About us

After many years of living in Koh Tao, away from France, Julien, the founder of the company, was in need of a new challenge. What better way to explore new horizons than to go discover the hidden treasures of Ang Thong National Marine Park? Unseen tours was then created. 12 years and numerous trips later, he continues to share his endless knowledge of the stunning islands and their secrets with his adventurous customers. Away from their daily routine, he wants them to enjoy the complete safari experience by venturing off the beaten path. Proud to offer this trip exclusively, the crew strives to make everyone part of the loving family as they embark on the unique journey that is exploring the breathtaking archipelago.
