Coming from Santiago de los Caballeros

Follow the street leading into Mao until the first traffic light. Then turn right and follow the street until you reach its end, where you find the Fortaleza, a big green building. Turn right again. Stay on that street for a while until you get to the prison, a huge white complex with watchtowers. Just after it there is the entrance of Biotropic on the right-hand side. It is marked by a big escutcheon. Pass the sentry and keep going straight until you get to the parking lot.

 

Coming from Santiago de Rodriguez

Follow the street leading to Mao until you come to a crotch with a filling station with a huge Dominican flag. There head towards Mao but immediately after the crotch there is the entrance of Biotropic on the left.
