Follow your guide past well-preserved ruins of temples and palaces, stopping at Wat Chaiwatthanaram along the banks of the Chao Phraya River. This 17th-century temple is known for its grand Khmer-style prang (tower) surrounded by smaller chedis, which resemble the Angkor temples in Cambodia.

On the way to your next stop, Khao Yai National Park, stop for lunch at a local restaurant. After the 2.5-hour transfer to Thailand's first national park, head straight to the Khao Yai Bat Cave to watch millions of bats emerge around sunset. They'll spend around 30 minutes out of the cave hunting and feasting on insects, forming thick black clouds over the red and orange-hued sky.

Day 3: Full-Day Tour of Khao Yai National Park, Transfer to Korat

Go for a refreshing swim in the natural pool below Haew Su Wat Waterfall

Lace up your hiking boots and get ready for a guided hike through Khao Yai National Park. There are seven trails to choose from depending on your interests and skill level, but two of the most popular ones lead to Haew Su Wat Waterfall. If you want to visit the cascade, choose between the easy 0.4-mile (0.8 km) Haew Suwat Nature Trail or the longer 4.4-mile (7 km) Nong Pak Chi Nature Trail to search for wildlife along the way. Keep your eyes peeled for monitor lizards, gibbons, and birds, as there are over 300 species in the park, including the rare great hornbill.

When you arrive at the waterfall, admire the 65-foot-tall (20 m) cascade surrounded by greenery and towering trees. Then, jump into the natural pool below for a refreshing swim in the clear water. After the hike, meet your driver for a 2.5-hour transfer to Thailand's third-largest city, Nakhon Ratchasima, also known as Korat.
