I went in August 2005 to have an introductory flight to this soaring club. It's located in Santo Tomé del Puerto, a small village in the province of Segovia, about 65 miles to the north of Madrid. It's a great area to fly at, due to its great weather conditions. I had a great time flying like a passenger in one of their Blaniks, the EC-CXT.
