Thailand's temples - known as wats - are big, richly decorated and contain an interesting assortment of treasures. Every town has a large assortment of temples, with perhaps the highest concentrations in Bangkok, Chiang Mai and Ayutthaya. Some temples not to be missed are Wat Arun on the Chaopraya river in Bangkok, Wat Po, also in Bangkok and Chiang Mai's Wat Benchamabophit. Whilst in Chiang Mai, climb Doi Suthet to see Wat Doi Suthep, which offers stunning views over the area.
As well as spectacular scenery, Thailand's islands and beaches offer a good opportunity to take part in diving and snorkeling, the clear blue water offering glimpses of colourful coral and fish. Koh Tao is rapidly becoming the most popular island for diving and snorkelling, whilst Koh Phi Phi and Phuket are also popular. Other water ports available include sailing and windsurfing. At many places, bungee jumping and rock climbing are the order of the day, whilst paintballing offers a good opportunity to let of some steam.
Thailand has some beautiful golf courses, some designed by skilled international golfers. Muay Thai is the national sport and no trip is complete without watching a match or even training and competing yourself.
The amazing landscape makes Thailand a great place for walking and trekking, the hill tribe villages to the north making a great stop over or a three or four day trek.
Many come to this deeply spiritual country to learn about meditation, and there are numerous meditation courses available. Whilst here, you can also learn the ancient art of massage or join yoga classes on the beach.
Thai food is some of the best in the world, and you will find some outstanding restaurants, offering everything from international style dining, dining aboard river cruises or simply eating at a tiny table on the street.
The spas and saunas are also a great place to unwind and be pampered; whilst for many cosmetic surgery and cosmetic dentistry provide the opportunity for self improvement. Also, there are plenty of chances to indulge in a little retail therapy.
Thailand has a great selection of outdoor markets, floating markets, stores and shopping centres. Do not miss Bangkok's Chatuchak market, MBK, Paragon or the night bazaar at Suan Lum, whilst Chiang Mai's Night Market draws visitors from all over the world.
For people wishing to take in some culture there are some interesting museums, art galleries, exhibitions and displays of Thai dancing. Thailand also has some interesting theme parks, shows and zoos such as Sri Racha Tiger Zoo.
There is always something to see and do in Thailand, and the numerous festivals can add colour and life to your holiday, especially if you are lucky enough to be in the country during Songran or Loi Krathong.
There are plenty of opportunities to get in touch with nature in the national parks, such as Khao Yai where parts of the movie The Beach was filmed or Koh Samet, where the outstanding natural beauty has led to its being preserved as a national park.
Whatever you decide to do, there never seems to be quite enough time, and it is almost certain that Thailand's charms will draw you back time and again.
