Java and Bali protect remarkable habitats, from volcanic highlands and coastal mangroves to savannas and marine reefs. The seven parks in the original roundup are not interchangeable adventure playgrounds; several include strictly protected wildlife, volatile volcanic terrain and seasonal fire risks. Before booking any activity in October 2026, consult the particular park’s latest access notice and Indonesian geological alerts.

How to Plan a Responsible Trip
Which parks suit which visitor?
For marine ecology consider the Thousand Islands or parts of West Bali; for forest learning Halimun Salak or Ujung Kulon; for geological interpretation authorised Merapi or Bromo areas only when open. Do not sell dangerous summit approaches as a casual park activity.
