Visitors to Hawaii Volcanoes National Park must adhere to several rules. First, all visitors are required to stay on designated trails and pathways. This is for their safety as the park contains active volcanoes that can be dangerous. Second, pets must remain leashed at all times when in the park and cannot enter any buildings or areas with thermal features. Third, visitors should not leave behind any trash or other items and must respect wildlife by not feeding them. Campers must obtain a permit before setting up a campsite within the park boundaries.
