In the area of Las Matas de Farfán there is a sulphurous spring, La Zurza, which is highly visited by regional tourism.

The resurgence of the town of San Juan occurred in 1733, according to Carlos Esteban Deive in his book Las emigraciones Canarias a Santo Domingo.

In this sense, this author says that the resurgence of San Juan "allowed the gathering of all the ranchers and farmers who lived scattered throughout the valley, who were joined by some neighbors from Azua."

With regard to the population contribution of this last region, it is important to point out that after the earthquake of November 1751, families left to live in the San Juan Valley.

San Juan produces more than 90% of the beans, 84% of the peanuts, 31% of the corn, 35% of the pigeon pea, 20% of the onion, and 36% of the sweet potato consumed by the Dominican population.

The growing dairy farming is the other economic activity that the region has developed, its milk is extracted and used to make different varieties of cheese and yogurt.

In addition, there is currently a private local company Explomarca S.A., which extracts Travertine in La Trinchera, San Juan province.

Another source of income for residents are the various formal and informal businesses such as bakeries, tailors, clinical laboratories, medical offices, pharmacies, a market, hotels, galleries, bars and activities that have to do with transportation services, among others.
