Sea swimming has gone from a Wednesday-evening eccentricity to a mainstream pursuit in Ireland over the past few years. Here is how we would think about doing it from the Derrynane, in any month of the calendar.
Where to swim
Carroll’s Cove — two minutes from the hotel — is your most sheltered option. The cove gets calm at low tide, the entry is over sand and a few rocks, and there is a flat ledge at the back to leave your dry-robe and a flask.
Derrynane Beach — five minutes by car — is wider, has lifeguard cover in summer, and is the choice for a longer swim.
For the brave: a steep path down to a tiny rock pool just south of the hotel where serious sea-swimmers gather most mornings.
When
- Summer (June–September): water 14–18°C. Comfortable for most. Swim caps optional.
- Autumn (October–December): 11–13°C. Wetsuit or experience helpful.
- Winter (January–March): 8–10°C. Quick dip only without a wetsuit. Bring company.
- Spring (April–May): 9–11°C. Worst of both worlds — wetsuit recommended unless you are acclimated.
Equipment
A neoprene cap and gloves transform cold-water swimming. A dry-robe (or a thick towelling poncho) for after. A hot flask in the car. Sandals you can put on with wet feet. Reception keeps a small lost-and-found of dry-robes for guests; ask if you forgot yours.
A short word on safety
Swim with someone if you can. Tell reception your rough plan if you cannot. Know the tide and know your exit. The coast is wonderful but it is properly Atlantic — never your average swimming pool.
