They will train at the Los Angeles de San Rafael ground which is 1240 metres above the sea level.
The training module has been designed to get the footballers in right physical shape for the demanding second season of ISL starting October 3.
The ATK contingent will be leaving for Spain on Tuesday morning to train under Head Coach Antonio Lopez Habas and Trainer Miguel Martinez.
Due to National team commitments for the Pre-World Cup qualifiers defender Arnab Mondal and right back Rino Anto will be joining the team later in Spain.
"The team is confident and ready to take on the new season of ISL. The training will be basic yet strict. The technical aspect of the players would be scrutinized for the whole month in order to achieve their optimum potential," coach Habas was quoted saying in a media release.
