Thanks to Melissa Klurman for spotlighting Sirenian Bay and Placencia in her “52 Mini Vacations That Won’t Break the Bank” at RD.com.

From the article:

The hidden gem of the Caribbean, the Placencia Peninsula is an easy entry into Central America, with turquoise Caribbean waters, access to the second largest barrier reef in the world for snorkeling, rain forest adventures (including ziplining and river tubing), and plenty of family friendly activities. Extra bonus: Since Belize is a former British colony, this is an English-speaking destination.
