Phi Phi Islands – The Iconic & Colorful Escape

Background Story
Located in Krabi Province, the Phi Phi Islands are most easily reached from Phuket in just 45 minutes to 1 hour by speedboat. The islands gained worldwide fame in 2000 when The Beach, starring Leonardo DiCaprio, was filmed at Maya Bay – instantly making it one of the most iconic beaches on Earth.
But Phi Phi isn’t just about movie fame.
- The name “Phi Phi” comes from the Malay word Pulau Api-Api, meaning “Island of Mangroves,” as these trees once covered much of the area.
- Evidence shows that sea nomads (Chao Lay people) have lived here for centuries, preserving unique traditions.
- Maya Bay was closed for 3 years to allow nature to recover from over-tourism. Today, it’s open under strict eco-friendly measures: limited daily visitors and no swimming to protect corals.
Today, Phi Phi stands as a hub of diversity – stunning nature by day, vibrant nightlife by evening, and travel facilities for every budget.
Nature & Highlights
A Phi Phi Island tour from Phuket will introduce you to stunning limestone cliffs, turquoise waters, and white sandy beaches.
- Maya Bay: Crescent-shaped bay surrounded by cliffs over 100 meters high. Its emerald water and powdery sand make it world-famous. Now managed as an eco friendly island tour.
- Loh Samah Bay: One of the best snorkeling spots on Phi Phi Leh, home to parrotfish, clownfish, and lionfish.
- Bamboo Island: A tranquil escape with soft white sand, perfect for bamboo island snorkeling or simply relaxing away from the crowd.
- Monkey Beach: Known for its macaque residents – great for photos but remember not to feed them.
- Viking Cave: Famous for ancient wall paintings and swiftlet bird’s nest harvesting.
Phi Phi is the perfect blend of snorkeling, speedboat adventures, and vibrant lifestyle experiences.

Similan Islands – Thailand’s Underwater World Heritage

Background Story
The Similan Islands, located about 70 km off Khao Lak, Phang Nga, come from the Malay word sembilan, meaning “nine” – the original number of islands. Later, the park expanded to include nearby islands.
Declared as a National Marine Park in 1982, the Similans are internationally recognized:
- Ranked among the Top 10 Diving Sites in the World by global dive organizations.
- Closed annually from May to October to allow marine ecosystems to recover – a conservation measure that keeps the islands pristine.
- Scientists have recorded over 500 fish species, 200 coral species, and rare marine life such as manta rays and whale sharks.
No wonder the Similans are called “a diver’s dream” – a must-visit once in a lifetime.
