It has three wildlife sanctuaries; Pushpagiri Wildlife Sanctuary, Talakaveri Wildlife Sanctuary and Brahmagiri Wildlife Sanctuary, one National Park; the Nagarahole National Park and the only private sanctuary of India; the SAI Sanctuary.

Kodagu is home for species endemic to the Western Ghats. It has large tiger and elephant populations as well. As per the elephant census of 2023, Kodagu with 1,013 elephants, had nearly one-sixth of total elephant population in Karnataka, second only to Chamarajanagar.

Economy of Kodagu is dependent on agriculture. Major crops grown here are Paddy, Coffee, Rubber, Pepper, Cardamom, Coorg Oranges and Honey production. Tea, Ginger and Cocoa are also grown in smaller quantities.

Kodagu is the largest Coffee and Pepper producing district in India. Karnataka produces nearly 70% of the total Coffee production in India, out of which 33% is contributed by Kodagu district alone. Also Kodagu produces nearly a quarter of India's Black Pepper.

Two members of the legislative assembly are elected from Kodagu to the Karnataka Legislative Assembly, one each from the Madikeri and Virajpet. Dr. Mantar Gowda represents the Madikeri constituency while A.S Ponnanna represents the Virajpet constituency; they are from the Indian National Congress. Kodagu, formerly part of the Kodagu-Dakshina Kannada (Mangalore) constituency, is now part of the Mysore-Kodagu Lok Sabha constituency parliamentary constituency. The current MP for this constituency is Shri Yaduveer Krishnadatta Chamaraja Wadiyar, from the Bharatiya Janata Party.

The Codava National Council and Kodava Rashtriya Samiti are campaigning for autonomy to Kodagu district which would have made Coorg more prosperous and independent.

The Kodavas were the earliest inhabitants and agriculturists in Kodagu, having lived there for centuries. Kodavas being a warrior community as well, they carried arms during times of war and had their own chieftains.

The earliest mention about Coorg can be seen in the works those date back to Sangam period (300 BCE - 300 CE). The Ezhimala dynasty had jurisdiction over two Nadus - The coastal Poozhinadu and the hilly eastern Karkanadu. According to the works of Sangam literature, Poozhinadu consisted much of the coastal belt between Mangalore and Kozhikode. Karkanadu consisted of Wayanad-Gudalur hilly region with parts of Kodagu (Coorg).

The Haleri dynasty, an offshoot of the Keladi Nayakas, ruled Kodagu between 1600 and 1834. Later the British ruled Kodagu from 1834, after the Coorg War, until India's independence in 1947. A separate state (called Coorg State) until then, in 1956 Kodagu was merged with the Mysore State (now Karnataka).

In 1834, the East India Company annexed Kodagu into British India, after deposing Chikka Virarajendra of the Kodagu kingdom, as 'Coorg'. British rule led to the establishment of educational institutions, introduction of scientific coffee cultivation, better administration and improvement of the economy. This reference notwithstanding - we should remember that the colonial rule by the British in India was about exploitation of resources and Kodagu provided a lot of scope for economic benefits to a colonising empire.

A huge minority of Muslims dot the Coorg district, especially the towns of Kushalnagar, Virajpet and Mercara. A sizeable of them are the Nawayaths who shifted in the eighties from Bhatkal and Murdeshwar in order to pursue coffee & arecanut plantations and textile business. The numerous mosque dotting the landscape is the testimony of Muslim presence in the district.

A small number of Mangalorean Catholics are also found in Coorg. They are mostly descended from those Konkani Catholics who fled the roundup and, later, captivity by Tippu Sultan. These immigrants were welcomed by Raja Veerarajendra (himself a former captive of Tippu Sultan, having escaped six years of captivity in 1788) who realising their usefulness and expertise as agriculturists, gave them lands and tax breaks and built a church for them.

Are Bhashe, a dialect of Kannada, Tulu and Kodava language are native to Kodagu district. Kodava Language uses the Official Script Invented by Dr IM Muthanna in 1970.

According to Karnataka Kodava Sahitya Academy (Karnataka's Kodava Literary Academy), apart from Kodavas, and their related groups, the Amma Kodavas, the Kodava Peggade (Kodagu Heggade) and the Kodava Maaple (Kodava Muslims), 18 other smaller-numbered ethnic groups speak Kodava Takk in and outside the district including the Iri (Airi, or the carpenters and the village smiths), the Koyava, the Banna, the Kodagu Madivala (washermen), the Kodagu Hajama (barber, also called Nainda), the Kembatti Poleya (household servants and labourers) and the Meda (basket and mat weavers and drummers).

Among other Kodava speaking communities are: the Heggades, cultivators from shimogga; the Kodava Nair, cultivators from Kerala State; the Ayiri, who constitute the artisan caste; the Medas, who are basket and mat-weavers and act as drummers at feasts; the Binepatta, originally wandering musicians from Malabar, now farmers; and the Kavadi, cultivators settled in Yedenalknad (Virajpet). All these groups speak the Kodava language and conform generally to Kodava customs and dress.

Less frequent are Tulu speakers Billavas, Mogaveeras, Bunts, Goud Saraswat Brahmins.

The Arebhashe gowdas, or Kodagu Gowdas, and Tulu Gowdas, are an ethnic group of Dakshina Kannada and Kodagu. They live in Sulya (in Dakshina Kannada) and in parts of Somwarpet, Kushalanagar, Bhagamandala and Madikeri. They speak a language known as Arebhashe a dialect of Kannada. Guddemane Appaiah Gowda along with many other freedom fighters from different communities revolted against the British in an armed struggle which covered entire Kodagu and Dakshina Kannada. This was one of the earliest freedom movements against the British called "Amara Sulliada Swantantrya Sangraama" (Amara Sulya Dhange formally called the 'Coorg Rebellion' by the British) started in 1837.

Kodagu is rated as one of the top hill station destinations in India. Some of the most popular tourist attractions in Kodagu include Talakaveri, Bhagamandala, Nisargadhama, Abbey Falls, Dubare, Nagarahole National Park, Iruppu Falls, and the Tibetan Buddhist Golden Temple.

• Talakaveri is the place where the River Kaveri originates. The temple on the riverbanks here is dedicated to Lord Brahma, and is one of only two temples dedicated to Brahma in India and Southeast Asia. Bhagamandala is situated at the Sangama (confluence) of two rivers, the Kaveri and the Kannika. A third river, the Sujyothi, is said to join from underground, and hence this spot is called the Triveni Sangama. Iruppu Falls is a sacred Kodagu Hindu spot in South Kodagu in the Brahmagiri hill range. The Lakshmana Tirtha River, with the waterfalls, flows nearby and has a Rameshwara temple on its banks. It is said that this sacred river was created when Laxmana, prince of Ayodhya and younger brother of Lord Rama, shot an arrow into nearby hill, the Brahmagiri hill. Chelavara falls and Thadiandamol peak are also in South Kodagu. Nagarahole is a national park and wildlife resort.
• Madikeri is the capital of the district and Raja's Seat park is popular with tourists. Kootu Poley dam is also popular among tourists. Omkareshwara Temple is a beautiful temple built in the Indo-Sarcenic style in Coorg. A legend is associated with the temple, built by Lingarajendra II in 1820 CE. The king put to death a pious Brahmin who dared to protest against his misdeeds. The spirit of the dead man began to plague the king day and night. On the advice of wise men, the king built this temple and installed a Shivalinga procured from Kashi, North India. St. Mark's Church is located within the Mercara Fort and was raised in 1859, by the officers and men of the East India Company. The building was funded by the Government of Madras, and placed under the Church of England in India, Diocese of Madras. The Church was closed after Indian independence, and taken over by the Government of Karnataka in 1971. The building now houses the Madikeri Fort Museum, managed by the Karnataka State Archaeological Department.
• Dubare is mainly an elephant-capturing and training camp of the Forest Department at the edge of Dubare forest; on the bank of the river Kaveri along the Kushalanagara – Siddapura road. Nisargadhama is a man-made island and picnic spot near Kushalanagara, formed by the river Kaveri. The Tibetan Buddhist Golden Temple is at Bylakuppe near Kushalnagara (Mysore district), in the Tibetan refugee settlement.
