I guess you have already visited our island but will throw a little more information into this thread for any future readers.
Most boaters who come our way prefer Providencia to San Andres. The two islands are very different. San Andres is popular with low-end package tourism and caters mainly to the Colombian market. Development there has been haphazard and has sadly spoilt much of the island. Still, there are some very beautiful parts
of San Andres once out of the town centre.
Providencia is at the other end of the spectrum - very undeveloped, and sees only a trickle of tourists. Many visitors here are repeat visitors - lots of people who visit by yacht plan on spending a couple of nights and end up staying for a week or two as it's a magical place.
You can hire scooters of golf buggies to explore the island in a day. The scuba diving
is excellent in Providencia - the second biggest barrier reef in the Caribbean
is found just offshore
. I'm looking at it as I type this.....
I'd also recommend as visit to the McBean Lagoon
National Park while you are here. You can visit by kayak
or use your own dingy boat. Crystal clear calm waters and offshore
islands can be explored there. You might also want to go hiking or horseback riding through the islands forested mountains. Plus there are many undeveloped beaches and coves to explore.
