I am wondering which crossings to Myanmar that I can do the $10 usd 1-day pass and recieve 30days on arrival upon return using 1 of my 2 yearly land crossings into Thailand.

I know of mae sai, mae sot, and not sure what the name of the one in ranong is.

Heard there are 1 day passes to take a boat in ranong to cocks comb island, Myanmar.

Does anyone know if I can get 30 days on arrival upon return to Thailand from cocks comb island. I am correct to assume the water crossing is treated as a land crossing?

Thanks!
