Head out of Kardamena for the day and get drenched at the Lido Waterpark – one of Greece’s biggest and the only one on Kos. You’ll be picked up at your hotel by one of the 2wentys team at 10.30am, and they’ll get you there in under half-an-hour. This place is absolutely massive – we’re talking 75000 square metres. And the stuff here is as high-energy as Kardamena’s clubs. You can hit six different types of wave in the 1500-metre wave pool, go flying down the near-vertical Kamikaze slide, and plunge through the Black Hole. Plus, the ten-person whirlpool is good for a giggle. You’re not getting picked up until 4.30pm, so you’ve got plenty of time to try everything. Just remember to bring a bit of cash for your locker and a bite to eat.
