Just got back from Colombia and man that place is awesome. Food was amazing everywhere, and cheap too. Travel expense was nothing (30km bus rides for ~$1.50). Beaches like you wouldn't believe. One beach near Santa Marta was by a bay that is fed by rivers coming down from volcanos, so the sand was fine obsidian and pyrite. It was black sand with gold flakes in it. Unbelievable. Que Rico!
