Scams
Scams targeting tourists occur. Card games are often involved. Some travellers have been taken to an automated banking machine and forced to withdraw money.
Travellers have been victims of scams and extortion at border crossings. Some have reported that border officials demanded they pay extra charges before allowing entry into Cambodia. In other cases, travellers were taken by strangers to isolated areas for extended periods of time where they were intimidated and pressed for payment. Carefully consider accepting assistance from individuals offering to help with documentation or transportation.
