Watersports — City beach, ~10 min drive or 30 min walk from the lighthouse
Aqua Sport Center runs nine watersports directly off Alexandroupolis's own city beach, split between high-adrenaline options — crazy sofa, rings, water sled, water skiing, kneeboarding, and jet skiing, mostly in 15–20 minute sessions — and calmer ones: sea bike, SUP, and canoe/kayak, rented by the hour.
It's a different location from the watersports operators further out at Agia Paraskevi — this one sits on the city beach itself, open daily from 10:30am to 9pm, June through September, weather permitting, with certified instructors running every session.
