Note that all of the Colombian banks have offices here and ATM machines that accept foreign debit and credit cards paying out in COP (Colombian Pesos) at a rate close to what you would see on http://finance.yahoo.com/. The symbol is “cop=x”.

Near Bancolombia you can find guys on the street exchanging USD and EUR for COP and vice-versa.

The entrance and channel are straightforward and very well marked. You could easily come in at night, and if you are not wanting to anchor by the marina at night, you have a vast area of open spaces to anchor outside the marked channel until daylight. The anchoring area is on either side of Nene’s Marina, a tiny little thing but the channel directly in front and running parallel with the beach is 12-20 feet deep.
The marina has a Texaco gas station as part of it and diesel is available from a small adjunct of a dock to the west side of the marina. Diesel currently is 3.35 U.S. a gallon, the cheapest anywhere I’ve seen in over a year anywhere.

Clearing in you can call Rene Cadron on vhf16 16. Remember 12:00-2:00 everything is closed. Rene’s email is Serrana_agencia@hotmail.com.
The email given here in another post is incorrect and Rene asked me to let everyone know as much. His phone number is (57) 315 680 7980
I was charged 40.00 dollars for clearing in and out and paid on departure.
I was previously in Providencia and already had a tourist card so I don’t know what the fees would be for an initial clearance.

The entire area is under revitalization and is looking marvellous. There is now a huge public dock that is just east of the marina and services all the tourist boats. It is a u shape and the tourist boats use the inside portion, so if you are dinghing ashore just tie up on the outside sections. There are heavy bollards and hooks to tie to, security at night and the dock is 10 feet wide.

For garbage, turn left off the dock and walk down 20 yards and place your garbage off the strand in front of the jet skis. There is no container but the garbage gets picked up at night.

For provisioning, this is the place to do it.
There are no better prices in the Caribbean than here to take full advantage if you’re heading up to Caymans or Jamaica or Haiti.
To get to Super Todos, Supermercado, go left after leaving the dock to the traffic light, walk up to the first Street and go right and it’s down two blocks on the right.
It’s new, it’s well stocked and it has wines and liquors.

For shopping, it will take you weeks to go through all the stores.
I suggest going after the sun goes down as the whole area comes alive in the coolness of the evening. Turn right off the dock and a few blocks down are sidewalk cafes and artists open-air market.
If you keep walking down past the DeCameron Delphine, the whole area turns into a pedestrian mall, beach, restaurants and mega stores specializing in everything from perfumes to cigars to clothing etc.
The strand runs for miles in these parts and you could spend hours just people watching. The Internet is accessible on the strand.

Most stores will change your U.S. dollars. If you strike out keep asking.
Banks are not interested in exchanging money. There is a western union but it’s always busy and the wait long. Current exchange is 2700.00 to 1.
