3 weeks in Costa Rica is the perfect amount of time to explore the country without rushing, while enjoying all the natural diversity—from the Pacific coast to the Caribbean, and everything in between.
Here’s the itinerary I personally followed, by bus (yes, it’s totally doable!), which allowed me to see some of the country’s most beautiful regions. 🌴🌋🐒
🛬 Day 1 – Arrival in San José
Just one night in San José to recover from the flight. Nothing major to see here, but it's a good starting point.
🌿 Days 2 to 6 – Corcovado & the Osa Peninsula
Straight down to Puerto Jiménez to explore the incredible Corcovado National Park, one of the most remote and wild areas in the country.
This is real jungle—toucans, monkeys, maybe even tapirs if you're lucky. It takes a bit of effort to get here, but it's absolutely worth it.
👉 Tip: I have the contact info of a great local guide for Corcovado. Feel free to reach out if you’d like their details!
🐋 Days 6 to 8 – Uvita & Marino Ballena National Park
Uvita is a chilled-out coastal town, perfect to slow down.
Don’t miss the iconic whale tail sandbar at low tide, and depending on the season, whale watching tours are a must.
🐒 Days 8 to 10 – Manuel Antonio
Yes, it’s touristy, let’s be honest.
But it’s also one of the best places to spot sloths, often up close!
The national park has amazing beaches, tons of monkeys, and easy trails—still a must-do despite the crowds.
🌲 Days 10 to 12 – Monteverde
Heading into the cloud forest now, for a change in vibe and temperature.
Monteverde is great for cooler air, lush scenery, and activities like ziplining, hanging bridges, and nature walks through the biological reserve.
🌋 Days 12 to 14 – La Fortuna & Arenal Volcano
One of Costa Rica’s top destinations, and for good reason.
The Arenal Volcano, natural hot springs, La Fortuna waterfall, and hiking trails around the volcano—it’s a perfect mix of nature and relaxation.
🔥 Days 14 to 15 – Liberia & Rincón de la Vieja
Quick stop in Liberia, mostly as a base to explore Rincón de la Vieja National Park.
I highly recommend doing both trails (Las Pailas + Catarata Escondida) — about 10 km total, doable in one day if you start early.
Expect bubbling hot springs, waterfalls, volcanic steam vents, and beautiful tropical forest. A real highlight!
🛶 Days 15 to 17 – Tortuguero
Now we head northeast to a completely different world.
Tortuguero is accessible only by boat, which already sets the tone.
It’s like a mini Amazon: boat safaris, wildlife everywhere, and if it’s the right season, you can watch sea turtles laying eggs on the beach—magical.
🌴 Days 17 to 20 – Puerto Viejo (Caribbean Coast)
Last main stop before heading back.
Puerto Viejo has a laid-back Caribbean vibe: reggae music, palm trees, bike rides along the coast, and stunning beaches like Punta Uva or Playa Cocles.
The nearby Cahuita National Park is perfect for spotting sloths and howler monkeys.
🛫 Days 20 to 21 – Return to San José
One final night in San José before flying home. Great time to relax or do some last-minute souvenir shopping.
📝 A Few Tips
It’s a packed itinerary, but a great way to see Costa Rica’s main highlights, especially for a first trip.
I did it all by bus, and yes, it’s totally doable!
👉 That said, renting a car gives you more freedom and flexibility.
But for budget-conscious travelers, buses are definitely the cheapest option, and they work—I did it!Bring light clothing + a rain jacket (it does rain often).
During high season (Dec–Apr), make sure to book accommodations and tours in advance.
