Make sure you have enough gas in the tank, because Ayutthaya is worth making a detour for. Situated 25 miles from Sao Hai, it offers up some wonderful attractions, such as Ayutthaya Historical Park and Wat Phra Si Sanphet. Nothing says living large like a road trip does, so keep on driving to Bangkok. It’s 60 miles away and also has a few worthwhile sights, such as Khaosan Road and Pratunam Market.
