### Northern section

The highway begins at PR-955 in the community of Palmer in the municipality of Río Grande. From there, it climbs into El Yunque National Forest 4 km from its beginning. Inside the forest, the road is concurrent with Forest Highway 191 and many of the forest's major attractions are along the route. At 7.8 km is the Las Cabezas Observation Point and at 8.1 km is La Coca Falls where an access gate prevent traffic on PR-191 beyond that point from 6:00 PM to 7:30 AM. The route continues past the Yokahu Tower (8.8 km) and Baño Grande, Baño de Oro, and an information center (11.7-11.9 km). The road is closed to public traffic through part of the forest starting at a point 13.1 km from the beginning in Palmer and immediately past PR-191's second junction with PR-9938 (which is signed "Ramal 938") and just before a junction with Forest Route 10 and near the Mount Britton and El Yunque Peak trailhead.
