I am unsure about the particular cost to Bario alone because our tour includes Miri, Mulu, Brunei, and Niah Cave. However, you need to note that there are limited flights from Miri to Barrio, Which means you must book in advance. Our travel plans were organized by Brighton Travel & Tour Sdn. Bhd., who can help you with planning your trip to Sarawak. You can contact them at Facebook: facebook.com/bttsb or 019-8846186/085-428899, look for Wilson.
