4. Go snorkelling at the Belize Barrier Reef
Going travelling with teenagers abroad doesn't have to be hard work – let them explore the Belize Barrier Reef for themselves. Snorkelling will give you plenty to debrief each other on, from the vibrant reef fish and sea turtles you'll see to safe encounters with nurse sharks and stingrays in Shark Ray Alley.
Groupers and snappers are larger fish species that patrol the reef, and you might spot a Moray Eel peeking out from crevices in the coral. With so much to take in, exploring the second-largest barrier reef in the world tops the list of many holiday ideas for families – especially for holidays with teenagers.
