Colombia has basically everything what a traveller is looking for; beautiful beaches, mountains, city life and much more. As an expat living in Colombia I would like to recommend some places that you should visit in Colombia
The "jacuzzi's" of Quebrada Las Gachas, Santander. You like bathing, but the Hotel pools are to crowded for your taste? In Santander you can bathe in a natural little jacuzzi pool and enjoy the quiet nature Setting around.
