Sukhothai — “the dawn of happiness” — was the capital of the first unified Thai kingdom in the 13th century. Today its UNESCO-listed Historical Park is a serene expanse of graceful seated Buddhas, lotus-bud chedis and lily-filled ponds, and for many travelers it is Thailand's most beautiful ancient city.

The walled heart of the old capital, where dozens of restored temples and monumental Buddhas stand among manicured lawns and mirror-still reflecting pools.

The spiritual centre of the kingdom, ringed by the distinctive lotus-bud spires that define the classic Sukhothai architectural style.

Flat, green and blissfully uncrowded, the park is best explored by bicycle — pedal between temples at golden hour when the light turns amber.
