Llyn Dinas is a picturesque 24-hectare glacial lake in Eryri (Snowdonia) National Park in North Wales, near Beddgelert in the Nant Gwynant valley. It is a popular spot for scenic walks, wild trout fishing, paddleboarding, and swimming. The lake is relatively shallow (maximum 10 metres) and lies on the lower slopes near the Watkin Path to the summit of Snowdon.

A good steep climb finally gives way to a flat top summit with expansive views in all directions. including across the valley to Yr Wyddfa (Snowdon).

Rainbows on mountains tend to be a mixed blessing as they are a pretty sure sign that you are about to get wet! However from the photographers point of view they can also signal some great light, with sun mixed in with dark moody clouds. This was the view from near the summit of Cnicht - otherwise sometimes called the Welsh Matterhorn due to its pointy appearance from the village of Croesor. To the right of the picture is Moel Hebog which rises steeply above the pictuesque village of Beddgelert.

The flat topped summit can be difficult in mist, hard to find the very top, and also to navigate off to find the route to Moelwyn Fach - you have to double back, and then descend to the right.

A fine rocky and in places narrow ridge, and you will often have it all to yourself!

Situated just to the north of Beddgelert, and named after the nearby hill fort of Dinas Emrys, Llyn Dinas is a beautiful, peaceful lake perfect for a walk or even a swim.

Moel Hebog has a rocky surface with a distinctive pointed top, although it appears more rounded from other sides. Due to the exposed rock, it is often visited by geology students. A large part of the mountain consists of tuff. (Wikipedia)

While many natural monuments involve uneven terrain, some areas offer more accessible options. The Glaslyn Estuary features relatively flat paths that can be suitable for prams, and parts of Black Rock Sands beach are accessible, especially with the drive-on access. However, deep gorges and mountain summits are generally not pram or wheelchair friendly due to their challenging nature.
