Guide to Sam Phan Bok


The Grand Canyon in Arizona has stood through time as one of the most iconic marvels of the world – but just the thought of hopping on a 22-hour flight to the US is toe-curling. Unbeknownst to most tourists though, is Sam Phan Bok; an otherworldly hidden gem that’s right here in Thailand.

Rivalling its distant American cousin, Sam Phan Bok is an expansive rock reef in Ubon Ratchathani that’ll leave your mouths agape in awe.

The name ‘Sam Phan Bok’ translates to ‘3,000 shallow lakes’ in the Isan language spoken in northeastern Thailand, and it’s clear why.

One look at the place and you’ll be transported to an almost moon-like planet, with what seem to be a thousand craters all around you. These holes were actually formed over a million years ago from the river’s rapids.

One peculiar rock to look out for the dog-shaped cliff. Legend has it that a long time ago, a city ruler discovered gold treasure beneath the rapids. A dog was left to guard the hole, but the ruler, consumed by greed, decided to take the gold and leave through another hole.

As such, the poor dog was left waiting until it passed away. Other tales recount a dog turning into stone while protecting the area

When here, don’t leave as soon as the sun sets. With such a vast area untouched by commercial buildings, it’s the perfect set-up for some stargazing action come nighttime.

The reefs are located in the Pho Sai district of Ubon Ratchathani, which is considered one of the four major cities in Thailand’s northeastern Isan region. 

A visit here will have you filling up your itinerary with lots to do such as temple hopping, so no need to worry about going out of your way just to pop by Sam Phan Bok for a day.

One can hitch a ride to Sam Phan Bok on a local pick-up, with prices starting at ~฿20. Taxi rides are the more comfortable option (from ~฿1,500) and can be taken from Pho Sai bus station.

Those really looking for an adventure can get here via a long-tailed boat along the Mekong River, which starts from ~฿500 (prices may vary depending on ride time). The best time to visit would be during dry season from December to May, where the rocks aren’t covered with water.

Though Thailand sees seasoned travellers all the time, it’s refreshing to discover new places to visit – even ones that have been around for centuries.
