Stayed in a beautiful hostel on the cliff looking over Taganga Bay for a couple of nights. Taganga is a very low key fishing village just over the hill from Santa Marta, $1 bus ride to get there.
On the first night, we met some solvenia's at the hostel and went out for some drinks with them and met a really nice French couple. After the pub closed everyone just hung out on the street by the beach and some of the locals played guitars.
The next day, we walked over to the next bay, Playa Grande, to spend the day lounging around on the deck chairs and swimming.
