There is a lot in Nakhon Nayak for lovers of nature to see and explore. The northern part of the province is situated amongst the colossal Dong Phaya Yen mountain range, and most of that area is covered by the lush green jungle of the spectacularly beautiful Khao Yai National Park.
In the central part of the province you will find the flowing waters of the Nakhon Nayok River. There are many opportunities to hire various kinds of boats around the area as this river is perfect for kayaking and canoeing. You can take out kayaks and canoes for the entire day and use your craft to explore the narrow tributaries at Khlong Wang Takhrai, which lead through a vast coffee plantation.
A short bus ride away from town is the Wang Takhrai Botanical Garden and the popular Wang Takhrai waterfall. There are also many other waterfalls to discover in the province such as Nam Tok Nang Rong, the nine-tiered Sarika waterfall and also the stunning Lan Rak waterfall. Another beautiful waterfall is Nam Tok Heo Narok, where the water cascades from a 200 metre cliff.
For those interested in the rich history of the area, a visit to the Dong Lakhon Ancient City should be high on the agenda. Located 9 kilometres south of the town, this is an ancient town of the Dvaravati period (about 6th-13th centuries). Don't forget to pay a visit to the local museum to discover more about the area's interesting past and to see well labelled displays of ancient Buddha images.
Worth looking out for are the long awaited Nakhon Nayok Canoe Races, which commence at the Wang Takhrai Canal Bridge in Tambon Sarika and end in the Nakhon Nayok River near the provincial capital, a distance of 5 kilometres. The races take place at various times throughout the year and tourists are welcome to join in the fun and try to beat the local contestants.
