“The secret to Santa Marta is to use it for what it does well: hotels, restaurants and bars, and then get out to the slew of superb nearby destinations during the daytime.” – Lonely Planet
Ciudad Perdida Trek (The Lost City Trek) – I opted to pass on this because of the heat and mosquitoes plus my budget only allowed for a few big treks and this was not one of them.
Tayrona 2-3 Days (2 days 1 night was good for me)
Minca can be a day trip or up to a few days
Lost Trek is 4-5 days plus at least a day before departure
Plus however much of the city and the beaches you want to see
