The most suitable period to visit Kaeng Sam Phan Bok is from December to May. From July to the end of October, the water covers the holes. Among the notable holes and rock formations, we can list: a rock whose shape resembles the head of a dog, holes in the shape of a heart or Mickey Mouse's head.
It is recommended to prefer to visit Sam Phan Bok at the beginning or end of the day when the heat is more bearable because there are no trees, no shade, it is a desert landscape with water, but it can be very hot!
Sam Phan Bok can be visited in the dry season. From July to the end of October, the interesting part is usually submerged.
Local tourists mostly come to Sam Phan Bok on weekends. So it is when the place gets crowded. The songthaew service with a guide to walk you to see all the interesting holes costs 200 THB per car (I will say 8 people max). On weekends and public holidays, the local children serve as guides, and during the weekdays one of the souvenir sellers does it. It's better to come here on weekdays as you'll probably have the site to yourself with no other visitors. The tour takes around 1h30. There are also boat tours but, from my point of view, they are less interesting because they do not take you to see the most famous rock formations and holes and that remains the main interest of Sam Pan Bok. The cruise costs 500 THB per boat. The ideal would be to do both and then, it takes 3 hours.

The new arrival point is quite far from the interesting area, so the songthaew service is really usefull and cheap so take it !. Songthaews are parked in front of the sign. There are a few stands selling souvenirs and drinks as well as a restaurant stand in the parking lot where you arrive.
