The Blue Lagoon, in the Serra de Sintra is the perfect meeting point of man with nature. This is the ideal place for good moments spent in family, but is also often the starting point for mountain bikers. Their circuits with paths that meander through the interior of the mountain, are the most resistant to embark on great adventures for ascents and challenging descents. In the Blue Lagoon, you can enjoy just the pure and refreshing air and contemplate nature in its full.
