Okay here is the flip side of my question from the other day. What do I need to do to be able to enter Laos? Is it a whole application process like for coming here? I would assume so but the locals act like I am crazy for not just walking down to the ferry to go across.
TLDR : Answer Summary
To enter Laos from Thailand, travelers need to present proof of vaccination or an ATK antigen rapid test taken within 48 hours. A visa may be obtained beforehand or on arrival, depending on the traveler's nationality. Additionally, returning to Thailand may require COVID insurance and registration on ThaiPass. Note that ferry crossings may have specific limitations, so verify the location and services available.
