I recently started making hand-drawn dungeon maps again and here is one for you to use. The map is about a semi-hidden cave that is being used by local smugglers or thieves to gain a clandestine entry into the city. Room 1 has a very small opening to the sea/river (or even a lake, whichever body of water you prefer) to spot both incoming shipments and to get an advance warning on possible hostiles. There den is not often deserted and you can usually find at least a couple of unsavory characters inside.
In DnD 3e/Pathfinder terms this location would best serve levels before 5, since it has limited space and tactical depth for higher level characters.
