Paramaribo is a fairly quiet city. There are a bit to see in the historic quarter, where you also find one of the best restaurants "Foto Baka" in the old fort.
There are several Casino's in the city and there tends to be a bit of nightlife around them, but they are also in noicy areas. Paramaribo is nice for a short stopover if you are on your way to the interior areas for more active holidays.
Various trips are available from the city to the interior. Worthwhile to go on fishing trips and nature tours.
