About Us

Our Story
Nireas opened in June 2015 and stays open all year, with activities varying with the seasons. Summertime our main focus is on the sea, with scuba diving and snorkeling as our core activities. All through the year we of course also offer our clients half – full day trekking tours. Wintertime we extend our selection of trekking trails and offer winter visitors weekly trekking programs. We put larger focus on rappel trainings and organize weekend canyoning excursions to the east side of Crete.
Our mission is to keep both locals and visitors active by offering a variety of fun and memorable outdoor activities for all
levels of fitness. As passionate nature enthusiasts we are hoping our work will help to increase interest and awareness of
nature, and to aid to its preservation.

We are driven by values
Small groups, with safe and personal service, in a fun and friendly environment is key for us. All of our tours offer free hotel transfers and include all sports equipment. All of our trekking tours include our private rescuing service.
