The Nonthaburi Pier (pier N30) is the main gateway to Nonthaburi by river, a handsome wooden structure with a clock tower that serves the Chao Phraya Express Boat. Step off the orange-flag boat and you find yourself at a busy local market, surrounded by food stalls selling fruit, grilled meats, and noodle dishes.
The pier area is worth an hour in itself: the market, the clock tower, and the short ferry crossing to the temples on the opposite bank all start here. From the pier, Wat Chalerm Phra Kiet is a short ferry ride across the river. The area around the pier retains a provincial riverside character that contrasts with the Bangkok metropolis visible just downriver. Take the Chao Phraya Express from Chang Pier or Tha Tien in Bangkok — the last stop north.
