Costa Rica concentrates on 51,000 km² what the rest of Central America has to offer. Five volcanic chains, two oceans, tropical forests that are home to 5% of the world's biodiversity. An organized Costa Rica tour allows you to see the essentials without sacrificing depth.
The Arenal, impressive in its permanent clouds. The Poás, whose turquoise crater is one of the largest in the world. The Rincón de la Vieja, with its bubbling mud quagmires. You don't "visit" a volcano in Costa Rica. You cross it.
Biodiversity. 900 species of birds, 35,000 species of insects, three-toed sloths in the trees of Manuel Antonio Park, sea turtles that lay their eggs at night on the beaches of Tortuguero. This density in such a small space comes from a conservation policy carried out for 40 years: 25% of the territory is protected.
The two oceans. The Pacific coast (Guanacaste, Manuel Antonio) is the most accessible. The Caribbean coast (Puerto Viejo, Tortuguero) is wilder, more humid, with its Afro-Caribbean heritage.
This is often the main reason to come. Some emblematic species and places to observe them:
Two- and three-toed sloth: all over the trees around Arenal, Manuel Antonio and Monteverde. Early in the morning, they sometimes come down within range of the lens.
Resplendent Quetzal: this is THE photographic trophy of Costa Rica. The most sought-after bird in Central America, with iridescent green feathers of 60 cm. It is found in the highland forests of Monteverde and the Los Quetzales massif between March and June.
Sea turtles: the beaches of Tortuguero (Caribbean coast) welcome green turtles from July to October. Night outings to observe the egg-laying are supervised by official guides. It is one of the most overwhelming experiences that a trip to nature can offer.
Macaw scarlet (parrot) and Swainson's toucan: Manuel Antonio is infested with them — in a good way. They eat the fruit directly from the trees in the park.
Venomous frogs: the dart frogs (red, blue, green) camouflage themselves under dead leaves. A naturalist guide spots them by sight. With the naked eye, you would pass by ten times.

10 days: San José (1 night) + Arenal/La Fortuna (3 nights) + Monteverde (2 nights, cloud forest and hanging bridges) + Manuel Antonio (3 nights, beach and monkeys). The classic tour that covers volcanoes, rainforest and Pacific coast.
14 days: Add Tortuguero (turtle watching, boat channels) and the Osa Peninsula (Corcovado, the densest forest in Central America).
7 days: Arenal + Manuel Antonio. The bare minimum to see something memorable.
Pacific Coast: dry season from December to April. Ideal for Manuel Antonio and Guanacaste. Little rain, animals more visible near watering holes.
Caribbean Coast: dry season from September to October and March to April.
The "green season" (May to November on the Pacific side) is cheaper and often beautiful: lush vegetation, fewer tourists. Rain in Costa Rica rarely lasts all day.
Sleeping in a lodge in the rainforest changes the perception we have of biodiversity. The best establishments are built on stilts to respect the forest floor. In the morning, the concert of howler monkeys and toucans replaces the alarm clock.
In Arenal, lodges with direct views of the volcano and access to the natural thermal springs (separate from the Blue Lagoon for a fee) are among the most exotic accommodations in Central America.
In Corcovado (Osa Peninsula), the ranger stations in the primary forest have no electricity at night. The most dense biological forest in the world is only a few meters away. It is an experience that is planned months in advance and requires a licensed guide.

Transfers. The road network off the main roads is difficult. The roads to Monteverde or Corcovado are long and strenuous. An organized tour manages private transfers and optimizes travel times.
Naturalist guides. The difference between a rainforest you walk through and a forest you understand. A certified naturalist guide spots a poisonous frog at 5 meters, identifies 200 species of birds by ear. It's an extra layer of reading that no app replaces.
Reserved access. Corcovado limits the number of visitors per day. Tortuguero supervises turtle outings with strict quotas. A local operator guarantees these accesses, where an independent visitor may find himself stranded.
