Travel in developing countries provides incredible benefits to adventurous families, while at the same time offering considerable challenges. Families get to experience how other people live in cultures and circumstances very different from their own, and to experience wildlife and geographical wonders first-hand.

Wildlife and its habitats in developing countries are becoming increasingly popular attractions for international tourism. Many of the richest areas, biologically, are in the developing world. Growing numbers of ecotourists are flocking to the mountains of Nepal and Madagascar, the tropical forests of Costa Rica and Thailand, and the beaches of Belize and Sri Lanka. Nature tourists bring with them money to spend, money that creates jobs and incomes for households and communities in and around national parks and other protected areas.

Ecotourism enterprises tour agencies and guide services, lodges and private reserves as well as such satellite activities as crafts industries and transportation and food services, also generate revenues and foreign exchange. Governments can use this income in operating and protecting natural habitats.

Travellers who plan to visit developing countries and those embarking on prolonged vacations or arduous treks should take a number of precautions. A visit to the doctor is very important in preparing for travel in developing countries.  Third World traveller should have a thorough check-up and prepare for any health contingency at least eight, and ideally 10, weeks before the trip. They should obtain a brief summary of their medical histories to take with them, including the list of drug allergies. They should also prepare a list of medications they normally use, noting all trade and generic names as well as dosages.

Third World traveler should also keep some water and food precautions. Water is one of the main sources of infection. Boiling water is the best method for eliminating infectious agents. There is some debate about how long to boil, but bringing the water to a good boil for at least a minute generally renders it safe to drink.  Make it a habit to drink only bottled water that comes with a sealed cap. Drink only name-brand soft drinks, sterilized milk that comes in the long-life containers, and hot beverages that you know have been boiled.  You should not drink fruit drinks, fresh milk, or water in open containers. Carry water purification tablets, which you should use faithfully when in doubt. Ice cubes are definitely a no-no.

Heated food should be hot to the touch and eaten promptly. All hot foods must be freshly prepared in front of you, not previously prepared and left to sit. Plates and silverware must be clean and dry.

Westerners traveling to developing countries are often targets of criminals around the world because they must obviously travel with money and most likely with a lot of money. So, avoid being a target. Avoid crowds where you have to slow down. Every time you slow down while walking in a street you become an easier target. Be aware of who is behind you. If the same person is behind you for a few minutes, be suspicious. Avoid traveling with big luggage. The bigger the luggage, the more visible you are and the harder it is for you to defend yourself, chase a thief, etc. Backpacks can be easily opened even while you are walking.
