With a series of more than 2,900 individual reefs that stretch across 1,500 miles, there’s plenty of space for families to spread out and enjoy the fascinating ecosystem of the Great Barrier Reef off the coast of Australia. If your children aren’t old enough to scuba dive, a vacation to the Great Barrier Reef is still incredibly kid-friendly. Tour the reefs with some of the world’s best marine biologists, explore underwater viewing platforms or even helicopter over the reef for a truly unique vantage point — and it really is an underwater paradise for those who do enjoy scuba diving and snorkeling. All that activity will leave families ready for a good night’s sleep. There are almost as many kid-friendly accommodation options near the Great Barrier Reef as there are underwater species, including luxury resorts situated directly above it…no long boat journey needed!
