Consider renting a car or hiring a driver for a more convenient and safe travel experience. The estimated cost of travel by car is $300-400, and it takes about 4-5 hours to travel between destinations. Alternatively, public transportation such as buses and taxis can be used, but it may take longer and be less comfortable.
If you have more time, consider adding a day trip to the Tortuguero National Park to see sea turtles or the Osaka National Park for a more rugged, off-the-beaten-path adventure. If you have less time, consider skipping Corcovado, as it is the most time-consuming destination on this itinerary. Also, be sure to pack comfortable shoes and clothing, as well as insect repellent and sunscreen for the jungle environments.
