Marine marvels
The multitude and variety of Mexico's marine life are amazing
by PETER GREENBERG
Just about everywhere you go, there are great opportunities to get on, in and under the water, to see and often interact with an amazing variety of Mexico's marine life.
Cancun and Riviera Maya
Whale shark season in Cancun and on the Riviera Maya typically runs from mid-May to mid-September, when the water is warmer. These colourfully spotted creatures grow to more than 12 metres (40 feet) long and can weigh more than 18,000 kilograms (20 tons).
From Riviera Maya, a one-hour boat ride to blue water will get you to the whale shark aggregation, where you can get up close with these gentle giants.
June through early October is nesting season for green turtles and loggerhead turtles. A number of hotels have special interactive programs that allow guests to help protect these turtles; at Moon Palace Cancun, you can participate in the hatching and release of newborn turtles to the sea every September and October. Always call ahead to determine specific schedules.
Los Cabos
Whale-watching season in Cabo ranges from early December to mid-April. That's when about a thousand gray, humpback and orca whales head south from Alaska. There are a number of ways to experience these whales. My tip: Go in the early morning, when the sea is relatively calm, and on a larger boat (instead of a Zodiac) if you're prone to motion sickness.
If you like to snorkel, about 14.5 kilometres from Cabo San Lucas and away from the crowds is Santa Maria Beach. My tip: Arrive around sunrise, when the water in Santa Maria Bay is calmer, and you'll have the entire bay nearly to yourself before the big tour boats arrive. You'll see colourful yellow porkfish, parrotfish, sergeant majors and puffer fish, to name a few.
Puerto Vallarta and Riviera Nayarit
Located in the state of Jalisco, Puerto Vallarta and Banderas Bay offer generally calm waters and a number of special chances to experience sea life. Whale-watching season in Puerto Vallarta is a winter and early spring activity, running from December through March.
Other inhabitants of Banderas Bay include dolphins—bottlenose (year-round) and spinner and rough-toothed dolphins (December to March). A number of tours allow you to get in the water and swim with them.
