Ty Mawr Group Accommodation

A grand manor house for big gatherings on Anglesey

Ty Mawr is a handsome eight-bedroom manor house at Penmon, on the quiet eastern tip of Anglesey just beyond Beaumaris. Sleeping up to eighteen guests, it forms the largest property within the Tros Yr Afon collection of holiday homes, and it is built for the occasions when the whole family — or a big group of friends — wants to be together under one roof. Reunions, milestone birthdays, anniversaries and relaxed group holidays all suit it perfectly, with plenty of room to gather and just as much space to find a quiet corner.

Room for the whole party

The manor house has eight bedrooms arranged over a generous, characterful interior, with comfortable living and dining spaces designed for a large group to eat, relax and socialise together. The kitchen is well equipped for self-catering on a proper scale, with oven, hob, microwave, fridge and the usual essentials, so preparing meals for a full house is straightforward. With self-catering freedom, you can come and go as you please and set your own pace for the week.

Grounds, gardens and facilities

Guests at Ty Mawr enjoy the wider Tros Yr Afon estate, which extends to around six acres of gardens and woodland — space for children to play and for everyone to stretch out on a fine day. There is a tennis court for friendly matches and barbecue facilities for long summer evenings outdoors. Free on-site parking means there is no shortage of room for several cars, and free WiFi keeps everyone connected. Heating runs throughout, and the house is non-smoking. Well-behaved pets are welcome on request, so the family dog need not miss out — just mention it when you enquire, as charges may apply.

Penmon, Beaumaris and the east coast

Penmon sits at the north-eastern corner of Anglesey, a peaceful spot known for its ancient priory, dovecote and the Trwyn Du lighthouse looking across to Puffin Island. The historic town of Beaumaris, with its UNESCO World Heritage castle, pier and waterfront on the Menai Strait, is around a six-minute drive away, and Bangor is roughly ten miles on. From here the rest of the island opens up — the beaches at Benllech and Lligwy, the fishing village of Moelfre and miles of the Anglesey Coastal Path.

Ideal for celebrations and reunions

A house of this size is hard to find on Anglesey, which makes Ty Mawr a popular choice for the occasions that bring everyone together. With eighteen beds, generous shared living space and the privacy of its own grounds, it lends itself to milestone birthdays, anniversaries, family reunions and relaxed group holidays — the kind of break where cooking together and spending the evening around one big table are half the pleasure. The peaceful Penmon setting, away from any crowds, means a large group can enjoy each other’s company without disturbing the neighbours, and there is plenty of space outside for children to play and dogs to roam.
