Udon Thani, although a reasonable size, does not have much in the way of family attractions, but there are a few places that are worth a visit during your stay. Most of the ‘big’ attractions are spread out across the Issan district which covers North East Thailand, and most of them are best accessed by car, or a decent motorbike, but definitely not a moped.
The top sites include some religious structures of course, with Buddhist Temples playing an important role in the lives of the indigenous Thai people, but there are some museums, animal parks and national parks that are all worth visiting. Some, if not most places are best visited with a native Thai, or someone who has an excellent command of the Thai language. Partly in order to find the attractions, and partly to get answers to any questions you may have about where you are visiting.
The Red Lotus Sea (although most of the flowers are more pink or crimson than they are red) is about 45km south east from the Udon Thani ring road, at Lake Nong Han on the banks of Ban Diam, in the Kumphawadpi Reserve. The beauty of the lake is best witnessed in the low season, between November and late February. The Red aquatic flowers begin to bloom in October, following the rainy season, reaching full bloom in December through to late January. The best time of day to visit is between 6.00am until around 10.00am. If the day is cloudy (as it was when I recently visited), a visit at any time should provide the best display as the blooms remain open when the sun is not bearing down on them.
