BTTR, a state park in Perak gazetted in 2007, is one of the oldest tropical rainforests in the world.
Dating back 130 million years, the BTTR reserve offers a vast selection of nature and adventure packages, including wildlife and bird-watching, jungle trekking, as well as flora and fauna trails.
NCIA has been involved in the development of BTTR since 2010 through the BTTR Integrated Master Plan (BTTR-IMP). In 2013, NCIA completed the upgrading works of three base camps in BTTR that are located at Sungai Kejar, Sungai Papan and Sungai Tiang respectively. The upgrade was meant to provide an opportunity for tourists and visitors to experience ecotourism in the state park.
In 2017, NCIA completed the upgrading works for Pangkalan Aman Public Jetty in Pulau Banding, Gerik. The Jetty Complex and main gateway to BTTR is now known as the Hentian Royal Belum Amanjaya. In November of the same year, an interpretative centre was inaugurated at the complex, complete with information panels, a fun map of Royal Belum, a mural doodle with hornbill motif and a memorial wall.
