About Plas yn Rhiw
Plas yn Rhiw (Mansion on the Hillside) is a small manor house on the southern shore of the Llŷn Peninsula, set on the hillside above Hell's Mouth — the 4-mile surf beach of Porth Neigwl — with views south over Cardigan Bay and north-east to the peaks of Snowdonia. The house has 16th-century origins with later additions; the garden, a series of terraced compartments descending from the house, is one of the finest smaller gardens in Wales and the main reason to visit.
The property owes its survival to three sisters — Eileen, Lorna, and Honora Keating — who discovered the derelict house in the late 1930s and spent decades restoring it. They were accomplished plantswoman and conservationists who also helped protect the Llŷn Peninsula from inappropriate development, contributing to its designation as an Area of Outstanding Natural Beauty. The Keatings bequeathed Plas yn Rhiw to the National Trust in 1952, and the property retains the intimate, personal atmosphere of their stewardship.
The garden is at its most spectacular in spring: snowdrops in late winter, daffodils in March, and bluebells in April and May. The mild Llŷn climate supports tender plants that would not survive further inland. Mynydd Rhiw — the upland viewpoint with Bronze Age cairns — rises directly behind the house and is accessible on foot from the property. Aberdaron village, at the tip of the peninsula, is 4 miles west.

Frequently asked questions
<span lang="cy">Plas yn Rhiw</span> (Mansion on the Hillside) is a small manor house and garden owned by the National Trust on the southern shore of the <span lang="cy">Llŷn</span> Peninsula, above the long surf beach of Hell's Mouth (Porth Neigwl). The house dates in part from the 16th century, with later additions. Its garden — a mixture of formal terracing, woodland, and wild planting — is regarded as one of the finest smaller gardens in Wales. The property is special partly for the dramatic setting and partly for the story of the women who saved it.
<span lang="cy">Plas yn Rhiw</span> was rescued from dereliction in the late 1930s by three sisters — Eileen, Lorna, and Honora Keating — who fell in love with the neglected property and spent decades restoring the house and garden. The sisters were passionate conservationists who also fought to prevent the development of the <span lang="cy">Llŷn</span> Peninsula, helping to establish it as an Area of Outstanding Natural Beauty. They bequeathed the property to the National Trust in 1952. Their story is told in displays within the house.
The garden at <span lang="cy">Plas yn Rhiw</span> is informal and plantswoman's in character — a series of terraced compartments stepping down from the house, with box-edged beds, snowdrop displays in late winter, bluebell wood in spring, and an eclectic collection of plants including some tender species that thrive in the mild <span lang="cy">Llŷn</span> climate. The view from the upper terrace over Hell's Mouth to the south is outstanding on clear days. The garden is at its most dramatic in spring when snowdrops, then daffodils, then bluebells flower in sequence.
The garden and the headland around <span lang="cy">Plas yn Rhiw</span> overlook Hell's Mouth (Porth Neigwl) — a 4-mile surf beach on the south coast of the <span lang="cy">Llŷn</span> Peninsula. The views from the upper garden extend south across Cardigan Bay, with the cliffs of Ceredigion visible on clear days. Looking north-east, the peaks of Snowdonia are visible above the body of the peninsula. <span lang="cy">Mynydd Rhiw</span> — the upland viewpoint immediately behind the house — gives even wider views and can be walked from the property.
<span lang="cy">Plas yn Rhiw</span> is open from mid-March to October. The garden is at its finest in spring — snowdrops typically appear in February (before the property opens), followed by daffodils and then bluebells in April and early May. Summer is beautiful but the garden is perhaps less dramatic than in spring. The autumn garden can also be good, with foliage colour in the woodland sections. Check the National Trust website for opening days — the property is not open every day.
