This is an excellent place to visit and has been featured in many films like James Bond´s - Die Another Day or Lara Croft´s Tomb Raider.
On the east side of the river is a little restaurant where you can grab a slice of cake and a hot drink or something like that. There are toilets and you can also book one of the boat rides into the lagoon.
