Promote the development of nature tourism in the Algarve, this is the mission of the Nature Tourism Biennial (BTN). And biological pools as a sustainable and ecologically proven footprint, available on the national market since 1995, fit perfectly into the motto.
We invite you all to visit our stand of Biological Pools in the 2019 edition of BTN at the Fair of Aljezur. The Biennial has a program for all those interested in nature tourism, whether near or far. It is open, Friday through Sunday, from 22 to 24 February, from 9.30 to 10 p.m. Entrance is free.
