Pembrokeshire & West Wales Group Accommodation: The Planning Guide

Pembrokeshire has the coastline people cross the country for and roughly none of the traffic. It has been a National Park since 1952 — the only one in Britain that is predominantly coast — and its 186-mile coast path, opened in 1970, is the most celebrated stretch of the 870-mile Wales Coast Path that has followed the whole Welsh shoreline since 2012. For a large group it offers what Cornwall and Devon offer, with fewer people on the sand and a very different feel to the drive. This guide covers getting a big party there, the houses and where they sit, the seasons, and how the rest of West Wales fits around it.

The only coastal national park

Most national parks are about height; this one is about edge. The park runs almost the entire Pembrokeshire coast from the Teifi estuary in the north to Amroth in the south, with beaches that change character every few miles — the wide sands of Broad Haven and Whitesands, the sheltered curve of Barafundle, the small harbour at Porthgain with its converted-boathouse pub. Tenby, the walled medieval town, is the practical hub in the south with its harbour pubs; St Davids, the smallest city in Britain, anchors the north. Because the coast path threads the whole way, a group walk of any length can start and finish wherever the house is, which matters more than it sounds when twenty people have different ideas about how far “a walk” is.

Getting a large group to West Wales

Be honest about the drive. The M4 ends at Pont Abraham beyond Swansea and the A48 and A40 carry you on through Carmarthen to Haverfordwest; from London allow four to five hours, from Birmingham around three and a half, from Manchester about four. That is longer than Devon for most of England and it is the trade you make for the emptier coast. Trains run to Haverfordwest, Pembroke and Tenby via Swansea — roughly three and a half to four hours from London Paddington — which is realistic for a handful of guests without cars, but a whole party with luggage and the weekend’s food wants vehicles. Plan the shop for Haverfordwest or Carmarthen on the way in rather than hoping the village has what twenty people need for three days; our meals and catering guide covers the big-shop logistics for exactly this kind of trip.

The houses, and where they sit

“Pembrokeshire” on a listing can mean the clifftop or a farm twenty minutes inland, and both are good for different groups. Trebrowen at Angle, near the mouth of Milford Haven, sleeps 24 across ten bedrooms with a heated outdoor pool, a hot tub and a games room — the combination you want on a coast where the weather turns in an hour — and it welcomes dogs. Penty Parc is a Grade II listed house near Haverfordwest in rural Pembrokeshire, sleeping 17, with gardens and countryside views and the beaches a short drive in most directions; pets are by arrangement there. The Pembrokeshire destination page carries the current listings. As with any coast, read what “sea view” and “beach access” actually mean on each listing — a five-minute stroll and a steep path with steps are both described that way — and our questions-to-ask guide lists the rest of what to confirm before a deposit.

Skomer, seals and the wild bits

The wildlife here is a reason to come rather than a footnote. Skomer Island, off the western tip of the county, is one of the great seabird colonies in the UK; the Wildlife Trust of South and West Wales counted a record 52,019 puffins there in its 2026 census, up from 43,626 the year before. Boats leave from Martin’s Haven roughly April to July and landing numbers are limited each day, so for a group it is a book-ahead set-piece rather than a spontaneous outing. Grey seals pup on the beaches in autumn, and coasteering — a sport invented on this coast — and sea kayaking are run by local operators for groups of all abilities. One of these, placed before dinner, is the shape of a good Pembrokeshire day; our activities and entertainment guide explains why one set-piece beats three.

Seasons on the coast

May to September gives you the beaches and the sea at their best, and the towns at their busiest, though “busy” here is relative. April brings the coast path into flower and the puffins back to Skomer. Autumn empties the beaches, fills the seas and suits a house with a hot tub better than a house built around a barbecue. Winter is genuinely wild and genuinely quiet — wonderful for a group that wants the drama and a games room, less so for one that came for the sand. The west of Wales is wetter than the south-west of England on the Met Office’s 1991–2020 averages, which is not a reason to avoid it but is a reason to apply the rainy-day test to any house you shortlist: our rainy-day group house guide sets out what to check.

Beyond Pembrokeshire: the Snowdonia coast and Mid Wales

West Wales does not stop at the county line. Two hours north, Ty Gwyn at Llwyngwril sits on the Cardigan Bay coast looking out over the sea and the mountains of Snowdonia at once, sleeping 30 with a hot tub, games room and cinema room — the sensible kit for a stretch where Met Office averages put the old county of Merionethshire at 1,914 mm of rain a year and the mountain sites well above four metres. Inland, Glyngynwydd near Llanidloes stands in twelve acres of Mid Wales valley among hills, lakes and rivers, sleeping 33 across sixteen bedrooms with dogs welcome and a wedding barn on site. Neither is Pembrokeshire, and neither is trying to be: they are the answer for a group that wants Wales without the drive to its furthest corner, or that wants mountains with the sea. Our Wales region page and Snowdonia destination page carry the live listings for each.

Structuring a West Wales weekend

Arrive Friday with the big shop done and do nothing organised beyond dinner; the drive has earned it. Saturday, one set-piece — the coast path from the door, a Skomer boat, a coasteering session — placed so everyone is back and showered before the evening, which is when a private chef arriving at the house repays the cost of the whole weekend in not having to find a restaurant for twenty in a small harbour town. Sunday is the beach if the weather allows and the games room if it does not, then the long drive home with the sea behind you. For the dog contingent, our dog-friendly group house guide covers the questions to settle first; for the rest, browse the houses and start with the coast.
