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.

The staff and location were wonderful. We were scared when we walked into the Manor Restaurant because literally no one was there on a Saturday night - we had a wonderful dinner overlooking Boldt Castle. The prime rib was excellent! The hotel and property have not had an update since probably the 1970’s but it was clean.
