==History== thumbnail|Plaque commemorating the Ko Chang battle
Prior to World War II, Ko Chang was little known. During this period, the few families there made a living growing coconuts and fruits.{{Citation needed|date=October 2013}}
On 17 January 1941, Ko Chang was the scene of the Battle of Ko Chang between the Royal Thai Navy and a much stronger Vichy French naval squadron, in which the French won a decisive victory. Ko Chang Yutthanawi Day, which occurs in late-January at the Ko Chang Yutthanawi Memorial on Laem Ngop, commemorates the Royal Thai Navy's engagement against the French colonialists. There is an exhibition by the Royal Thai Navy, and merit-making and tribute rites are performed for those killed in the battle.{{Citation needed|date=May 2018}}
==Geography== Ko Chang is part of an archipelago of 52 islands. It is approximately {{convert|30|km|mi|abbr=on}} long by {{convert|14|km|mi|abbr=on}} wide. It is part of the Mu Ko Chang National Park, which covers an area of {{convert|650|km2|sqmi|abbr=on}}, of which 70 percent is offshore.<ref name=TAT />
It is a mountainous island, with Khao Salak Phet being the highest peak at {{convert|744|m|ft|abbr=on}}. The island is known for several waterfalls, coral reefs, and rainforests.
The main settlements on the west coast are around Sai Khao, Hat Kai Mook, Hat Kai Bae, Ban Klong Prao and the fishing village of Bang Bao on the south coast. The island's administrative centre is Ban Dan Mai on the east coast.
==Climate== Most of Thailand receives between {{convert|1200|mm|in|abbr=on}} and {{convert|1600|mm|in|abbr=on}} of precipitation per year. Two provinces, Trat and Ranong, receive more than {{convert|4500|mm|in|abbr=on}} a year, making them the wettest places in the country.<ref>{{cite web |title=The Climate of Thailand |url=https://www.tmd.go.th/en/archive/thailand_climate.pdf |website=Thai Meteorological Department (TMD) |access-date=21 June 2019 |page=4 |archive-date=11 April 2019 |archive-url=https://web.archive.org/web/20190411211732/https://www.tmd.go.th/en/archive/thailand_climate.pdf |url-status=dead }}</ref>
==Wildlife== Ko Chang is home to populations of 29 species of mammals, for example, the stump-tailed macaque, the small Indian civet, the small Asian mongoose, 61 bird species, and a number of snakes and deer.
The Ko Chang frog (''Limnonectes kohchangae'') was originally thought to be an endemic species, but has also been found on the mainland.
==Administration== The island forms a district (''amphoe'') in the province of Trat. It was formed on 30 April 1994, when it was split off from Laem Ngop district, at first being classed as a minor district (''king amphoe'').<ref>{{cite journal|journal=Royal Gazette|volume=111|issue=42 ง|pages=24|script-title=th:ประกาศกระทรวงมหาดไทย เรื่อง แบ่งเขตท้องที่อำเภอแหลมงอบ จังหวัดตราด ตั้งเป็นกิ่งอำเภอเกาะช้าง|url=http://www.ratchakitcha.soc.go.th/DATA/PDF/2537/D/042/24.PDF|archive-url=https://web.archive.org/web/20080409014759/http://www.ratchakitcha.soc.go.th/DATA/PDF/2537/D/042/24.PDF|url-status=dead|archive-date=9 April 2008|date=May 26, 1994|language=th}}</ref> On 15 May 2007, the nation's 81 minor districts were upgraded to full districts.<ref>{{cite news|url=http://www.manager.co.th/Politics/ViewNews.aspx?NewsID=9500000055625|work=Manager Online|script-title=th:แถลงผลการประชุม ครม. ประจำวันที่ 15 พ.ค. 2550|language=th|archive-date=16 May 2011|access-date=14 September 2007|archive-url=https://web.archive.org/web/20110516212636/http://www.manager.co.th/Politics/ViewNews.aspx?NewsID=9500000055625|url-status=dead}}</ref> With publication in the ''Royal Gazette'' on 24 August, the upgrade became official.<ref>{{cite journal|journal=Royal Gazette|volume=124|issue=46 ก|pages=14–21|script-title=th:พระราชกฤษฎีกาตั้งอำเภอฆ้องชัย...และอำเภอเหล่าเสือโก้ก พ.ศ. ๒๕๕๐|url=http://www.ratchakitcha.soc.go.th/DATA/PDF/2550/A/046/14.PDF|archive-url=https://web.archive.org/web/20070930165121/http://www.ratchakitcha.soc.go.th/DATA/PDF/2550/A/046/14.PDF|url-status=dead|archive-date=30 September 2007|date=August 24, 2007|language=th}}</ref>
Ko Chang district is divided into two sub-districts (''tambons'') which are home to nine villages (''mubans''):
1. Ko Chang ({{langx|th|เกาะช้าง}}), consisting of four villages with 3,010 inhabitants: *Ban Khlong Nonsi *Ban Dan Mai *Ban Khlong Son *Ban Khlong Phrao
2. Ko Chang Tai ({{langx|th|เกาะช้างใต้}}), consisting of five villages with 2,346 inhabitants: *Bang Bao *Ban Salak Phet *Ban Chek Bae *Ban Salak Khok *Ban Salak Phet Nuea
==Transport==
===Air=== Ko Chang has no airport. The nearest airport is Trat Airport<ref>{{Cite web|url=https://www.bangkokair.com/pages/view/trat-airport |title=Trat Airport - Bangkok Airways |last=Airways |first=Bangkok |website=www.bangkokair.com |access-date=2016-04-26 |url-status=dead |archive-url=https://web.archive.org/web/20160429003428/http://www.bangkokair.com/pages/view/trat-airport |archive-date=2016-04-29 }}</ref> {{convert|17|km|mi|abbr=on}} from the Ao Thammachat Ko Chang ferry terminal on the mainland.
===Road=== There are two main roads on Ko Chang, running the length of the east and west coasts. Both roads start at Ao Sapparot in the north, near the ferry piers. Shorter roads branch out to Ploytalay Resort and Keereephet, Khlong Nueng, and Klong Phu waterfalls.
The nearest long-distance road transport is at Trat town, from where the {{convert|300|km|mi|abbr=on}} journey to Bangkok takes five hours by bus.
===Boat=== There are two ferry companies that run services from the mainland to Ko Chang. Both take vehicles and passengers. During high season, from November to May, there are passenger-only boat services from Ko Chang to the outlying islands of Ko Wai, Ko Mak, and Ko Kut. Boats do not run to outlying islands all year. They stop August / September times due to big seas and low season.
==Economy== Ko Chang's income derives largely from tourism, but some traditional livelihoods still exist. Many of Ko Chang's villages rely on fishing, with Ban Salak Phet ({{langx|th|บ้านสลักเพชร}}) being the largest and oldest community on Ko Chang, in a sheltered location in the south of the island. Other fishing villages include Bang Bao ({{langx|th|หมู่บ้านประมงบางเบ้า}}), at Bang Bao Beach, which consists of houses on stilts built into the sea, and Ban Khlong Son, which also partly relies on rubber plantations. Ban Dan Mai and Ban Khlong Non Si also have coconut plantations, and orchards of lychee trees. The variety of lychee grown, ''Silaman 200 years'', is believed to be found only on Ko Chang.
The first foreign backpackers started arriving on Ko Chang in the mid-1970s, using local fishing boats, when the island was still undeveloped. In 2019 tourism is the island's biggest earner. In 1982, Ko Chang along with the surrounding area became part of the protected Mu Ko Chang National Park, with approximately 85 percent of the island, together with nearby coral reefs, falling within the park.<ref>{{cite web|title=Mu Ko Chang National Park |url=http://www.dnp.go.th/parkreserve/asp/style1/default.asp?npid=211&lg=2 |website=Department of National Parks (DNP) Thailand |access-date=10 June 2015 |url-status=dead |archive-url=https://web.archive.org/web/20150610105756/http://www.dnp.go.th/parkreserve/asp/style1/default.asp?npid=211&lg=2 |archive-date=10 June 2015 }}</ref>
