The shorter cruise · from Side

Quick answer
The shorter option of the Green Canyon catamaran tour from Side: 2.5 hours on the emerald reservoir, with the same hotel pickup, guide, swimming breaks, fishing opportunity, soft drinks on board and open buffet lunch as the 4.5-hour option, and the same return at around 15:00. It costs €33 per adult and €20 per child aged 3–11, runs daily in season, and is paid on the day.
The short option of the Green Canyon catamaran tour: 2.5 hours cruising the emerald reservoir above the Oymapınar dam, between steep pine-covered canyon walls, with swimming breaks, a fishing opportunity and an open buffet lunch. The day itself is the same as the 4.5-hour option — same hotel pickup, same lunch, same return at around 15:00 — with less time on the water.

For the greenest water, shoot with the sun high and behind you, and point down at an angle rather than across the glare. The narrow sections give the best wall-and-water frames, so be on deck when the catamaran enters them. Keep your phone in a dry bag during the swimming breaks, and remember the professional photo service is optional.
The Green Canyon reservoir is fresh, spring-fed mountain water held behind the Oymapınar dam, while Side beach is a warm, shallow sea. Spring water filtered through limestone is both the reason the lake is emerald and the reason it feels cooler — refreshing rather than cold, and the part of the catamaran cruise most guests talk about afterwards.
