Planadas-Yeyesa Nature Reserve

The reserve is located close to the famous Cerro Las Tetas (officially Piedras del Collado).

Two of the most prominent features of the reserve are Cerro Planada, a 2,480 feet (755 m) high mountain peak, and La Yeyesa, a heavily forested canyon formed by the Lapa River and other streams which feed into the Nigua River.

[1] La Yeyesa can be accessed through a lightly trafficked yet moderate trail.

The forest area is also home to the endangered Puerto Rican boa.

In addition to its biodiversity, the reserve is home to several caves, such as El Ceto and La Iglesia Caves, which are home to indigenous Taíno petroglyphs.
