Has anyone tried entering Burma at Ruili recently and getting a visa on arrival? I heard they've done it before but also that it got suspended at some point so if anyone has done it I'd be happy to get some info, also if you know what to bring and how much money they require you to carry on you as well as visa fees. Thanks.

Right now the border is closed.

If you want to go to Myanmar now you have to fly in.
And the Visa you can get easily here in Kunming.

Closed? I think if you get a visa arranged beforehand, with the right permits and guide (should be arranged from Kunming if possible) you can go in (at least exit China for Myanmar). I don't think visas on arrival are an option, or ever were an option for this crossing.

I hear a guide is also supposed to accompany all foreign visitors heading south of the border town of Mu-se until at least the town of Lashio, 8 hours south. Also, I doubt such a busy border crossing would be closed; the town of Mu-se is just an extension of China anyway and the vast majority of China-Myanmar trade flows through this crossing.

Get more information by contacting a Kunming travel agency and the Myanmar consulate here in Kunming.

I think going overland would be a fun experience, though after factoring in all the costs, it may be cheaper (if only slightly) to fly to Mandalay or Yangon, both of which can be reached from Kunming on non-stop flights. In fact, the only international flight departing and arriving at Mandalay airport originates in Kunming (China Eastern).
