I would certainly recommend a visit to Sunshine Orchid Farm, whether you love flowers or not – it’s hard not to appreciate the beauty of them. They include a famous variety of orchids, orchid derived perfumes, and plants that "dance to music" - out of this world!! I stayed at Jancondotel. It served as a good base to explore attractions in Udon Thani. Nong Pra Jak Park is only 5 mins across the road and is good for walking and reviving after a busy day.
