At Tam Coc you are rowed 3 kilometres up a river (and back) which wanders through amazing limestone mountains. The river passes through 3 limestone caves in the mountains. If you do this tour take a good torch with you as you can see a lot more detail on the roof of the caves. You are sitting in the boat for quite a long time so make sure you have protection from the blistering sun.
You dont need reservations, just go there, buy a ticket and enjoy!
