Flight
Costa Rica has two major airports. If you're coming just for the long weekend, we recommended flying into Liberia (LIB) airport. We're arranging shuttles from the airport to Nosara on both Wednesday 2/7 and Thursday 2/8, or you can rent a car and drive yourself (details below). If you plan on coming in Thursday 2/8 (and want to go to the welcome party), we recommend that you get a flight into LIB by 3:00pm at the latest, so you have time to get your luggage, get on a shuttle, and get to your AirBnb and relax before the party. If you plan on coming in Wednesday 2/7, we'll have multiple shuttles depending on when people come in, so feel free to do what works best for you. We will also be arranging shuttles from Nosara to LIB airport on Sunday 2/11 throughout the morning/day. We recommend getting a flight out of Liberia no earlier than 1:00pm (CR time). This will mean an 8am shuttle departure from Nosara!
Flight
If you're planning on taking an extended vacation in Costa Rica (which we totally recommend!), you could fly into San Jose International Airport and do a road trip through the rainforests, volcanos, and coastal towns of Costa Rica and end up in Nosara. It's a four to five hour drive from San Jose to Nosara, so we don't recommend flying into San Jose if you're planning a shorter trip.
Rental Car
If you would prefer to rent a car and drive to Nosara, Vamos Rent-a-Car is a reputable car rental company in Costa Rica that we've used multiple times, but you can search rental cars for Liberia / San Jose in Kayak, Google, etc. and find all the major brands (Hertz, Avis, etc.) if you prefer to use something you're familar with.
