What Travellers Say
Reviews Summary
Sam Phan Bok is lauded as a stunning natural wonder, particularly during the dry season when its thousands of eroded rock holes are visible, earning it the nickname 'Thai Grand Canyon.' Visitors appreciate the unique geological formations, the opportunity for photography, and the beautiful sunset views. However, some find the local transport arrangements and potential costs for pickup trucks or guides to be a point of contention, with a few suggesting they are not always necessary.
"Really awesome & stunning place to visit
When the Mekong river is on its low (January & February) this becomes the Thai Grand Canyon.....a must see place. You need a tour guide and he knows how to take very beautiful photos."
Marcel Coops
"This place is beautiful. Definitely worth going a bit later so it's not too hot, and so you can catch the stunning sunset.
They insist you get a pickup truck (they charged us 200 Thai Bhat), however I think the walk would've been fine tbh. They also try guide you but YOU DO NOT NEED ONE. I'm not sure how much they charge but this is an easy place to explore and is not too big. We saw people with guides and they don't venture very far anyway, we saw more without them I'd say.
It was expensive to get here from Ubon as we didn't have our own vehicle and it doesn't seem like there are tours but it was worth it regardless."
Isaac Perry
"Really beautiful yet cool place to visit. We took a 2 hour taxi from Ubon Ratchathani and were dropped off at a place to take a boat there (1,500 baht). From reading reviews I knew this wasn't totally necessary so we asked the driver to take us to the part where you can walk. It took 10 minutes to drive there and then we took a 5-10 minute drive (200 baht) to the rock formation. We then had the freedom to walk around and stayed till sunset. The taxi cost about £60 for there and back and we arrived for 3:30pm so it wasn't too hot. Highly recommend!"

Frequently Asked Questions
🚇 🗺️ Getting There
Sam Phan Bok is about a 2-hour drive from Ubon Ratchathani. You can hire a taxi or arrange for a local pickup truck. Some visitors have found it expensive to get there without their own vehicle, so planning transport in advance is recommended.
While you can walk from the car park, many visitors opt for a local pickup truck to get closer to the main rock formations. This usually costs around 200 Thai Baht.
Information on organized tours can be limited. Many visitors arrange private transport from Ubon Ratchathani. It's worth checking with local tour operators or your accommodation for any available packages.
You can drive to the general area, but you'll likely need to switch to a local pickup truck to access the specific rock formations, especially during the dry season.
The most common method is to hire a local pickup truck from the parking area. This short drive gets you right to the heart of the eroded sandstone landscape.
🎫 🎫 Tickets & Entry
While there isn't a formal entrance fee for the natural park itself, you will likely pay for local transport like pickup trucks or boat hires. Guides may also expect tips.
Sam Phan Bok is a natural attraction and doesn't have strict opening hours. However, it's best to visit during daylight hours, especially to appreciate the rock formations and for safety. Visiting later in the day can also help avoid the midday heat.
No advance booking is typically required for Sam Phan Bok as it's a natural site. Your main 'booking' will be for transportation to and within the area.
The dry season, specifically January and February, is crucial as the Mekong River's water levels are low, revealing the thousands of rock holes. Visiting during the rainy season means the area will be underwater.
Be prepared for costs related to local transport (pickup trucks, boats) and potentially tips for guides. While guides are often free, tipping is highly recommended for their service.
📸 📸 Photography
The eroded sandstone holes themselves are the main attraction. Look for unique shapes like vases or animal figures. The sunset over the Mekong River also provides stunning photographic opportunities.
Some visitors mention hiring guides who are skilled photographers. While not essential, they can help capture beautiful shots, especially during sunset.
A wide-angle lens is great for capturing the vastness of the rock formations. A polarizing filter can help manage reflections on wet surfaces. Don't forget a sturdy tripod for sunset shots.
Drone regulations can vary. It's advisable to check local rules and obtain any necessary permits before flying a drone over Sam Phan Bok to avoid issues.
Early morning or late afternoon, especially leading up to sunset, offers the best light for photography. The golden hour will enhance the textures and colors of the rock formations.
🍽️ 🍽️ Food & Dining
Yes, there is a cafe located adjacent to the parking area where you can get refreshments. For more extensive dining options, you'll likely need to return to Ubon Ratchathani or nearby towns.
Bringing your own water and snacks is a good idea, especially if you plan to spend several hours exploring. Remember to take any trash with you to keep the area clean.
The immediate area has limited dining. You'll find basic refreshments at the on-site cafe. For a wider variety of Thai cuisine, it's best to explore options in Ubon Ratchathani or smaller towns en route.
It's advisable to have a meal before you go or plan to eat after your visit, as dining options directly at the site are minimal.
While Sam Phan Bok itself is a natural attraction, exploring Ubon Ratchathani will offer opportunities to try Isaan (Northeastern Thai) specialties like Som Tum (papaya salad) and Laab (minced meat salad).
