Borneo op z'n best

Geweldige ervaring, dit was werkelijk Borneo op z'n best. Echt avontuur, inclusief speed- en longboats, jungle treks en overnachten in kampen in de jungle of bij mensen thuis. Best wel veel dieren gehoord en gezien, helaas ook muggen. Vergeet zeker geen goede muggenspray mee te nemen...
Als je Borneo op z'n best wil zien en van avontuur houdt, moet je niet twijfelen!

Ce fut une expérience merveilleuse. Le trekking dans la jungle et les promenades sur les petits bateaux étaient parmi nos favorites, mais la meilleure partie était en fait de rencontrer des gens locaux. On n'a pas vu tant d'animaux car la région est si grand et les animaux ont encore beaucoup d'espace, mais ça ne nous dérangeait pas du tout.
L'hébergement était sobre mais ok, et la nourriture était bonne étant donné que nous étions au milieu de la jungle.
N'hésitez pas, Mundooz vous donne une excursion fantastique!
