1.1. Khao Yai National Park
Covering over 2,160 square kilometers in the Phanom Dong Rak mountain range, Khao Yai National Park straddles the borders of Nakhon Ratchasima, Nakhon Nayok, Saraburi, and Prachin Buri provinces. The natural marvels of Khao Yai include over 200 species of birds; scenic waterfalls and jungle-covered mountains, all accessible via over 20 trekking trails. The park’s high elevation keeps it cool all year round, but the park is at its best between October and February. Tourism Thailand page.
1.2. Mu Koh Surin National Park
To see Thailand’s undersea riches, visit Mu Koh Surin National Park – a series of islands in the Andaman Sea lined with coral reefs and an almost endless parade of colorful schools of fish. Mu Koh Surin is a diver’s dream, and snorkelers ought to look out for the harmless but gigantic whale shark endemic to these waters. Koh Surin Nuea, where the Park Rangers’ Station can be found, also hosts bungalows and a campsite for overnight visitors. Peak season is between November and April. Tourism Thailand page.
1.3. Doi Inthanon National Park
The Park surrounding Thailand’s tallest peak Doi Inthanon attract hikers and birdwatchers who appreciate the area’s remote, chilly natural beauty. Attractions in Doi Inthanon National Park include the scenic Namtok Mae Pan waterfall, the longest in Chiang Mai; the mysterious Tham Bori Chinda cave; twin pagodas Phra Mahathat Napha Methanidon and Phra Mahathat Naphaphon Bhumisiri; and the Doi Inthanon Royal Project, launched to wean local hill tribes away from illegal opium cultivation.
