Did La Ruta a few years ago.
We were told only to leave the hotel in San Jose in groups and not to go out on our own, there were plenty of single american men around (not doing the race), one sat down next to us at the bar and extolled the virtues of being able to “get a young girl easily” in San Jose.
The start town of Jaco beach was equally sleazy, no shortage of prosititutes.
The rest of the country was amazing, the Costa Ricans we met were rhe most friendly, welcoming bunch. The scenery was breathtaking and the support from the locals was fantastic.
The last day was interesting riding through the slums allongside the rail tracks, we had armed guards at one point and a couple of the costa rican riders got mugged.
This was 2007.
