January 27, 2026, Carnedd Llewelyn Summit

A very fine mountain that is the high point of the Carneddau range. These mountains are high, remote and so much quieter than the Glyderau or Snowdon. Fabulous walking country.

Carnedd Llewelyn is high and relatively remote, so walks there are quite a serious undertaking.

As the previous person said, it is very very wet on the outward path from the bothy. If you do decide to go anyways, make sure to have a walking stick or similar to stabilise you and determine the depth of the water before sticking your foot in it.

June 11, 2025, Coedty Reservoir

The reservoir was originally built in 1924 to supply water for the hydro-electric power station in Dolgarrog, which in turn powered an aluminium smelting works. This power station is still operational today. Coedty Reservoir is historically significant due to its involvement in the devastating Dolgarrog Dam Disaster of 1925. The failure of the Llyn Eigiau dam, located upstream, led to a surge of water that also breached the Coedty dam. This resulted in a catastrophic flood that swept through the village of Dolgarrog, causing the loss of 16 lives. Coedty dam is a "balance tip" dam, meaning water flows from it automatically when it reaches high levels. This excess water flows into a spectacular gorge below, which is used by outdoor pursuit groups. However, gorge walking here can be dangerous due to the sudden releases of water.

The sobering part was reading how they thought it was safe after hearing the church bells. They weren't, it was the church getting swept away!!!!

The worst part of any hike ever. I had to carry on going up, creating my own path, through trees, scrambling up mudfalls, rock climbing with no ropes. it's all collapsed.

Many of the best routes in the area are circular. For a moderate loop that explores the area's reservoirs, the Yellow Lake – Dulyn Reservoir loop is a great choice. It's just under 6 miles (9.3 km) and offers fantastic views without being overly strenuous.

Can I bring my dog on the hikes around Dolgarrog?

Dolgarrog is generally a dog-friendly area, but be aware that you'll be hiking in Snowdonia National Park where sheep grazing is common. Dogs should be kept on a lead, especially on open moorland and near livestock. The woodland trails in places like Gwydir Forest Park are often excellent for walks with dogs.

Are there any easy, family-friendly walks in the area?

Where can I find hikes with waterfalls near Dolgarrog?

The area is known for its water features. A popular walk is to Pont Dolgarrog, which provides views of the impressive Afon Ddu waterfalls. For another option, the nearby Fairy Falls (Rhaeadr Y Tylwyth Teg) in Trefriw is a well-loved spot, though parking can be limited.

What is the history of the Dolgarrog dam disaster?

The area holds a significant piece of industrial history. In 1925, the Eigiau Dam breached after heavy rainfall, causing a cascade failure of the Coedty Reservoir dam below. This resulted in a devastating flood in the village of Dolgarrog. Many walking routes pass the poignant ruins of the old dam wall, serving as a memorial to the event.

For experienced hikers seeking a tough day in the mountains, the View of Ffynnon Llugwy – Carnedd Llewelyn loop is a demanding option. This 10.5-mile (16.9 km) route involves a significant ascent of over 940 meters to the summit of Carnedd Llewelyn, the highest peak in the Carneddau range.

Where is the best place to park for walks around Dolgarrog?

Parking can be found within the village of Dolgarrog itself, which serves as a good starting point for many trails. For hikes heading towards Llyn Eigiau and Carnedd Llewelyn, there is a car park at the end of the public road in the Eigiau valley. Always arrive early, especially on weekends, as spaces are limited and fill up quickly.

Are there any pubs or cafes for after a hike?

While Dolgarrog itself is small, the nearby towns of Trefriw and Llanrwst in the Conwy Valley offer several pubs, cafes, and restaurants. They are just a short drive away and provide great options for a post-hike meal or drink.
