There are a few buses and minivans from Pakse that include a boat ride to Si Phan Don. If you are travelling from Cambodia, you can take a van from Kratie, Stung Treng or Banlung for about 15$, which also include a boat ride to Don Det or Don Khong.

Grottes de Pak Ou
Nous vous recommandons de rejoindre Ban Pak Ou en tuk tuk, puis de prendre un canoë à moteur pour traverser la rivière jusqu'aux grottes.
