Mainland India in the context of Cape Comorin (Kanyakumari)

The Andaman and Nicobar Islands is a union territory of India comprising 836 islands, of which only 31 are inhabited. The islands are grouped into two main clusters: the northern Andaman Islands and the southern Nicobar Islands, separated by a 150 km (93 mi) wide channel. The capital and largest city of the territory, Port Blair (officially Sri Vijaya Puram), is located approximately 1,190 km (740 mi) from Chennai and 1,255 km (780 mi) from Kolkata in mainland India. The islands are situated between the Bay of Bengal to the west and the Andaman Sea to the east. The northernmost point is 901 km (560 mi) from the mouth of the Hooghly River. Indira Point, located at 6°45'10″N and 93°49'36″E on the southern tip of Great Nicobar, is the southernmost point of India.

The territory shares maritime borders with Indonesia located about 165 km (103 mi) to the south, Myanmar located 280 km (170 mi) to the north-east and Thailand located 650 km (400 mi) to the south-east. The islands occupy a total land area of approximately 8,249 km (3,185 sq mi) with a population of 380,581 as per the 2011 census. The territory is divided into three districts: Nicobar, South Andaman, and North and Middle Andaman with the capitals at Car Nicobar, Port Blair and Mayabunder respectively.

Northeast India, officially the North Eastern Region (NER), is the easternmost region of India representing both a geographic and political administrative division of the country. It comprises eight states: Arunachal Pradesh, Assam, Manipur, Meghalaya, Mizoram, Nagaland, and Tripura (commonly known as the "Seven Sisters"), and the "Brother" state of Sikkim. North-east India is one of the most linguistically diverse regions in the world.

The region has India's international border of 5,182 kilometres (3,220 mi) with five neighbouring countries: China to the north, Myanmar to the east, Bangladesh to the southwest, Nepal to the west, and Bhutan to the northwest. It comprises an area of 262,184 square kilometres (101,230 sq mi), almost 8 per cent of that of India and has a population of 45,772,188, almost 4 per cent that of India. The Siliguri Corridor connects the region to other parts of India.

The Siliguri Corridor, often dubbed the "Chicken's Neck", is a stretch of land around the city of Siliguri in West Bengal, India. 20–22 kilometres (12–14 mi) at the narrowest section, this geopolitical and geoeconomical corridor connects the seven states of northeast India to the rest of India. The countries of Nepal and Bangladesh lie on each side of the corridor and the Kingdom of Bhutan lies at the northern end of the corridor. The Kingdom of Sikkim formerly lay on the northern side of the corridor, until its merger with India in 1975.

The city of Siliguri is the major city in the area and the central transfer point connecting Bhutan, Nepal, Bangladesh, Sikkim, Darjeeling, Northeast India and mainland India. According to the Indian Army, the Siliguri Corridor is the Army's strongest defensive line.

Kanyakumari (lit. 'The virgin Girl', referring to Devi Kanya Kumari, officially known as Kanniyakumari, formerly known as Cape Comorin) is a town and municipality in Kanyakumari district in the state of Tamil Nadu, India. It is the southernmost tip of the contiguous Indian subcontinent and the southernmost city in mainland India, and thus it is informally referred to as "The Land's End". Kanyakumari town is about 90 kilometres (56 mi) from Thiruvananthapuram and 20 kilometres (12 mi) south of Nagercoil, the headquarters of Kanyakumari district.

Kanyakumari is a popular tourist destination and pilgrimage centre in India. Notable tourist spots include its unique sunrise and sunset points, the 41-metre (133 ft) Thiruvalluvar Statue, and Vivekananda Rock Memorial off the coast. Lying at the tip of peninsular India, the town is bordered on the west, south, and east by the Laccadive Sea. It has a coastline of 71.5 kilometres (44.4 mi) stretched along these three sides.

Port Blair (pronunciation), officially named Srivijayapuram, is the capital city of the Andaman and Nicobar Islands, a union territory of India in the Bay of Bengal. It is also the local administrative sub-division (tehsil) of the islands, the headquarters for the district of South Andaman, and the territory's only notified town.

Port Blair is the entry point for the Andaman and Nicobar Islands. It is connected with mainland India by both air and sea. It is a two to three-hour flight from mainland India to Port Blair's Veer Savarkar International Airport and three to four days by sea to reach Kolkata, Chennai, or Visakhapatnam from Haddo Wharf in the city. It is home to several museums and the major naval base INS Jarawa of the Indian Navy, along with sea and air bases of the Indian Coast Guard and Andaman and Nicobar Police, as well as the Andaman and Nicobar Command, the first integrated tri-command of the Indian Armed Forces.

Mayabunder is a town and a tehsil in the northern part of Middle Andaman Island, Andaman Archipelago, India. The name is also spelled Maya Bunder or Maya Bandar. As of 2001, the county had 23,912 inhabitants, of which 3182 were in the town. It was settled in the British colonial period by immigrants from Myanmar and ex-convicts from Mainland India.

Administratively, Mayabunder is the headquarters of the North and Middle Andaman district, which is part of the Andaman and Nicobar Islands territory.
