Adventure travel is a type of niche tourism, involving exploration or travel with a certain degree of risk (real or perceived), and which may require special skills and physical exertion.. According to the U.S.-based Adventure Travel Trade Association, adventure travel may be any tourist activity that includes physical activity, a cultural exchange, and connection with nature.
This may include activities such as mountaineering, trekking, bungee jumping, mountain biking, cycling, canoeing, scuba diving, rafting, kayaking, zip-lining, paragliding, hiking, exploring, canyoneering, sandboarding, caving and rock climbing. Some obscure forms of adventure travel include disaster and ghetto tourism. Other rising forms of adventure travel include social and jungle tourism.

Cultural tourism is a type of tourism activity in which the visitor’s essential motivation is to learn, discover, experience and consume the tangible and intangible cultural attractions/products in a tourism destination. These attractions/products relate to a set of distinctive material, intellectual, spiritual and emotional features of a society that encompasses arts and architecture, historical and cultural heritage, culinary heritage, literature, music, creative industries and the living cultures with their lifestyles, value systems, beliefs and traditions.
Cultural tourism experiences include architectural and archaeological treasures, culinary activities, festivals or events, historic or heritage, sites, monuments and landmarks, museums and exhibitions, national parks and wildlife sanctuaries, religious venues, temples and mosques. It includes tourism in urban areas, particularly historic or large cities and their cultural facilities such as theatres.
Cultural tourism is important for many reasons. On the one hand, it gives the local population the opportunity to benefit financially from their cultural heritage and thus to appreciate it and thus to preserve it and, on the other hand, it gives the visitor the opportunity to broaden his own personal horizons. Cultural tourism can therefore help to strengthen identities, improve intercultural understanding and preserve the heritage and culture of an area.

Entertainment tourism is to include any trips aiming to enjoy entertainment activities, such as concerts, musicals, medieval festivals, magic performance, circus, comedy, sport events, theatre, dancing, clubbing and theme park visit etc. Nowadays Entertainment attractions encourage tourists to travel around the world to have fun and are an important part of many gaming and entertaining destinations.

Is catering for tourists wishing to experience the natural environment without damaging it or disturbing its habitats. It is a form of tourism involving visiting fragile, pristine, and relatively undisturbed natural areas, intended as a low-impact and often small scale alternative to standard commercial mass tourism. It means responsible travel to natural areas, conserving the environment, and improving the well-being of the local people. Its purpose may be to educate the traveler, to provide funds for ecological conservation, to directly benefit the economic development and political empowerment of local communities, or to foster respect for different cultures and for human rights. Since the 1980s, ecotourism has been considered a critical endeavor by environmentalists, so that future generations may experience destinations relatively untouched by human intervention. Several university programs use this description as the working definition of ecotourism.

Spiritual tourism, religious tourism, sacred tourism, or faith tourism, is a type of tourism with two main subtypes: pilgrimage, meaning travel for religious or spiritual purposes, and the viewing of religious monuments and artefacts, a branch of sightseeing.
Religious sightseeing can be motivated by any of several kinds of interest, such as religion, art, architecture, history, and personal ancestry. People can find holy places interesting and moving, whether they personally are religious or not. Some, such as the churches of Italy, offer fine architecture and major artworks. Others are important to world religions: Jerusalem holds a central place in Judaism, Christianity, and Islam. Others again may be both scenic and important to one religion, like the Camino de Santiago in Spain, but have been adopted by non-religious people as a personal challenge and indeed as a journey of self-discovery. Religious tourism in India can take many forms, including yoga tourism; the country has sites important to Buddhism, Islam, Sikhism and Hinduism, as well as magnificent architecture and, for some travelers, the attraction of orientalism. Japan too offers beautiful religious places from Buddhist temples to Shinto shrines.

According to UNESCO, an internationally mobile student or an educational tourist is an individual “who has physically crossed an international border between two countries to participate in educational activities in a destination country, where the destination country is different from his or her country of origin”
Educational tourism could be referred to as an approach for pursuing education, carrying out research activities and knowledge acquisition. This sector is acquiring popularity these days and is a fast growing sub-sector in the travel and tourism industry. As far as academics are concerned, this sector has vast scope and is changing the dynamics of the sector constantly; it is more of a perspective type of tourism. Educational tourism is also called by other names such as job development, career enhancement or self-actualization experience. The idea is that apart from self-improvement, travel can be relaxation, learning can be more fun than ever and there is no age bar restricting people from learning by travelling (this does not include people who wish to travel for educational purposes but are unable to travel due to health problems).

Health tourism is generally defined as organized travel outside one’s local environment for the maintenance, enhancement, or restoration of an individual’s wellbeing in mind and body. Medical tourism is regarded as more organized travel outside one’s natural health care jurisdiction.
Common categories of procedures that medical travelers pursue during healthcare trips are orthopedics and trauma surgery, aesthetics and cosmetic surgery, cardiology or cardiac surgery, bariatric surgery, dentistry, cancer treatment and aftercare.
According to international statistics and facts over 7 million global citizens cross borders yearly to appreciate the benefits and advantages of health tourism. So the health tourism, which also includes medical tourism as a part of it, is like a gateway for medical tourists to receive affordable and cheaper healthcare without compromising on quality.
