Going to Colonia was kind of a last minute decision for me. I wanted a quick (and cheap) weekend get away that would allow me to reflect on my time in South America, and Colonia gave me just that. I took the Colonia Express Ferry from Buenos Aires and in less than 2 hours arrived in Uruguay and rented a bike from there. Colonia is an amazing little town that I would definitely recommend for a day or two!
El Viajero - Great space and met some amazing people during my stay here. The staff wasn't great, but for a night or two that doesn't really matter as long as the sheets and room is clean!
Pizzería Don Joaquín - Great pizza, right next to the hostel, and accepts credit card!!
A la Pipetúa - The cutest little restaurant tucked away on the coast of the city. Incredible palle! Only accepts cash though.
Bocadesanto - This is the cutest little place that I cannot recommend enough. It is very secluded, but such a gem. It's a burger/bakery which is a great enough combo to begin with, that has a wonderful service, cute atmosphere and beautiful rooftop if you're lucky enough to see it.
Definitely rent a bike for the weekend, it's a beautiful ride throughout the town. There is also an old bull fighting arena (pictured left) that is well worth the ride out of town for, if you're up for an adventure.
