Perched on the south side of the Guerra Hills near the mouth of the famed Sierpe River, gateway to one of Earths most intense biological zones, this extensive 166.4-hectare (411.1-acre) tract includes a diversity of topographies and habitats perfect for an ecologically minded investor looking for a grand adventure. Off the beaten track and beyond the grid, this pristine environmental treasure includes sections of virgin rain forest, mature secondary forest, and rich mangrove wetlands, rising from sea level to an elevation of 200 meters (656.1 feet). Accessible most easily by boat, few places in the world are more ideal for ecological or scientific tourism, or the ultimate getaway estate. From the propertys heights you can watch migrating whales pass by the ever-changing vista of the Sierpe River flowing into the sea, or wonder at the grandeur of a full-blown night sky undisturbed by electric light haze. Wildlife, marine life, and birdlife abound, making for the most varied and exciting nature encounters. Both geographic and historical factors combine to make the Sierpe River and Drakes Bay area such an outstandingly diverse habitat zone. The Costa Rican Thermal Convection Dome, the only constant one of its kind in the world, combines cold-water and hot-water habitats for a rich mixture of marine life including more than four species of dolphin and six species of whales. For centuries this coastal region largely escaped human settlement that occurred primarily in the Central Valley, and even in recent decades its inaccessibility helped to preserve its pristine state. Much of the area is now permanently protected in some of Costa Ricas largest national parks, helping to insure the biological integrity of the zone and making opportunities such as this all the more unique and rare.
