There is a superb underwater world hidden under the ocean. There are colourful coral reefs, extraordinary marine life and views which are hard to forget.
At least five beaches in Southeast Asia are included within the list of the world’s 50 best beaches. The study, conducted by the British newspaper The Daily Telegraph, was published in early August 2024. The beaches come from Vietnam, Thailand, Indonesia and the Philippines. The best diving spots are also in these countries.
The list was compiled by travel experts based on criteria reminiscent of wildlife, panoramic views, atmospheric destinations, luxury hotels, quiet spots, family-friendly sandy beaches and more.

Immerse yourself in paradise
Southeast Asia offers a few of the world’s best diving spots for macro photography and showcasing an incredible diversity of creatures. From pygmy seahorses and colourful nudibranchs to crustaceans, rare anglerfish and even historic shipwrecks.
With warm water, good visibility and massive marine biodiversity, these locations are a dream for divers who concentrate to the small print of the underwater world. The islands of Southeast Asia also remain a top alternative for divers of all levels. Whether you are a newly certified diver or an experienced explorer, these ten islands offer unique dive sites that mix natural beauty with modern environmental friendliness.
Here are a few of the most beautiful diving spots in Southeast Asia you could visit.
Tubbataha Reefs Natural Park within the Philippines
The Philippines offers quite a lot of diving experiences, but there’s one most famous site, Tubbataha. This top diving spot is known for its crystal clear waters and incredible marine biodiversity. Tubbataha Reef National Park is home to over 360 species of coral and was designated a UNESCO World Heritage Site in 1993, ensuring its protection from industrial fleets.
Tubbataha Reef is situated around two lagoons and an enormous atoll formed by an extinct volcano. The remaining seascape is an infinite sea wall dotted with soft corals swaying with the currents.
Its location within the open ocean implies that calm to strong currents are common, and the deep partitions can pose a challenge to inexperienced explorers. This island is just available for brief periods as a result of the short diving season.
Raja Ampat, Indonesia
Located in eastern Indonesia, Raja Ampat means “Four Kings”. Considered the crown jewel of the diving world, Raja Ampat boasts crystal clear waters, untouched coral reefs and an incredible diversity of marine life.
It’s no wonder that Raja Ampat has been named the world’s center for coral reef diversity by the World Wildlife Fund (WWF). This archipelago boasts over 1,300 species of fish and 530 coral reefs. Visibility is great, but currents are sparse and powerful, so Raja Ampat is best explored by more advanced divers with drift diving experience.
Indonesia offers probably the most diverse diving routes. Divers may visit Indonesia multiple times, but still discover something latest during their trip.
National Marine Park on Similan Island in Thailand
Thailand offers some exciting diving spots, however the routes usually are not as extensive as those in Indonesia and the Philippines. Thailand offers a novel mix of wealthy cultural experiences and world-class diving.
The Similan Islands are an archipelago famous for its massive granite rock formations, visible each above and below the water, and surrounded by white sandy beaches. The underwater topography is different on either side of the islands; the eastern side boasts gently sloping hard coral reefs, while the western side is home to massive submerged granite boulders which have created channels and swimming lanes.
The archipelago consists of nine small islands west of Phuket, most of that are uninhabited but offer stunning beaches and crystal clear waters teeming with tropical fish.

Today’s motion, tomorrow’s legacy
Coastal and marine ecosystems in Southeast Asian countries are closely interconnected. Marine species often rely on quite a lot of offshore habitats throughout their life cycle.
This ecological connectivity is crucial for maintaining genetic diversity and resilience, enabling marine populations to resist environmental change and the impacts of human activities.
However, with climate change accelerating, overfishing accelerating the decline of fish stocks, and habitat destruction weakening the foundations of ecosystems, the necessity for a coordinated approach to marine conservation at a regional scale is becoming increasingly urgent.
We can still save the ocean, even whether it is small. Let’s discover what we will do.
- Reduce waste and use of plastics
- Don’t indiscriminately catch marine life
- Do not touch or take away from coral reefs
- Volunteering in marine conservation and conservation
