Hi there, we’ve (family of three) just booked flights to Athens for the first week of April. Our plan is to get the boat over to Hydra and spend a week there in an Airbnb and come back to Athens and fly home. I’ve been to Hydra twice as an adult but 15 years ago and loved it. My query is will it be remotely suitable for a four year old? Aware it’s too cold for sea swimming in April but is there enough pottering about to do there? Will we get bored or is there exploring to do? I love the idea of no cars. Any thoughts would be great. Thanks.
