Overview
La Mina Trail is the most visited trail in El Yunque National Forest and one of the most popular waterfall hikes in the Caribbean. The 1.9-mile out-and-back route follows La Mina River through the lower tabonuco forest: the mature, broadleaf tropical forest dominated by the tabonuco tree: to a 35-foot cascade that drops into a clear, swimmable pool.
The trail's popularity is earned. The falls are genuinely impressive, the river is beautiful throughout the walk, and the tropical forest canopy creates an experience that has no equivalent on the continental United States. The timed entry permit system (as of 2026) reduces but does not eliminate crowds: early arrival remains the best strategy.
The Route
Miles 0.0 to 0.5: El Portal to River
From the El Portal Recreation Area visitor center, the trail descends south into the forest and joins the La Mina River corridor at mile 0.5. The tabonuco forest closes overhead almost immediately: the canopy is dense, the air is humid and cool compared to the coast, and coqui frog calls are constant background sound.
Miles 0.5 to 0.95: River Trail
The trail follows the river closely on the east bank, crossing on stone bridges at two points. The river runs over smooth boulders in a series of small cascades and clear pools. Many visitors stop at the swimming holes along the river before reaching the main falls. The trail ends at the pool below La Mina Falls.
La Mina Falls
The falls drop 35 feet over a smooth rock face into a pool roughly 20 feet in diameter. The pool is deepest near the falls: swimmers should approach carefully as the current can be strong after rain. The surrounding rocks are moss-covered and photogenic. This is the turnaround point; return the same way.
When to Hike
December through April: Dry season brings better odds of clear skies and a less muddy trail. Morning starts before 9 a.m. give the best experience before crowds build.
May through November: Wetter season with possible afternoon thunderstorms. The river can rise quickly after rain. If the water looks notably higher or faster than normal, do not enter the pool.
Year-round: El Yunque has no off-season in the conventional sense. Coqui frogs call every night of the year, and the forest is green in every month. Rain jacket in a daypack is standard preparation.
What to Bring
A lightweight rain jacket, even on clear mornings. Water shoes or sandals for the river pool. Sunscreen for any open sections. Water from El Portal (facilities are at the visitor center). The trail is short, so a full hydration pack is not necessary: a water bottle is sufficient.
Trailhead Access
Trailhead access requires a timed entry permit for El Portal Recreation Area, booked through Recreation.gov (as of 2026). Flush restrooms and water at El Portal visitor center. Dogs are not permitted in the forest. No separate trail permit required beyond the El Portal entry.
Nearby
The Big Tree Trail starts near El Portal and is an easy loop through mature tabonuco forest: a natural pairing with La Mina. The El Yunque Trail climbs higher for summit views for those who want more vertical. Always review Leave No Trace principles: the pools and riverbanks at La Mina are fragile tropical ecosystems.
