The Colonial Transisthmian Route

The Colonial Transisthmian Route of Panama was inscribed in 2025 under criteria two and four. It is a serial property: fortified settlements, historic towns, archaeological sites and surviving stretches of the roads that connected the Caribbean to the Pacific until the middle of the eighteenth century.

⚠ It is not the canal. The cited record describes the Camino de Cruces, one of the itineraries used to cross the isthmus, as the direct antecedent of the nineteenth century Panama Railroad and of the canal that opened in 1914. A paved mule road and a ship canal are different objects doing the same job three centuries apart, and the inscription is the road.

What the route was

Two paths carried the traffic. The Camino Real ran overland from Panama on the Pacific to Nombre de Dios and later Portobelo on the Caribbean, and carried the silver. The Camino de Cruces ran to Venta de Cruces on the Chagres river, where cargo transferred to boats for the rest of the journey, and carried the heavier and bulkier freight. Both were paved in stone where the ground demanded it, and both are older than the Spanish: the crossing was in use long before anyone arrived to pave it.

What to see

• Panama Viejo. The original city, founded 1519, sacked by Henry Morgan in 1671 and abandoned. The roofless cathedral tower and the convent walls stand on flat grass with the modern skyline directly behind them, which is the single most quietly eloquent view in the country.
• Casco Antiguo. The city the survivors built on a defensible point after 1671, now the restored old quarter and the best place in Panama to spend an evening.
• The Camino de Cruces. Stretches of the original stone paving survive inside Camino de Cruces National Park, a short drive from the city, and can be walked. It is muddy, slippery, genuinely atmospheric and much harder going than the distance suggests.
• Portobelo and San Lorenzo. The defensive system at the Caribbean end, inscribed separately in 1980. See the Portobelo guide.

Walking it

• Go with a guide. The trail is not always obvious, the forest is thick and the stones are slick.
• Boots with grip, long trousers, repellent and far more water than the distance suggests.
• Early morning is cooler and the wildlife is awake. It is also when the light reaches the cut, which is when the paving looks like what it is.

Panama's five inscribed properties include this route, the Caribbean fortifications, Darien National Park and two further natural properties. For what to bring, see the packing list; for getting to the trailheads, see getting around.
