This is a really great ride that can be done in about four hours. It's pretty much all sealed road. The ride leaves from Pakkred to avoid Bangkok roads. There and back in a day is doable, especially on a road bike, but we stayed a night at Tony's Place in Ayutthaya (marked on the Google Map), where they have rooms from 300 Baht and up. Thanks to Chris for the invitation, and Nichada Jacks for showing the way!
