The Bagan Archeological Zone:
New Bagan: Quieter than Nyaung U, but closer to the temples. Laid-back and home to Bagan’s best midrange accommodation and riverside restaurants
Old Bagan: Between New Bagan and Nyaung U, Old Bagan contains several of the main temples, restaurants, some shops, and the majority of the mid-range to top-end hotels
Nyaung U: A busy river town that attracts many independent travelers on a budget.
