Well, Robert closed the comments on the 'Cambodia crossings'
And Tod mentioned that there are 40 crossings in Sa Keow. I just wanted to add that there are probably hundred's, if not thousands, of border crossings into Cambodia for Thais, most of them actually illegal though! #noonegivesashititsbusinessasusual
TLDR : Answer Summary
The discussion highlights the numerous border crossings from Thailand into Cambodia, with a note that many of these crossings are illegal for Thai citizens. Commenters express concern about the lack of information for foreigners regarding legal crossings, specifically mentioning well-known points such as Chong San Ngam, Aranyaprathet, and Hat Lek, while questioning the process for visa stamps on illegal crossings.
