Situated 560km from Bangkok; Loei is one of Thailand's most beautiful and unspoiled provinces. The area is mountainous and temperatures can occasionally drop close to 0oC during the cold season, while summers are generally hotter than elsewhere in Thailand.
Loei is a good base if you wish to see something of rural life in Thailand.
Air conditioned buses from Bangkok's Northern Bus Terminal leave morning and evening. The journey time is about 10 hours. From Phitsanulok, in the north-east, catch a bus to Lom Sak where you can pick up the bus on to Loei. Total journey time takes about 6 hours.
There is a regular bus service between Udorn and Loei which takes about 4 hours.
Samlors and songthaews are readily available for journeys around town. If you want to travel further afield ask your hotel if they can arrange a car and driver for the day.
