We would highly recommend staying at Serenity 22 Barend. The lodge was very comfortable and had been cleaned to a high standard. There are wonderful views of the loch from the balcony. The site/village is quiet and well tended. The swimming pool is small but as you book the whole pool for your party this was not a problem. We also enjoyed a meal in the pub onsite.
Within walking distance are the deer park, loch and beach. We had a lovely time eating breakfast whilst watching the deer.
Other than this you would need a car to explore the beautiful Scottish countryside and coast. Within a 45 minute drive there are many towns, beaches and lochs to visit. We particularly enjoyed rock climbing on Powillimount beach, rock-pooling on Mossyard beach and lunch at the Designs cafe in Castle Douglas.
