Top 10 Largest Protected Areas in the World


A protected area is a designated location that has been preserved for its ecological, natural and/or cultural values.  Governments work with conservationists to ensure that these areas continue to function naturally, with minimal (if any) human management.  The preservation of many protected areas has stopped or slowed the extinction rate of several species.  Currently, there are over 160,000 protected areas in the world that cover 10 to 15 percent of the world’s surface area (both land and sea).

Listed below are the ten largest protected areas in the world.

10.  Northeast Greenland National Park

Size: 927,000 square kilometers

Encompassing the entire northeastern portion of Greenland, this is the largest national park in the world.  It is larger than 163 countries (there are roughly 194 countries in the world).  The land is inhabited by polar bears, walrus, arctic fox, snowy owl and musk oxen, among many other species.  Northeast Greenland is the most northerly national park in the world.

9.  Chagos Marine Protected Area

Size: 545,000 sq. km.

Part of the British Indian Ocean Territory, the Chagos Marine Protected Area is the largest marine reserve in the world.  Larger than the country of France, this marine reserve is located 500 kilometers south of Maldives.  The seven atolls of Chagos are a wonder to see and are rich in biodiversity.

8.  Phoenix Islands Protected Area

Located in the Republic of Kiribati, this protected area is the largest marine reserve in the Pacific Ocean and was the world’s first deep-water, mid-ocean marine protected area.  There are rumors that missing aviator Amelia Earhart crashed on one of the islands in 1937.

7.  Papahanaumokuakea Marine National Monument

Size: 360,000 sq. km.

This World Heritage-listed preserved area is a U.S. National Monument located in the state of Hawaii.  The monument is made up of ten islands and atolls of the Northwestern Hawaiian Islands.  The area is home to 7,000 different species, including the endangered Hawaiian monk seal.

The Great Barrier Reef contains the largest cluster of corals in the world and is home to several species of exotic marine life.  This park was established to protect a large part of Australia’s Great Barrier Reef from further damage.  Although humans are allowed to visit the area, permits are required for all activities (both recreational and commercial) and guidelines are very strict.

5.  Kavango-Zambezi Transfrontier Conservation Area

The protected area covers land in Angola, Botswana, Namibia, Zambia and Zimbabwe on the continent of Africa.  There are several national parks incorporated into this preserved area, including Chobe National Park, Hwange National Park, the Okavango Delta and Victoria Falls.  Designed to encourage tourism across several borders and the migration of mammals across borders, the Kavango-Zambezi Transfrontier Conservation Area was created by the Peace Parks Foundation and the World Wide Fund for Nature.

4.  Galapagos Marine Reserve

Size: 133,000 sq. km.

The Galapagos Islands are located 1,000kilometers off the coast of Ecuador.  The Galapagos Marine Reserve is the largest marine reserve in a developing country and the second largest reserve in the world.  This area is home to many species of marine life, including sharks, whales, turtles, fish and rays.  There is a mixture of hot and warm marine currents and freshwater and seawater, so there are several unique species in the area.  Charles Darwin studied many species here to form his Theory of Evolution.

3.  Great Limpopo Transfrontier Park

  1. Umm… isn’t Antarctica in the world? 14,000,000 sq km protected under the UN’s Antarctica Treaty and the Protocol on Environmental Protection to the Antarctic Treaty. Just sayin’…

    KAZA has an area of 440.000 km² (treaty month of August 2012).
    Therefore in my mind it is the largest transboundary conservation area in the world.
    kind regards

  3. You are missing out Papua Barat- or Indonesian West Guinea- 30% of it is National Park making it one of the largest in the world.
    It requires pre-approval for tourist visa including police clearance and Intel background check to make sure visitors (mainly scientists) are not NGO’s creating internal political problems.
    Add to that- it requires military escort & airlift- much is undiscovered and the areas is still inhabited by cannibals- last documented case was 2010.

    Though it may not be the largest protected area in the world but the Island of Ni’ihau which is the very most western island of Hawai’i is very highly protected. You need both state and governmental approval to go on to that island which usually boils down to scientists. I know that as I lived in Honolulu, Hawai’i for 2 years and worked at the Bishop Museum as their purchasing agent (Hawai’is’ State Museum and considered the world’s greatest museum for Pacificana studies in the world). Ni’ihau is protected better then Fort Knox, trust me on that one !

  5. I would put “Antarctica” at the top of the list, since it’s protected by UN Charter.
