Since the opening of the Estoril Golf Course in 1936, a number of alterations and improvements have been made to its original layout. 

Overlooking Estoril and the sea, the 5262 meters long course is set amongst eucalyptus, pine and mimosa trees, giving it a uniquely colourful touch. The architect and the successive green keepers have made excellent use of these various trees which, together with the uneven terrain, make the Estoril Golf Course challenging in terms of accuracy rather than distance. The Estoril Golf Course demands excellent tactics. The visually stunning par 3 holes, although they vary in length, all pose particular challenges. 

Its hole number 16 is internationally well known, a Par 3 of 184 meters.
