The southwest corner of Costa Rica’s Nicoya Peninsula rewards curiosity—but only if you’re willing to accept a bit of friction. Traveling from San Francisco de Coyote toward Santa Teresa or Montezuma, you’ll quickly notice that any navigation app insists on a long detour via Lepanto, even though the destinations appear quite close as the crow flies. The reason is simple: the direct coastal route involves three river crossings.
There was never a bridge here. This stretch of coastline has always been traversed by fording rivers, and that reality shapes both the pace and the experience of travel. If you’re prepared, it’s neither reckless nor extreme—it’s simply how this part of Nicoya works. Locals cross these rivers regularly, and tow trucks are familiar with the occasional tourist mishap. The key is preparation, timing, and listening carefully to local advice, especially to avoid the unpleasant scenario of getting stuck midstream—particularly in rivers known to host crocodiles.
The Three Rivers You’ll Cross
Driving south from Coyote, the route requires crossing, from north to south, Río Bongo, Río Caño Seco, and Río Arío. I wasn’t exactly thrilled at the idea of fording rivers, especially with the possibility of being stranded for hours waiting for help. But between the growing sense of excitement and repeated reassurance from locals, we went for it.
Río Bongo was by far the most significant and intimidating of the three—and the one most travelers remember. Wide, often murky, and very much alive, it is known to host crocodiles. This isn’t folklore. Warning signs—sometimes half-destroyed by weather—are nailed to trees near the crossing points. I didn’t see any crocodiles myself, but the knowledge that they are there is very real. That said, the river is crossed daily by locals, motorcycles, cars, and even cyclists, all following very specific rules.
Río Cano Seco, encountered shortly after, can look deceptively similar in size and conditions and may also host crocodiles. Río Arío, the final crossing before reaching the Santa Teresa–Montezuma area, is narrower but can still be challenging depending on recent rainfall.
Vehicles: Height Over Horsepower
You don’t strictly need a 4×4—but you do need a high-clearance vehicle. Ground clearance matters far more than traction. Low cars are simply not suitable. A compact SUV or pickup is ideal.
Equally important is how you cross. You never drive straight across a river. The correct technique is to follow a gentle crescent-shaped trajectory downstream, where water flow naturally deposits firmer gravel and stones. This improves traction and reduces resistance from the current. Enter slowly, keep a steady pace, never stop midstream, and avoid sudden acceleration. This isn’t about force—it’s about reading water.
Timing, Tides, and Conditions
Seasonality is crucial. These crossings are generally manageable during the dry season and early shoulder months, typically January through April, when water levels are lower and currents calmer. After heavy rain or tropical storms, conditions can change overnight.
Tides also matter. Even rivers are influenced by tidal cycles near the coast, and locals will tell you exactly when low tide makes crossings easier. Always check recent rainfall, ask around, and never attempt crossings at night. Fuel up in Coyote, carry water, and allow extra time. If conditions feel wrong, turn back—there’s no shame in respecting rivers that have shaped this landscape for centuries.
Crocodiles: Context, Not Panic
Yes, crocodiles are present, especially in Río Bongo and Río Arío. But context matters. They tend to stay in deeper, calmer sections and generally avoid shallow, disturbed crossing points. The rule repeated locally, without drama, is simple: do not swim. Walking or driving across is considered far safer than entering the water freely.
This isn’t recklessness—it’s lived experience. Locals cross these rivers routinely, always with attention and respect. The same will be asked of you.
Erikson and the Value of Local Knowledge
Near Río Bongo, travelers often notice a small concrete house with a sign reading “Expert Crossing Rivers – Free Information.” This is where Erikson, a local who knows the river intimately, offers guidance. He doesn’t run tours, doesn’t ask for payment, and doesn’t exaggerate the risks. He simply explains where to enter, where to exit, and which line to follow based on that day’s conditions.
Coming from the north, Erikson can visually guide drivers, confirm whether the crossing is advisable, and turn uncertainty into informed decision-making. This route isn’t abandoned—it’s supported by people who understand the land far better than any navigation app.
The Alternative Route: Río Frío
If conditions feel uncertain, the Río Frío route is the safer and more predictable option. Running inland from Cóbano, it involves five river crossings, but they are generally shallower and less volatile. This route is usually passable from November through August, even outside peak dry season. Most importantly, RíoBongo is crossed here via a concrete bridge, eliminating the most critical risk point. The drive is longer—about 36 km from Cóbano to San Francisco de Coyote—but far less stressful.
One absolute rule: never drive on the beach. It’s illegal, dangerous for people and wildlife, and can leave you stranded by tides with serious consequences.
An Unexpected Adventure
We quickly learned that river crossings in southwestern Nicoya aren’t a stunt or a thrill-seeking shortcut. They are simply how this territory works. But avoiding Lepanto did save us several hours, and it turned out to be incredibly fun and exciting. Moreover, when we finally reached Montezuma, the arrival felt earned rather than given for granted.
