About Koh Larn
Koh Larn (Ko Lan) is Pattaya's main island, just 45 minutes by ferry. While famous for its beaches, the island also has multiple dive sites around its perimeter with coral reefs dropping to 22m. The eastern side is more sheltered and has better visibility. Despite proximity to busy Pattaya, the reefs support decent marine life including macro favorites.
Tips
Visibility is best November–March. Avoid weekends when the island is packed with day trippers.
