Rail Trail: Walk with biologist Chabert along Royal Isabela’s historic train line — choose a 2- or 5-mile route (groups up to 12).
Embark on a compact, immersive hike led by on-site biologist Chabert along Royal Isabela’s historic train trail. You can opt for a leisurely 2-mile stroll or a more immersive 5-mile hike that moves through rolling pastures, lush secondary forests and winding paths that finish at the ocean’s edge. The walk follows remnants of the old railway that once connected Isabela to the Guajataca Tunnel and threads habitats where the rare Atlantea tulita butterfly, abundant birdlife and the hush of the jungle punctuate the trail.
Highlights
Outing Highlights
Two ways to explore: a short stroll or a full coastal hike
Choose a 2-mile option for a relaxed walk or stretch to a 5-mile route to reach coastal vantage points. Both follow the line of a former railway, moving from sunlit pastures into shaded forest before opening onto the ocean.
Rare butterflies and attentive birdlife
The trail passes through habitat where the rare Atlantea tulita butterfly can be encountered; bird calls and other forest sounds are a constant companion as the path moves through secondary forest and edge habitats.
Railway remnants that trace a vanished connection
Walk along vestiges of the old railway that once linked Isabela to the Guajataca Tunnel, a tangible thread of local history woven into the landscape as you move between pastures, forest and shore.
