock-a-Doodle Dive is $98 including 3 tanks, weights, belt, and onboard snack.  You must have a minimum of 50 logged dives to participate. Both trips require a minimum of 4 divers and reservation a minimum of 24 hours in advance.
