We had a fantastic stay in Goleen Harbour. We, a family of 4 with 2 big kids aged 12 and 14, stayed in the Fastnet cabin for a weekend in September. The cabin was just right for our needs, we had a self catered dinner in on the first night. The cabin had everything we needed to cook a meal, including oil and salt/pepper. The beds were really comfortable, and we all slept well, even with the torrential rain on the second night. The ensuite bathroom was just luxury, hot water on demand. The cabin feels surprisingly spacious, and is very well laid out as a flexible space for dining, sleeping and relaxing. The little deck was lovely to sit on while having a beer and watching the harvest moon rise, on a perfectly still night.
The grounds are beautiful and wild, and Matt has made a lovely path that circles the harbour, although I didn't manage to get a swim in the swimming spot, so I'll have to come back. The backdrop of Goleen harbour is stunning, not to mention the view of the fastnet.
The village is a five minute walk and delicious fish and chips at Colin's place while having a pint from the adjoining pub made a perfect second night's dinner. If you want dinner in Heron's Cove, make sure to book a few days in advance, which we failed to do.
We had one full fine day to take in Mizen Head, a swim in Barley Cove and Three Castle Head, all of which are within a 20 minute drive, or an easy enough cycle 45 mins from Goleen to Three Castle head, passing Barley Cove on the way. Crookhaven is also close by and a lovely spot for lunch.
We would highly recommend Goleen Harbour for a weekend trip.
