Thailand is a country of many contrasting facets, with glorious beaches as well as forests, jungles and mountains. Whether you want to swim, sunbathe or explore the wildlife, a family holiday in Thailand will never be dull.If you're looking for seaside relaxation, visit the beaches and bay of Hat Karon in Phuket with sand dunes and palm trees. The island of Ko Tao has coral reefs and is the place to go if you want to learn to dive, but you can also go mountain biking or just sunbathe on the beach. The Royal Barge National Museum in Bangkok houses several barges built for Thailand's kings; the beautifully detailed carving is quite breathtaking. Doi Suthep-Doi Pui National Park in Chiang Mai has a wealth of flowering plants and ferns as well as three hundred species of birds. If you're in the mood for a quiet spot, try the town of Sangkhlaburi; from there you can set off on an elephant trek or jungle tour. For mountains and forests, visit the north-western province of Mai Hong Son.
