Mount Api is a
limestone mountain located in
Gunung Mulu National Park in
Sarawak, Malaysia. It is part of the same formation as
Mount Benarat and Mount Buda. Mount Api is notable for its striking limestone
karst formations, commonly known as "the pinnacles". The mountain hosts many
caves, with passages linking to the massive
Clearwater Cave system. It features a great diversity of
pitcher plants, with at least eight different species recorded on the mountain. This 2019 photograph shows the karst pinnacles near the peak of Mount Api.
