Contrary to the map information, the path is blocked by a locked gate because there is obviously private property behind it.

A perfect place for walking, cycling, or going with the family next to a beautiful lake and viewpoint on Lake Victoria. The place is private, however, you can check in the area for the possibility of going for a family picnic. The route is optimal for all types of vehicles. It is windy, and the weather is cold, it tends to rain after 2pm or get cloudy, highly recommended. See the ride on Youtube Bikers Costa Rica, as MTB Ride Lago Victoria (Several groups one ride)

There are still coffee plantations friendly to cleteros and this one that starts on Calle Cruces (on the way to San Francisco) is one of those. Get ready to find wide dirt and rubble streets, winding paths, technical descents and climbs (beginner and intermediate level)
