What are the options for a border run from Krabi to Ranong and is it feasible?

Terrible bus ride from krabi to Ranong , ferry terminal is at immigration , Ranong , I went January 10 2020 , remember well lol was my 50 th birthday , I had no problems then , Thai immigration stamped me out and officer told me to make sure I was back before 4 o’clock , obviously doing border bounce , no problem , my girlfriend stayed in Ranong went shopping , . Paid 300 baht I think , can’t remember maybe cheaper but my Thai not great and lady shopping , Thai guy put me on long tail with couple of French backpackers and Burmese workers , middle of trip you stop at island , Burmese had to get of , we stayed on board , but boatman took our passport and copies I think , everyone get back on and head Myanmar , stop , get of long tail , was asked when back I said few hours , through little office , hand over passport and crisp 10 dollar , ps there’s a god chance of getting slightly wet on long tail so be aware , , oh and falling in at piers , your climbing over boats to get to land , could have turned straight around and come back , but hey , met little street urchin , spoke loads of languages , got duty free cigarettes , told him I wanted beer , he took me shop , I took him bar next to immigration , had 4 beers each , I paid , cost me about 100 baht and that included tip for lady at restaurant , , probably walked no more than 200 meters in Myanmar , absolute easy , you don’t actually get a visa for Myanmar as you can’t travel , much further . Tipped my guy , but you know enough now so your call be he was great , spoke his own language and a good few others , great source and good fun , , . Well sorry so long but when I went I was flying blind , always good to have as much information as possible , can’t see it would have changed much as it’s the way the mynamese get into Thailand for work , on way back repeat little island , got back Thailand in probably 4 hrs , immigration officer stamped me in , wished me happy birthday , very easy . But bus Ranong to krabi long and slow , and I mean long 7 hrs of bad roads , no problem for me but lass Very unhappy , .

u can stay up to 14 days in Burma but cant travel more than 20 kms from Town

.Pre covid a seat in a boat was 100 baht ( 50 if you speak Thai) or the full boat 500

Ranong is a good option. You will need two copies of your passport and a crisp US $10 note for the other side. You negotiate for a long tail ride and takes about 40 minutes each way. You’re in Myanmar for about 10-20 minutes depending on whether you want duty free or not.

If you want to know about Ranong then ask in the koh Phayam Facebook page.

You say you've already done 2 border bounces. If you entered without a visa at a land border 2 times in 2023 already then you're at the limit. You can only enter visa exempt (without a visa) 2 times per calendar year at a land border.

If you've already entered twice you'll either need to do a border bounce by air, or you'll need to travel to a Thai embassy in Malaysia and apply for a tourist visa or other visa in order to be able to return.
