It comprises most of Parque Nacional Marino Las Baulas, the most important nesting site in Central America for the giant leatherback sea turtle. Here a 5km long stretch of white sand beach backed by a large mangrove estuary that is home to many nesting birds and other wildlife.
Due to laws protecting the nesting site, Playa Grande has remained virtually unchanged by the rapid coastal development that has proliferated along the coast in the area, known as the "Gold Coast" of Costa Rica.

When leaving the airport make the first left (if you go right you’ll be in Liberia within 10 minutes at the main intersection for the Pan-American Highway) follow this road past Filidelfia to Belen, make a right before you reach the gas station. This road will take you to 4km to an intersection, make a left.
Follow the road until you reach the town of Playa Grande.
You can reach Playa Grande by bus from Huacas, or take the bus to Tamarindo from Liberia (*colectivo* buses take as much as 3 hours) and use a water taxi to reach Playa Grande. Note that water taxis are not very convenient if you're carrying much luggage.
The Gray Line shuttle company also runs to and from Playa Grande hotels, albeit at a much higher cost than the public bus.
You can also get in by taxi boat from Tamarindo - go to the north end of the beach and just out of town, a few hundred metres before the Automercado, you'll see the boats - you can either make a short hop to the opposite sandbank, or a longer crossing up the river which drops off outside Hotel Bula Bula.
Bicycles are the best form of transportation to see the area. You can rent a car in Liberia or Tamarindo. Scooter rentals are available in Playa Grande.
Several hotels are located in the neighborhood of Palm Beach Estates, located 3 kilometers south of the town of Playa Grande. Palm Beach Estates offers a small supermarket and a couple of restaurants, but no other services. Be aware that you'll need to call or pre-arrange transport between the two areas if you do not want to walk, as you won't be able to hail a taxi on the street. You can walk between the two neighborhoods by road (unpaved and not recommended at night due to loose dogs) or by beach before 6 pm when it closes.
Surf the perfect waves that break along the shores of Playa Grande. If you don't know how to surf you can take surfing lessons at Una Ola Surf Resort.
