13 Most Beautiful Coral Reefs for Diving, Snorkeling & Adventure

Snorkeling or diving a coral reef is an experience like no other—and between the weightlessness and otherworldly landscapes and animals, it’s like being on a wholly different planet. And just like traveling around dry land, each reef has its distinct features and characteristics, from the Great Barrier Reef in Australia to the Red Sea in Egypt, and beyond.

Let’s have a look at 13 different reefs you can see yourself—whether on a snorkeling tour, a diving adventure, a cruise, or a quick jaunt!

1. The Great Barrier Reef, Australia

Located along the coast of Queensland, Australia lies the Great Barrier Reef—a natural wonder that spans an area larger than the United Kingdom and is home to thousands of species of marine life. The waters are filled with bright coral and tropical fish, sea turtles, dolphins, and even humpback whales.

It is the most extensive coral reef system in the world and a UNESCO World Heritage Site. The reef is comprised of thousands of coral cays and a labyrinth of lagoons, channels, and coral gardens. Visitors can experience the reef’s beauty through snorkeling, diving, or even taking a scenic flight overhead.

2. The Red Sea, Egypt

The Red Sea hosts an underwater paradise in the northeastern part of Africa: schools of colorful fish, sea turtles, and dolphins are just a few of the many species that call this area home. The sea is relatively narrow and deep, with steep walls and canyons providing a perfect habitat for its 1,000 species of fish and 200 species of coral.

The warm, clear waters of the Red Sea offer an ideal environment for coral growth, and great views for every dive or snorkel excursion. The reef system is also a popular destination for wreck diving, with many historic shipwrecks lying in its depths.
