Trinidad (Bolivia)

Bit of a freaky place that used to be a zoo where you have a chance of running into a turtle, capybara, yacare caiman, or anaconda. So, watch where you step, and hopefully the crocodilian isn't looking for a leg to munch on.

Platforms constructed around 5,500 years ago by various civilizations for purposes of irrigation, today they are important archeological sites for the ancient local cultures. The most impressive ones are Loma Suarez and Loma Chuchini.

A human-made hill close to the originally believed to have been built by the Moxos Civilisation. It is now an army village and you might need an ID to get in. Nothing very impressive the hill itself. But the view from the hill is rewarding. You can also eat some nice fish (Bs. 30) or take a there-and-return boat ride in Ibare River (to see animals you have to go by boat further).

A private but badly run ecological reserve with animals held in cages and such. Probably not worth the support and widely overpriced (also the accommodation which is beyond US$200), but check it out by yourself it is close to Loma Suárez.

Jump on a cargo boat and go to Guayaramerín, at the border with Brasil. This is unforgettable experience to see river Mamore and surroundings (the river is winding), and to experience daily life of cargo boat men. The trip may take 5-7 days in dry season, when there's less water in the river. With more water, the trip is faster, i.e. 3 days. Boats leave when full. For where and when to jump in, ask at Distrito Naval (naval neighborhood; 6 de Agosto corner Meliton Villavicencio) in Trinidad. Look for captainships (capitanias) for ports Almacen and Barador. They will direct you to a corresponding port, or maybe port Heralda. Go there, and deal the price directly. With information, guys in Beni tourist information office can help too, but then they'll direct you to "distrito naval".
