Khung Kraben Bay Aquarium is a free aquarium located in Chanthaburi province, Thailand, near the scenic Khung Kraben Bay. It’s compact but well-curated and showcases the diverse marine life found in the Gulf of Thailand.

The facility features a variety of tanks housing colorful tropical fish, crustaceans, and other sea creatures. It’s not that well maintained but it’s free to visit and part of the Laem Sadet National Park on the southern part of the Khung Kraben Bay, which also includes mangroves forests and the Aquaculture Demonstration Unit.
