The difference between Heron and other islands is that once there, you have no need to travel farther to the Reef. Step off the beach and you enter magnificent fields of coral that seem to stretch for miles. And the myriad life forms that abound here are accessible to everyone through diving, snorkeling, or reef walks at low tide.
There has been a resort on Heron since 1932, and in 1943 the island became a national park. It is a haven for wildlife and people, and an experience of a lifetime is almost guaranteed at any time of year, particularly if you love turtles -- Heron is a haven for giant green and loggerhead turtles. Resort guests gather on the beach from late November to February to watch the female turtles lay eggs, and from February to mid-April to see the hatched babies scuttle down the sand to the water. Humpback whales also pass through from June through September.
Three days on Heron will give you plenty of time. The island is so small that you can walk around it at a leisurely pace in about half an hour. One of the first things to do is to take advantage of the organized activities that operate several times a day and are designed so guests can plan their own days. Snorkeling and reef walking are major occupations for visitors -- if they're not diving, that is. The island is home to 21 of the world's most stunning dive sites.
Guided walks provide another way to explore the island. Walks include a visit to the island's research station. As for the reef walk, just borrow a pair of sand shoes, a balance pole, and a viewing bucket, and head off with a guide at low tide. The walk can take up to 90 minutes.
