Mulu was declared an iconic UNESCO World Heritage Area, at 55,000 hectares, the biggest National Park in Sarawak.
Gunung Mulu National Park qualifies for all four of the World Heritage criteria. Fewer than twenty UNESCO World Heritage areas could manage this feat and these are what they mean for tourism: Superlative beauty – mountains, combined with huge river systems, a tropical rainforest and huge caves. The earth’s history and geo features are evident in the gigantic caves and the Pinnacles. Appreciate the biodiversity and ecological processes when you do adventure trekking or just stroll along the botany trail.
