Bicycling is a very good and comfortable way to go around. You’ll see more than by walking and it doesn’t go that fast that you’ll miss everything around you. The movement on the bicycle will cause a slight breeze and will keep you cooler than you might think. You can stop everywhere for a drink or to make some beautiful pictures.
In and around many tourist destinations in Thailand it is possible to rent a bicycle or to book a guided tour. For example in cities of Bangkok, Pattaya, and Hua Hin. In the beautiful landscapes around Chiang Mai and Chiang Rai or between the beautiful ancient temples in the historical city of Ayuttaya and Sukhothai .
