An absolute privilege to visit this region. Wonderful sights, river trips and trekking. And very friendly people! Yes travel still has some unexpected adventures!
Mrauk-U is a city itself has several interesting sights, Cycling for a day and a boat rip with 2 or more people is a good thing to do.
In most places in Myanmar people are open and friendly. Experienced difference in Mrauk-u.. People generally very reserved, less welcome towards tourists. Some exceptions are there..
Mrauk U is in its infancy as a tourist site. GO NOW - for the adventurous, you will have access that you won't have in five years.
It is much much smaller than other temple cities you will see in South Easy Asia, but as it was the capital for five hundred years (roughly), you see different Buddhist traditions coming together. It is fascinating. I hope to go back.
If you do make the long journey to Mrauk U, do yourself a favor and walk around the city and get lost.
Doing so you will meet so many extremely friendly and curious locals. While many of the locals do not speak English, they will be so fascinated in you. If you have a camera, expect many children to "ask" for you to take a photo of them by pointing at the camera and then themselves. The history here is incredible as well, but the locals made my trip here a great experience. I would love to come back here.
Go now! It is still unspoilt as are the local people who make you welcome. Bagan was like this once!
