Costa Rica's southwest region runs up the Pacific coast and is characterised in particular by the stunning Oso Peninsula, home to a unique fusion of wildlife and vegetation. As well as dazzlingly rich forestry, you can enjoy the fantastic coastline of the Puntarenas province. Whilst nearby beaches like Jacó are modern and urbanized, those within the national parks remain untouched by human hands and offer a splendid haven to be at one with the most beautiful elements of our natural world.
