The clear warm waters of Tonga Island Marine Reserve make it incredibly popular with kayakers and swimmers, and trampers on the coastal track will sometimes pop into the water with a snorkel to cool off.
A thriving local tourist industry supports all the marine activities, and visitors can easily combine land and sea adventures in their holiday. There is also a New Zealand fur seal colony on Tonga Island.
Kayakers will often see little blue penguins along this coast and may occasionally be rewarded with an encounter with a pod of dolphins. Because many local estuaries are also protected, visitors may see some of New Zealand’s rarer shorebirds.
