Mount Bromo and Semeru in East Java.

Hiking and camping in the mountains are popular adventure activities. Some mountains contain ridge rivers, offering rafting activity. Though volcanic mountains can be dangerous, they have become major tourist destinations. Several tourists have died on the slopes of Mount Rinjani, Indonesia's second highest volcano and a popular destination for climbers visiting Lombok in eastern Indonesia. Popular active volcanoes are the 2,329-metre (7,641 ft) high Mount Bromo in the East Java province with its scenic volcanic desert around the crater, the upturned boat shaped TangkubanPerahu and the volcanic crater KawahPutih, north and south of Bandung respectively and both with drive-in access up to the crater, the most active volcano in Java, Mount Merapi near Yogyakarta, and the legendary Krakatau with its new caldera known as anakkrakatau (the child of Krakatau). GedePangrango volcano in West Java is also a popular hiking destination, especially among domestic hikers.

In Sumbawa, Mount Tambora with its historical massive volcanic eruption back in 1815 that produced massive caldera also had gained attention among hikers. In neighbouring island of Flores, the three-coloured volcanic crater-lake of Kelimutu is also hailed as one of Indonesia's natural wonder and had attracted visitors worldwide. Puncak Jaya in the Lorentz National Park, the highest mountain in Indonesia and one of the few mountains with ice caps at the (tropical) equator offers the opportunity of rock climbing. In Sumatra, there are the remains of a supervolcano eruption that have created the landscape of Lake Toba close to Medan in North Sumatra.

Bogor Botanical Gardens established in 1817, and Cibodas Botanical Gardens established in 1862, are two among the oldest botanical gardens in Asia. With rich collections of tropical plants, these gardens is the centre of botanical research as well as tourism attraction since colonial era.

There are 50 national parks in Indonesia, of which six are World Heritage listed. The largest national parks in Sumatra are the 9,500-square-kilometre (3,700 sq mi) GunungLeuser National Park, the 13,750-square-kilometre (5,310 sq mi) KerinciSeblat National Park and the 3,568-square-kilometre (1,378 sq mi) Bukit Barisan Selatan National Park, all three recognised as Tropical Rainforest Heritage of Sumatra on the UNESCO World Heritage list. Other national parks on the list are Lorentz National Park in Papua, Komodo National Park in the Lesser Sunda Islands, and Ujung Kulon National Park in the west of Java.

To be noticed, different national parks offer different biodiversity, as the natural habitat in Indonesia is divided into two areas by the Wallace line. The Wallacea biogeographical distinction means the western part of Indonesia (Sumatra, Java, Kalimantan) have the same flora and fauna characteristics as the Asian continent, whilst the remaining eastern part of Indonesia has similarity with the Australian continent.

Many native species such as Sumatran elephants, Sumatran tigers, Sumatran rhinoceros, Javan rhinoceros and orangutans are listed as endangered or critically endangered, and the remaining populations are found in national parks and other conservation areas. Sumatran orangutan can be visited in the Bukit Lawang conservation area, while the Bornean orangutan can be visited in TanjungPuting national park, Central Kalimantan. The world's largest flower, rafflesiaarnoldi, and the tallest flower, titan arum, can be found in Sumatra.

The east side of the Wallacea line offers the most remarkable, rarest, and exotic animals on earth. Birds-of-paradise, locally known as cendrawasih, are plumed birds that can be found among other fauna in Papua New Guinea. The largest bird in Papua is the flightless cassowary. One species of lizard, the Komodo dragon can easily be found on Komodo, located in the Nusa Tenggara lesser islands region. Besides Komodo island, this endangered species can also be found on the islands of Rinca, Padar and Flores.
