Nakhon Nayok is a small province north-east of Bangkok, within about an hour's drive according to the Tourism Authority of Thailand (TAT), and Thais use it as a weekend escape for waterfalls, river trips and farm stays. Its two best-known waterfalls, Nang Rong and Sarika, both lie inside Khao Yai National Park, so park rules and a park fee apply.
TAT describes the province as a popular weekend destination for Thais that sees relatively few foreign visitors. The town is unremarkable; the attraction is the countryside at the foot of the hills, where streams come down from the Khao Yai massif towards the plain. If you have a free weekend in Bangkok and want green hills without a long journey, it is a good choice, but it works best with a car or a driver.

Nang Rong and Sarika: two park waterfalls
Both falls belong to Khao Yai National Park, the big park on the other side of the mountains, but you reach them from the Nakhon Nayok side, not from the main Khao Yai plateau. The Department of National Parks (DNP) lists Sarika as a Khao Yai attraction in Nakhon Nayok, and in July 2026 it presented a development plan for Nang Rong waterfall in Khao Yai National Park to a Senate committee.
TAT describes Nang Rong as cascading over three levels with several pools below, set in thick forest. Sarika is the other well-known fall, in Sarika sub-district of Mueang Nakhon Nayok district. Both are popular with Thai families at weekends, so go early in the day, or on a weekday, if you want quiet water.
Because the falls are in the national park, the park's entry fee applies. Khao Yai is in the DNP's 200-baht category for foreign adults, but the park's own site charges 400 baht for its central zone, and we could not confirm which rate the Nakhon Nayok gates use. Take cash for either.
Nakhon Nayok's falls close at short notice after heavy rain. Khao Yai closed Sarika on 25 September 2026 because of flash floods, at first for two days, and the whole park closed the same day. The park reopened on 6 October 2026, and Sarika was not on the list of sites still closed. Before you drive out, check the park's Facebook page or call 08 6092 6527.
Waterfalls in the rainy season are where flash floods and slippery rock catch visitors out. Our guide to waterfall and river safety explains how to read the warning signs; read it before you swim.
Khun Dan Prakan Chon dam: the viewpoint
The Khun Dan Prakan Chon dam is one of the province's main sights. TAT describes walking across the dam for the view over the reservoir and the forested hills behind it, and lists kayaking and other water activities on the reservoir.
Treat it as a viewpoint and a stop on a drive, not a full day out. Go in the late afternoon, when the light is softer and the heat has eased, and combine it with one of the waterfalls. We could not find an official page with visiting hours, so expect parts of the crest or the car park to be closed at times.
Rafting: what is open in late 2026
Nakhon Nayok is best known in Thailand for soft adventure, and rafting is the headline. In a 2019 feature, TAT described the white-water stretch at the Kaeng Hin Phoeng rapids, rated by TAT as class 3 to 5, as the most popular white-water rafting in Thailand because it is so close to Bangkok. Those rapids are inside Khao Yai National Park and remained closed when the park reopened on 6 October 2026, while the river area is monitored and repaired.
That leaves gentler trips on the rivers and the reservoir, run by private operators. We could not verify the rafting season, prices or any operator's licence, so check before you pay. Ask whether the operator holds a tour business licence from the Department of Tourism, whether life jackets and helmets are provided and what happens if the river is too high. Our guide to checking a licensed tour operator shows how. The UK Foreign Office advises taking care when rafting or kayaking on rivers, particularly in the rainy season; after heavy rain, stay off the water.
Wild elephants near the villages
The forest edge around Sarika is elephant country. On 14 March 2026, an 87-year-old resident of Sarika sub-district was killed by a young wild bull elephant near his home, according to the DNP, which has since stepped up patrols to push elephants away from villages. A well-known bull known as Phlai Sarika also ranges in the area, and the DNP reported him alive and healthy in September 2026.
For visitors, the rules are simple. Never get out of the car to approach an elephant on the road, keep your distance, do not use the horn or a flash, and drive slowly at dusk and after dark on roads near the forest. Our article on dangerous animals in Thailand covers other wildlife.
Cafes, farm stays and where to sleep
Most places to stay are resorts, cafes with rooms and homestays aimed at Thai weekenders from Bangkok. TAT mentions working farms that offer homestays and agricultural learning centers, which make a good base if you want something more local than a resort. We do not name individual businesses on this page; choose a place near the falls you most want to see, so you can reach them before the crowds.
Friday and Saturday nights fill first, and Thai long weekends are the busiest of all. Our list of Thai public holidays shows which weekends to avoid or book early. Sunday nights and weekdays are much quieter and often cheaper.
Getting there without a car
Nakhon Nayok is easiest by car. The falls, the dam and the cafes are spread along different roads, and without your own transport you will spend much of the weekend waiting. A car with driver from Bangkok is the simplest option for a group; agree the route, the number of stops and the return time in advance.
Buses and minivans run from Bangkok to Nakhon Nayok town. Our guides to long-distance buses and minivans explain terminals, classes and safety. They are usually described as leaving from the Northern Bus Terminal (Mo Chit) or the Rangsit area, but we could not confirm a current timetable or fare with the Transport Co., so ask at the terminal. From the town, local songthaews, the shared pickup trucks, and taxis can take you onward; agree the fare first.
If you drive yourself, our sister site has a guide to driving in and out of Bangkok, the hardest part of the trip. Our own page on renting a car in Thailand covers licences and insurance.
Floods in late 2026
Parts of Nakhon Nayok flooded in late September and October 2026. The DNP helped flood victims in the province on 27 September, and on 8 October it was still running mobile kitchens in Ongkharak district. We found no later notice by 27 October 2026. If you plan a weekend in the rainy season, check the weather and local news first; our page on traveling in the rainy season explains what to expect.
Frequently asked questions
Is Nang Rong waterfall inside Khao Yai National Park?
Yes. The Department of National Parks describes Nang Rong as a waterfall in Khao Yai National Park, and Sarika too. That means the national-park entry fee applies; for foreign adults it is 200 or 400 baht depending on the rate the gate uses, so check on arrival.
Can I go rafting in Nakhon Nayok in November 2026?
The best-known white-water stretch, the Kaeng Hin Phoeng rapids in Khao Yai National Park, stayed closed when the park reopened on 6 October 2026. Gentler trips run by private operators may be available; check the operator's Department of Tourism licence and the river level first.
How do I get from Bangkok to Nakhon Nayok without a car?
Buses and minivans run from Bangkok to Nakhon Nayok town, and songthaews or taxis go onward from there. We could not confirm a current timetable, so ask at the terminal. For a weekend of waterfalls, a car with driver saves a lot of waiting.
Are the Nakhon Nayok waterfalls open after the 2026 floods?
Khao Yai National Park, which includes Nang Rong and Sarika, reopened on 6 October 2026 except the Khao Khiao road and Kaeng Hin Phoeng. Sarika was closed from 25 September; check the park's Facebook page or call 08 6092 6527 before you travel.
Is Nakhon Nayok the same as Khao Yai?
No. Nakhon Nayok is a separate province below the southern slopes of the Khao Yai massif. Its waterfalls are in Khao Yai National Park, but the park's main plateau, viewpoints and night safari are usually reached through the northern gate on the Pak Chong side, which our Khao Yai guide covers.
