With 21 days ahead of you, you no longer have to choose. It's the ideal length to link the north, the Pacific, and the country's deep south, where most tours stop short. Here's the3-week Costa Rica itinerary I build for travelers who want to experience the whole country.
The 3-week itinerary at a glance

Nineteen nights, real ecosystem diversity, and always reasonable drives. It's the grand tour, without the fatigue.
The details, stage by stage
The start follows the classic route — Tortuguero, Arenal, Monteverde, Manuel Antonio — detailed in our 15-day itinerary. The magic of 3 weeks begins after that.
The Osa peninsula and Corcovado
Heading for the deep south: you reach Drake Bay by boat, the gateway to Corcovado, one of the densest biodiversity sanctuaries on the planet. Macaws, tapirs, spider monkeys: the jungle in its rawest version.
The southern Pacific and the whales
Back up to Uvita and Marino Ballena park, one of the world's best spots for humpback whales (July-October, December-March), before a few quieter days by the water.
San Gerardo de Dota, highland Costa Rica
On the way back, a stop in the cold valley of San Gerardo de Dota : bamboo forest, waterfalls, and the mythical quetzal. A little-known Costa Rica, green and silent.
Possible variants
- Southern Caribbean: add Puerto Viejo and Cahuita for the Afro-Caribbean culture.
- Two-country combo: three weeks also lets you link Costa Rica with a neighbor — see our comparison Costa Rica or Panama.
- Family pace: lighten the load, more beach, less driving.
Practical advice
Over 3 weeks, a mix of car + transfers (boat for Tortuguero and Drake) is ideal. Plan your budget — the longer the stay, the more optimization matters — and choose the right season with our guide When to go to Costa Rica. To book everything, build your trip on Toucan Dynamics.
Frequently Asked Questions
Is 3 weeks too long for Costa Rica?
No, it's the ideal length to add the deep south (Osa, Corcovado) and the southern coast without rushing.
Can you combine with another country?
Yes: Nicaragua or Panama link up very well with Costa Rica over three weeks.
Do you have to drive the whole time?
No: some stages (Tortuguero, Drake) are done by boat, which is restful and part of the adventure.
