The Talamanca at full volume: early starts on the ridge, rain by mid-afternoon, and the Osa in whale season.
The rainy season on the Pacific slope keeps office hours: clear or dry mornings, cloud building towards midday, rain in the afternoon and early evening. So the expedition starts early. On the Nueve Cumbres we leave San José as early as the drive allows and aim to be off the ridge before the afternoon closes in; the Queen Stage descent into the Savegre runs through a cloud forest that has been wet for three months — moss swollen, every stream loud, the oaks in mist.
This far south there is no veranillo, the mid-year dry spell Guanacaste gets; August on the southern Pacific is simply the wet season, and the Osa is at its most alive. Around Drake Bay much of the rain falls at night; the days bring showers and rainbows, and from July to mid-November the bay is the breeding ground of the southern humpbacks — whales that feed off the Antarctic Peninsula and southern Chile — so a sighting with calves is a real possibility.
Who it is for: runners who do not mind weather, water on the trail and a country quieter than in the dry season. Expect mud, full rivers and the light that only comes after rain. Kit is a rain shell you trust and shoes that drain.
A real itinerary, with real distances, real lodges, and the meals that bookend each day — dated for the rainy season.
Each route is drawn from our own field reconnaissance. Select a day to read its profile, or follow the line of the journey end to end.
San José Arrive in Costa Rica's vibrant capital, where you are welcomed and transferred to your comfortable base near the airport. The afternoon is yours to rest and acclimatise.
At 17:00, meet your expedition leader and fellow runners in the hotel lobby for the welcome briefing, followed by a relaxed welcome dinner.
Cordillera de Talamanca Rainy seasonEarly start; the aim is to be off the ridge before the afternoon cloud.
After breakfast the support van climbs the Pan-American Highway into the Macizo del Cerro de la Muerte — a high section of the Cordillera de Talamanca and the continental divide of southern Costa Rica. The day's route is the local Nueve Cumbres traverse — 17.3 km along the ridgeline, summiting Jaboncillo, Estaquero, Sákira, Sábila, Zacatales, Asunción, Páramo and Cerro Buenavista (3,491 m, the highest point of this massif and the peak the highway is named for), with a final out-and-back to Cerro Frío. Nine in all — roughly 1,640 m of ascent, 1,190 m of descent. The trail starts at the treeline and crosses it several times along the ridge; every summit is in páramo, the tropical alpine grassland that in Costa Rica only exists above 3,000 m.After breakfast the support van climbs the Pan-American Highway into the Macizo del Cerro de la Muerte — a high section of the Cordillera de Talamanca and the continental divide of southern Costa Rica. The day's route is the local Nueve Cumbres traverse — 10.7 mi along the ridgeline, summiting Jaboncillo, Estaquero, Sákira, Sábila, Zacatales, Asunción, Páramo and Cerro Buenavista (11,453 ft, the highest point of this massif and the peak the highway is named for), with a final out-and-back to Cerro Frío.

From Buenavista the van picks you up and drops 1,500 m into the Río Savegre Valley — a different country at a different altitude. Tonight: Lauráceas Lodge. Ten chalets in the cloud forest, a family kitchen with trout and apples from the valley, and, with luck, the resplendent quetzal feeding outside your window in the morning.From Buenavista the van picks you up and drops 4,900 ft into the Río Savegre Valley — a different country at a different altitude.

Cloud forest Wake to birdsong and the cool mist of the Dota Valley. Today's run is a 9.2 km loop from Lauráceas — climbing 500 m through montane oak forest on the eastern boundary of Los Quetzales National Park to roughly 2,625 m, then descending back to the lodge. The trail runs under moss-draped robles (Quercus) and aguacatillos — wild avocados in the Lauraceae family, which is what the resplendent quetzal feeds on, and why San Gerardo holds the largest year-round quetzal population in Costa Rica. The lodge takes its name from the same family of trees.Wake to birdsong and the cool mist of the Dota Valley.

The afternoon is yours. Rest at the lodge, walk down to the San Gerardo waterfall on the Río Savegre, take a birdwatching outing with a local naturalist — emerald toucanet, fiery-throated hummingbird, sometimes the quetzal at close range — or visit a family-run coffee finca in the valley.
Queen Stage Rainy seasonThe descent runs wet and the Savegre full; on the self-supported stage you carry your own layers.
The signature day. Twenty-five kilometres point-to-point from Armonía Ambiental in Providencia (~1,800 m). A steep climb out of the village opens the day; the first seven kilometres undulate along the high ridge to a top of 1,910 m, and then a long descent drops more than a thousand metres into the cloud forest. La Chaqueta is the first clearing in the mountain — you reach it as the trees give way. The trail follows the Río Savegre down through the valley below, then closes with a final 4 km, 455 m climb into the Zona Protectora Cerro Nara. The finish line is Ranchos Tinamú (~814 m), a community-run rural-tourism lodge in San Isidro de Dota named after the great tinamou whose call carries through this forest. Total: roughly 1,380 m of ascent, 2,350 m of descent — self-supported in the sense that no van follows you.The signature day. 16 miles point-to-point from Armonía Ambiental in Providencia (~5,900 ft).

What the day actually is: at three or four houses down the route, mountain families open their kitchens to runners — coffee, agua dulce, fruit, an empanada, a chair in the shade. The full story is in the Field Notes ('The Queen Stage, told slowly'). After Ranchos Tinamú the support team continues you out to Hotel Parador on the Manuel Antonio coast — five hectares of rainforest above the Pacific, where the next two nights are. Tonight dinner is yours: recover quietly at the hotel, or tell us the kind of table you want in town and we'll have it booked.What the day actually is: at three or four houses down the route, mountain families open their kitchens to runners — coffee, agua dulce, fruit, an empanada, a chair in the shade.

Pacific coast Rainy seasonAfternoon storms; the sea turns murky near the river mouths.
Trade mountains for coastline on the Reto MAE — Manuel Antonio Extreme — the local 9.5 km coastal trail and the route of an annual November race. From Quepos south to the gates of Manuel Antonio National Park, the path snakes through rainforest, climbs onto cliff-top bluffs, and drops onto seven Pacific beaches in sequence: Rocosa, Tulemar, La Vaca, La Macha, Biesanz, and the rest. Don't let the sea-level start fool you — the day accumulates around 425 m of gain over short, sharp pitches to each viewpoint.Trade mountains for coastline on the Reto MAE — Manuel Antonio Extreme — the local 5.9 mi coastal trail and the route of an annual November race.

After the run, spend a relaxed afternoon at Hotel Parador — five hectares of rainforest, cliff-top pools above the Pacific. Optional: a guided visit to Manuel Antonio National Park (three monkey species including the endemic Central American squirrel monkey, three-toed sloths, agoutis), or sunset kayaking along the coast.

Drake Bay Rainy seasonMuch of the rain falls at night; humpbacks with calves are possible in the bay.
After breakfast, journey south to the Sierpe River and board a boat that winds out through the Sierpe-Térraba mangroves — the largest mangrove system in Central America — into the open Pacific, and around the headland into Bahía Drake. From the village of Agujitas, the day unfolds along the Pacific coastal trail: 16.6 km of singletrack through the Punta Río Claro National Wildlife Refuge, tracing hidden coves, headlands, and stream crossings as the path slips deeper into the Osa Peninsula. Scarlet macaws in the beach almonds — the Osa holds the country's largest population.After breakfast, journey south to the Sierpe River and board a boat that winds out through the Sierpe-Térraba mangroves — the largest mangrove system in Central America — into the open Pacific, and around the headland into Bahía Drake.
