Playa Flamenco to Tamarindo Beach Military Track
Navy bombing range roads to hidden Caribbean paradise
This forgotten military road cuts across Culebra’s wild eastern peninsula, connecting the famous white sands of Playa Flamenco with the secluded coves of Tamarindo Beach. Built by the Navy during decades of bombing practice, the track winds through dense scrubland punctuated by rusted warning signs in Spanish and English. You’ll navigate around unexploded ordnance markers and crumbling concrete bunkers while dodging low-hanging limbs that scratch paint and test your spotting skills on every turn.
High-clearance 4WD essential for the rocky creek crossings and eroded sections where rain has carved deep ruts. The route requires careful navigation—GPS signals bounce off the surrounding hills, and several unmarked forks can lead to dead ends at cliff edges. Plan for a full day including beach time, and bring machetes for the worst overgrown sections. The reward is having Tamarindo’s turquoise waters virtually to yourself, plus the strange satisfaction of driving where Marines once trained for combat.

Frequently asked questions
What's the minimum rig needed — can a stock Jeep Wrangler or Tacoma handle this?
High-clearance 4WD is the floor here, not a suggestion. Stock Wranglers and Tacomas with factory suspension can manage it, but expect low-hanging brush scraping your rocker panels and soft sandy sections that will punish anything without 4-low capability.
Is this trail accessible year-round or does the Caribbean wet season close it out?
November through May is the window — dry season keeps the trail passable and the water crossings manageable. June through October, hurricane season and heavy rains can turn the old Navy roads into impassable mud and swell those crossings into genuine hazards.
Do you need a permit to drive through the Culebra National Wildlife Refuge?
Yes — portions of this route pass through the Culebra National Wildlife Refuge, managed by the U.S. Fish & Wildlife Service, and access requires prior authorization. Contact the refuge directly at fws.gov/refuge/culebra before you go; showing up without clearance risks getting turned back or fined.
What's the hardest section actually like — where does this trail earn 'Difficult'?
The roughest stretch is mid-route where the old Navy bombing range roads have been reclaimed by vegetation and the surface breaks into loose rock and eroded ruts with no bailout. Tight overgrowth means you're committed once you're in, and a breakdown out there means a very long walk back to Dewey.
Can you get fuel and supplies on Culebra, or do you need to come fully loaded from the mainland?
Culebra is a small island — fuel availability in Dewey is limited and supply can be inconsistent, so top off on the Puerto Rico mainland before taking the ferry. Carry all the water, food, and recovery gear you need for the full day; there are no services once you leave Dewey.
