Ilha Grande, Brazil

Another day, another trail run. This time 17km to the beach called Dois Rios, which has a deserted prison and town along the coast.
A perfect 2.5km uninhabited beach, accessible only by ferry or trail. I woke up early and ran the steep 7km from town, in order to catch the beach with no tourists. With the hike back, it worked out to a 18km day.
Just off the coast of Rio is the protected island reserve of Ilha Grande. No cars allowed, only accessible by boat and covered in trails leading to perfect beaches.
