Puerto Caldera, Costa Rica • December 27, 2015
About This Experience
This full-day shore excursion from Costa Rica’s central Pacific coast combined two heritage-rich experiences: a vintage train ride along the historic Pacific Railroad and a guided pontoon boat cruise through the Tárcoles River’s biodiverse mangrove system. Most activities were seated, with minimal walking required between transport points.
🌄 From Coast to Countryside
Upon arrival in Puerto Caldera, located on the Pacific coast of Puntarenas Province, our group of approximately 35 passengers boarded an air-conditioned motorcoach for the first leg of the excursion. The weather conditions were typical for the region—hot with a steady coastal breeze. As one of Costa Rica’s primary commercial and cruise ports, Puerto Caldera functions as a critical hub for both freight operations and tourism. Shortly after departure, the urban and industrial landscape began to transition. Within minutes, the route shifted to reveal a more rural backdrop of agricultural fields, lowland forests, and scattered settlements. The drive continued inland toward the Pacific Railroad boarding site, where a restored heritage train awaited.
🚇 Stop 1: Scenic ride aboard the Pacific Railroad
📍 Location: Estación Sánchez, Puntarenas Province, Costa Rica
⏳ Time Spent: Approximately 1 hour
After a brief motorcoach transfer from the coastal highway, we arrived at Estación Sánchez, a small platform serving as the boarding site for the heritage segment of the Pacific Railroad. The train, composed of two restored passenger carriages and a red caboose, was positioned directly alongside the waiting motorcoaches, allowing passengers to board without stepping onto uneven gravel or trackside terrain. The process was highly organized, with minimal delays during boarding.

Once on board, passengers settled into bench seating inside the vintage railcars, all of which featured large sliding windows for open-air views. The train departed Sánchez and followed a rural corridor toward Ceiba, passing a varied landscape that included cultivated farmland, scattered ranch houses, and segments of lowland forest. Several hand-cut tunnels along the route required caution; staff reminded passengers to keep limbs inside the windows as clearances were minimal.

Midway through the ride, an unscheduled stop occurred when a GoPro camera—extended too far outside the window—was caught by overhanging brush. The crew quickly brought the train to a stop, reversed, and successfully recovered the equipment. The incident was handled efficiently and with good communication.
As the train continued, riders observed the Mantled howler monkey, one of the region’s most iconic species. A lone individual was spotted reclining in the upper branches of a roadside tree, quietly observing the train’s passage—an unexpected but welcome sight along the otherwise mechanical route.

🚉 Railway Heritage: The Pacific Railroad was built using imported British steel and U.S. locomotives, with construction hampered by landslides and flooding due to Costa Rica’s rugged terrain.
🏞️ Stop 2: River safari through the mangroves
📍 Location: Tárcoles River Dock, Tárcoles, Puntarenas Province, Costa Rica
⏳ Time Spent: Approximately 1 hour
After completing the rail segment of the tour, we reboarded our motorcoach and continued northwest toward the Tárcoles River, one of Costa Rica’s most ecologically important waterways. Known for its mangrove-lined channels and exceptional wildlife density, the river serves as a natural corridor between coastal lowlands and inland ecosystems. The final leg of the drive took us over a series of unpaved rural roads, where the surface conditions grew noticeably rough, testing the suspension of the bus but offering an early glimpse of the natural landscape to come.
Upon arrival at the river landing site, guests were greeted with a refreshment station featuring chilled fruit juices and freshly sliced pineapple, served under a shaded shelter near the dock. The pause allowed for hydration and a brief orientation before boarding the flat-bottomed pontoon boat that would carry us through the wetlands.

The vessel’s wide, open design allowed for unobstructed views as it entered the mangrove estuary, where the river’s brackish waters meandered through thick stands of red, black, and white mangrove trees. Almost immediately, wildlife sightings began. American crocodiles, some partially submerged and others basking on muddy banks, were visible along several bends of the river.

Termite nests the size of basketballs clung to tree trunks above the waterline, while a variety of bird species—including great egrets, little blue herons, and green kingfishers—moved between the branches or skimmed the surface of the river.

The mangrove environment, dense and visually layered, occasionally opened to reveal secluded pockets of activity, offering passengers fleeting views of otherwise hidden wildlife. The calm navigation and abundance of sightings made this portion of the excursion both informative and ecologically significant.

🦜 Wildlife Insight: Over 300 bird species have been recorded in the Tárcoles River basin, making it a top destination for ornithologists and birding tours in Central America
🚍 Return through Costa Rica’s Pacific interior
As the excursion concluded, we boarded the motorcoach once again for the return drive to the Puerto Caldera pier. The route retraced our earlier passage through the agricultural and forested landscapes of Puntarenas Province, now cast in the subdued light of late afternoon. The sun, descending toward the Pacific horizon, projected long shadows across open fields and low-lying foothills.
💙 Our Favorite Moment
The most memorable moment occurred during the pontoon boat cruise, when a large crocodile resting on the riverbank suddenly opened its mouth wide just as we looked over. The timing was startling and exact, offering a dramatic reminder of the raw power and presence natural wildlife.
🐊 Behavioral Fact: American crocodiles open their mouths wide while basking as a form of thermoregulation, releasing heat without expending energy.
