Natural Highlights of Costa Rica: Self-Launched

Fly into Juan Santamaría International Airport (SJO). Take the red public bus (Tuasa/Station Wagon) from just outside arrivals into central San José for around £1.50 — or a pre-booked airport taxi for roughly £15. Check into your hostel in the Barrio Amón or El Poblado neighbourhoods. Spend the afternoon wandering the Mercado Central, grabbing a casado (traditional rice, beans and meat plate) at a local soda (diner) for under £5, and picking up any last supplies.

Rise early for the journey to Tortuguero — accessible only by boat or light aircraft. The most cost-effective route is a shared shuttle from San José to Cariari (book via Caribeños bus terminal or Interbus, ~£8), then a local bus to La Pavona pier (~£3), and finally a shared public boat across the lagoon to Tortuguero village (~£8). Alternatively, book a direct shared shuttle-and-boat combo through Interbus or Caribeños for around £25–35 all-in. Arrive by early afternoon. Check into a guesthouse in Tortuguero village — staying in the village (rather than the lodges across the water) is far cheaper and gives you an authentic local feel. Explore the village on foot, pop into the Sea Turtle Conservancy Museum (small donation requested), and pick up snacks at a local pulpería (corner shop).
