First, let's be clear: almost all of Sisaket's nature is clustered in two southern districts — Kantharalak (home to Pha Mo I Daeng and Preah Vihear) and Khun Han (waterfalls, volcanic-soil durian farms, forest temples). Both are about 1–1.5 hours from the city center, up against the mountains that mark the Thailand–Cambodia border. So this plan takes you south and has you sleep down there, rather than driving back into town every day. The sights are spread out, so a private car or a rental is basically a must for this trip.
The border situation to check before you set off
Pha Mo I Daeng, inside Khao Phra Wihan National Park, has been temporarily closed to tourism since 29 May 2025 due to tensions along the Thailand–Cambodia border, with no firm reopening date — it depends on the situation. Before you plan to go, always check the latest announcements from Khao Phra Wihan National Park and the current border news. Don't rely on old information. The plan below is written two ways — one if Pha Mo I Daeng is open as normal, and one if it's still closed — so you won't waste the trip whichever you run into.
How to get here, and what to drive around in
From Bangkok you can take a Lower Isan train straight to Sisaket station, or a coach from Mo Chit. If you're flying, land at Ubon Ratchathani airport and continue to the city center, about 1.5 hours. From the city, heading south to Kantharalak–Khun Han is another 1–1.5 hours. Public transport in this zone is very limited. The waterfalls and durian farms sit deep in the hills, and public transport barely reaches them. We'd suggest renting a car and driving yourself, or hiring a driver by the day — far more flexible.
The 2-day, 1-night nature plan
If you have two days, this fits nicely. Day one heads south to Kantharalak to pick up the clifftop viewpoints and cafés along the way. Day two runs the waterfall-and-volcanic-durian route around Khun Han, then grabs some souvenirs on the way home. There are plenty of rice-field cafés to stop at en route.

Khun Han — Samrong Kiat waterfall + volcanic-soil durian farms
Book the activities in your Sisaket trip ahead
Booking online ahead on Klook or GetYourGuide is usually cheaper than the gate and skips the queue. Pick only the experiences you actually want — prices and availability are shown live on each site.
If you have 3 days, what can you add
If you've got three days, there's no need to rush south on day one. Add a first day for the city side and the Khmer prasat, then head south for the two nature days. That way you see both sides of Sisaket — thousand-year Khmer history and the nature along the mountains.

If Pha Mo I Daeng is still closed, where to go for nature instead
The good news is Sisaket's nature isn't just Pha Mo I Daeng. Even if the clifftop viewpoint is closed, there are still waterfalls, forests, and fruit orchards on volcanic soil to visit around Kantharalak–Khun Han that are open as normal. Below are the spots you can use instead if you can't get into Pha Mo I Daeng on the day.
Samrong Kiat Waterfall
A shady forest waterfall at Ban Samrong Kiat, Bak Dong subdistrict, Khun Han district, dropping from a cliff about 8 m high. You can take the stairs down to the lower tier. Fullest in the rainy season. Open roughly 08:30–16:30.
Volcanic-soil durian farms, Khun Han–Bak Dong
Fruit orchards on volcanic soil. From Jun–Aug, many farms let you sit and eat durian on site — sweet and creamy with a milder smell. Farm-gate prices around 180–250 THB/kg.
Kantharalak rice-field cafés
Several cafés with rice-field and mountain views, like Nata Café on the road to Pha Mo I Daeng and shady backyard-style spots. Good for a break when the sun is harsh.
Wat Lan Khuat (Wat Pa Maha Chedi Kaew)
A forest temple in Khun Han decorated with more than 1.5 million glass bottles. The highlight is the four-gabled hall set over water. Open roughly 08:00–17:00, free to enter.
Rough budget per person
- 1 night's stay — a guesthouse or small resort in the south or city starts around 400–800 THB; a mid-range hotel in the city runs 800–1,500 THB
- Entry fees — Pha Mo I Daeng is normally about 40 THB per person (currently closed); waterfalls and temples are free or just have a parking/merit-as-you-wish charge
- Car — a self-drive rental runs about 1,000–1,500 THB a day plus fuel; split it if there are a few of you
- Food for 2 days — local food, cafés, and markets, about 500–800 THB for the whole trip
- Souvenirs — volcanic-soil durian (season only), orchard fruit, soil-dyed cloth, jasmine rice; budget as you like
When is the best time for nature in Sisaket
Each season gives a different mood. If you want a sea of mist over the cliffs and cool air, the cold season around November–January in the early morning is the prettiest and most comfortable (assuming Pha Mo I Daeng has reopened). If you want volcanic-soil durian straight from the tree, come mid-June to August — late June peaks, and there's usually a volcanic durian festival. The waterfalls are fullest in the rainy season around September; in the dry season the water thins out a lot. The Isan sun is harsh almost year-round, so walking outdoors in the morning or late afternoon is most comfortable — avoid 12:00–15:00 if you can.
What to eat along the nature route
The south doesn't have a lot of fancy restaurants, but the local food is good and the prices are friendly. With four ethnic groups here, the menu mixes Lao, Khmer, and Kuy. Below are the eats that, once you try them, make it clear why people get hooked. A few older dishes need ordering ahead or are easiest to find during festival season.
Volcanic-soil durian (season only)
The south's signature, grown on volcanic soil around Khun Han–Kantharalak. Sweet and creamy with a milder smell, thick flesh and small seeds. You can eat it straight from the tree from Jun–Aug.
Tilapia with sweet fish sauce and sadao
Sisaket is known for its farmed tilapia, fried crisp and drizzled with sweet fish sauce, eaten with blanched sadao (neem) — a touch bitter, a touch sweet. Plenty of local spots do it well.
Home-style larb-koi and om
Lao-Isan food you'll find at larb-koi shops across the district. Om is an offal stew with seasonal local vegetables, savory and rounded from the spice paste and lemon basil, eaten with hot sticky rice.
Som tam — bold Sisaket-style
A local take with a bolder mix and a punchier heat than the usual som tam. Eat it with fried tilapia or grilled chicken at local eateries across Kantharalak–Khun Han.
Pon pla and pla som
Homely dishes found in every kitchen. Pon pla is a boiled-fish chili dip eaten with fresh vegetables; pla som is fermented fish fried and eaten with sticky rice. Filling and tasty — order them together.
Rambutan and mangosteen from volcanic orchards (season only)
Same window as durian — the orchards around Kantharalak–Khun Han have fresh rambutan and mangosteen, picked straight from the tree, sweet and juicy, friendly prices. Good to take home too.
Coffee at a rice-field café
Cafés with rice-field and mountain views around Kantharalak, like Nata Café and backyard-style spots. Good for a coffee break when the sun is harsh, with a shady feel.
Thung Kula jasmine rice and khao hang
Sisaket sits in the Thung Kula Ronghai area, a source of fine jasmine rice. Khao hang is steamed-then-milled paddy that's fragrant and high in nutrients — a good thing to take home.
Getting ready for nature in the south
Wear shoes that handle slippery ground — waterfall rocks get wet and slick. Bring drinking water, a hat, and mosquito repellent, since many spots are in the forest. Fill up on fuel before heading south, as petrol stations out here are far apart. And most important of all, check the Khao Phra Wihan National Park announcements and the latest border news before you set off, every single time. If Pha Mo I Daeng is still closed, switch to the waterfall–durian–temple route and you won't waste the trip.
