Our voyage begins in the enchanting Ayutthaya, a UNESCO World Heritage Site where history comes to life. From there, we venture into the untamed wilderness of Thailand, visiting not one, not two, but three of the nation's natural World Heritage Sites: the awe-inspiring Huai Kha Khaeng Wildlife Sanctuary, the lush and sprawling Khao Yai National Park, the breathtaking Kaeng Krachan National Park, and the untamed wilderness of Kuiburi National Park. You'll witness the spectacle of wild waterbirds in their pristine habitat at Bueng Boraphet Swamp in Nakhon Sawan, experience the majesty of the elusive serow in the rugged terrain of Serow Hill, Saraburi, and witness the grandeur of Bryde's whales in the Gulf of Thailand.
