There are ,2 waterparks on the Island: Hydropolis on the outskirts of Acharavi on the north coast, ,and the larger Aqualand in Ag Ioannis, just outside Corfu Town. ,Both parks have a good selection of slides, pools and various refreshments available. Aqualand is by far the largest of the waterparks and in fact one of the largest waterparks in Europe with a big selection of rides and activities for all ages (including a very sedate 'lazy river' for older party members!) It has a couple of cafes and snack bars, a small shopping area and plenty of sun loungers and is open from 9am-8pm daily all Summer.
One of the hotels in Sidari also has a few small waterslides and a pool, open to the public.
