Well maintained motel by a lake.

Well maintained motel in attractive location opposite Boldt Castle in Lake Ontario. Nice big outdoor pool. Can walk to the restaurants of Alexandria Bay. Be aware that they sometimes have motorcycle groups staying there ( noisy engines). Easy access to Canada via nearby 24/7 border crossing.
