The fastest way to get from Uruguay to Argentina is by boat. The countries are separated by Rio de la Plata, the estuary formed by the confluence of the Parana and the Uruguay Rivers when entering the Atlantic Ocean. The fast way is to cross directly from Montevideo, but the best option is to make a detour to Colonia del Sacramento. As there are only 50 Km between the two cities, the trip to Argentina lasts about an hour and a half (with the fast boat) and the ticket costs around USD50.
The old center is included in the Unesco World Heritage.There is a church, a lighthouse, some museums, some beautiful houses, the fortress walls etc. It’s very nice, but is a couple of hours you’ve seen everything there is to see. It’s nice to stop for a coffee, a mate or to grab lunch in one of the many restaurants you’ll find in the old center. I particularly like the way in which nature takes over the old walls: roots, leaves and flowers spread over the walls and the streets, creating perfect images.
Outside the old town there isn’t much to see, aside from bohemian neighbourhoods with nice restaurants and the promenade by the river. But away from the center, hidden from the tourists, you can find the old bull ring in Plaza de Toros. It’s closed to the public, but I think one can find a way to cross the fence to take a look inside.
What I like most about Colonia is the fact that the city center slowly transforms jnto a sort of village without sidewalks, formed of small houses with generous gardens. It reminded me a lot of some cities in the romanian mountains.
