The Hills Course is Costa Navarino's fourth golf course. It was designed by Jose Maria Olazabal and opened in 2021. The course is in a more secluded setting than the other three courses, offering dramatic views of the surrounding hills and valleys of the beautiful Messenia mountains.

Narrower fairways and smaller greens often surrounded by bunkers makes the Hills course a fantastic test for the better golfer. Players of all abilities however will love the Hills Course, as multiple tee-boxes ensure a fun and fair challenge for every level of golfer.

One of the most memorable holes on the Hills Course is the par-3 15th hole. The tee shot is played over a deep gorge to a green that is enveloped by five big bunkers. The hole requires accuracy and distance control, as anything short could disappear into the gorge and long will take you into the trees.
