The origin of the name Kampong Kiudang is derived from the name of the tree 'Kayudang' according to the nickname of the Dusun community in ancient times. While the name 'Mungkom' is a Bong Mungkom language which means a type of durian fruit.

Majlis Perundingan Kampung (MPK) Kiudang created a tourism industry capable of generating the economy and prosperity of the community, tried to preserve this sector starting in 2011 through eco-tourism service products One Village One Product (1K1P) by highlighting the Taman Rekreasi Wasai Bedanu (Bedanu Waterfall Recreational Park) as the main visit to Kampong Kiudang. The Bedanu Waterfall Recreational Park transformation plan that was prepared said the MPK has succeeded in attracting many visitors by providing tour activities such as jungle tracking to caves, Sapok Waterdall and Batu Ampar visit herbal gardens and so on.

Seeing how important the tourism industry is to the progress of the village and to support the desire of the Sultan of Brunei towards a developed country in Vision 2035, efforts to strengthen the management and services of this industry continue by establishing cooperation which is cohesive with interested parties such as the Tourism Development Department of the Ministry of Primary Resources and Tourism, signed an MoU agreement with the Tutong District Tourism Coordination and Promotion Agency, established business cooperation with local tourism agents especially in helping and providing support in all aspects.
