La Coca Falls and Yokahú Tower
A roadside waterfall and a stone lookout from the 1960s, both easy stops.

The only tropical rainforest in the US National Forest System, an hour from San Juan, with waterfalls and tree frogs.
The road climbs from the coast into wet, green mountains, home to giant ferns and the tiny coquí frog, whose two-note call is the sound of Puerto Rico. Hurricane Maria stripped the forest in 2017, and it has grown back fast.

A roadside waterfall and a stone lookout from the 1960s, both easy stops.

A kayak tour through mangroves to a glowing bioluminescent lagoon. Book for a dark night.
