According to wikivoyage, there are 4 open border crossing points between Myanmar and Thailand. Our first idea was to cross the "Three Pagoda Pass" near Kanchanabury but it say that it's not open for foreigners now. So, as we wanted to visit Mergi islands, the closest pass is Kawthoung/Ranong but seems that the road between Myeik and Kawthoung is a bit difficult.
Our trip is in August.
So the question is: it's better to go back to Mae Sot pass or do we have any chances to get to Kawthoung and cross?
