Hoi An is built in a maze of rivers and estuaries, with the actual ocean beach just down the road. We took the evening 30 minutes cruise, which involves walking down a shockingly rickety gangplank and riding around with about 300 other boats poled/paddled by people who do not have their captains licenses. The four of us felt a little awkward as the 90-lb grandmother heaved on her oar. Even so, very relaxing and pretty.
Toward the end of the ride, you float these little lanterns away for good luck.
A couple of days later, our hotel desk lady suggested we skip the usual taxi and take a boat ride into town.
Another rickety boarding experience, but a really pleasant ride into town.
