Stone house and chapel in Ganllwyd
The village includes Dolmelynllyn Hall (now a Hotel and owned by the National Trust), and the area is also referred to as Dolmelynllyn. One author suggests an Arthurian link to the village but there is no other corroboration.
The village, which lies where the old Roman road used to ford the old River Eden just before it joins with the rivers Mawddach and River Gamlan has three large waterfalls and many smaller ones all within Coed-y-Brenin (the forest of the king).
The village is now surrounded by Forestry Commission and National Trust parkland of conifers and oaks. A large area of surrounding ancient oak woodland is a designated Site of Special Scientific Interest and has a particularly rich temperate maritime Bryophyte community. The forest has a group of Wellingtonia planted in the early 20th century and Dolmelynllyn has two trees dating from the 1850s in the meadow, one being the second largest in Wales. The forests are full of wildlife, with deer, red squirrels, pine martens, polecats, otters, and other mammals, and a variety of birds from black grouse to merlins, buzzards, and red kites. There are many walks from the village into the forest, and several free car parks.building it up.
