Thai baht is as commonly used in Koh Kong City as US dollars and
Cambodian riel. US
dollars and Cambodian riel are accepted, but
generally speaking the tough exchange rate brings a poorer value for
your dollar or riel. Moneychangers are clustered around the main
market. Be careful to get the best exchange rate.
There is not much in the way of shopping
in Koh Kong except for the main market and a couple of convenience
stores, including the Pun Pun Mart on Street 3 and another in the
Asian Hotel on the riverfront.
Many of the hotels and guesthouses
catering to tourists offer free wifi these days. A couple of
restaurants do as well, including Cafe Laurent.
