Are the land borders open for Cambodia yet? I need to do a quick hop as I am canceling my Non-B and WP and coming back on a regular entry stamp. Also, will I need a Cambodia visa to just do a "turn-around"?
TLDR : Answer Summary
Yes, Cambodia's land borders are open for entry. It is advisable to use a visa-run service to avoid potential re-entry issues. You will likely need a visa to re-enter Cambodia, which can be obtained at the border, costing around 1500 THB or $30. The Koh Kong border is a popular option for quick trips from Bangkok.
