Trujillo Alto is a green town in the hills just south of San Juan, next to a big lake that gives the area its fresh water. It is a calm, family-friendly place surrounded by nature.
You can enjoy the calm Carraizo lake, hike shady trails in the hills, and cross the historic old bridge over the river.
Carraizo lake sits among green hills and helps supply water to the city, while birds and fish make their home along its shores.
An old stone-and-metal bridge from long ago still stands over the river and reminds everyone of the town's past.
