One day
Start early by bicycle among the historical park — Wat Mahathat and the tree-root Buddha head, Wat Ratchaburana's prang, and the three chedis of Wat Phra Si Sanphet — before the heat and the coaches. Slurp boat noodles for lunch, rest through the hottest hours, then cross the river in the late afternoon to Wat Chaiwatthanaram for the sunset. End at the island night market for dinner and roti sai mai.
