I have Vacationed in Biddeford Pool for 20 years and my daughter has enjoyed every visit. It is easy to get to from her home in New York and my home in Washington DC Being on the water is great for Kayaking and there is great access to the two mile sandy beach. There are nearby gold and tennis facilities
You can walk down the lawn and launch kayaks into the pool or take a walk through the Marsh and grab a coffee at Goldthwaite's. Order your cooked lobsters from the Store/lobster pound or barbecue off the back deck/patio.
