This route was planned by komoot.
This hike is generally rated as moderate to hard or strenuous. It's not recommended for inexperienced walkers due to its demanding nature, including steep ascents and descents, and sections that may involve scrambling. Good fitness and some countryside walking experience are essential.
The terrain is famously rugged and challenging. You'll encounter craggy peaks, windswept moorlands, and upland heath. Paths can be steep, rocky, and often indistinct, especially during descents. Expect concealed boulders, deep heather, and potentially wet and boggy sections. Summit approaches often involve loose scree and boulder clambering. While some parts follow ancient packhorse routes like the "Roman Steps", much of it is a "vast natural 'rockery'".
The loop offers superb remote scenery and extensive views. You'll pass the picturesque Pistyll Gwyn Waterfall and the wonderful mountain lake Llyn Du (Rhinog Fawr). The Rhinog Fawr Summit Cairn provides panoramic views over surrounding peaks, Cardigan Bay, and the Llŷn Peninsula. From Bwlch Drws Ardudwy, there are grand views across to Lake Trawsfynydd and the Arenigs.
Specific parking details are not provided in the tour data, but trailheads in this remote area typically have limited parking. It's advisable to research local parking options near the start of the loop, such as lay-bys or small car parks, before your visit. Arriving early is often recommended, especially during peak season.
Yes, dogs are generally allowed on this trail. However, as the route passes through the Rhinog National Nature Reserve, which is home to important habitats and species including feral goats, it is crucial to keep dogs under close control, preferably on a leash, to protect wildlife and livestock.
The best time to hike is typically during the drier months, from late spring to early autumn (May to October), when weather conditions are more stable. However, even then, be prepared for changeable mountain weather. Winter hiking is possible for experienced individuals but requires specialist gear and skills due to snow, ice, and extreme conditions.
No, there are no specific permits or entrance fees required to hike the Rhinog Fawr and Bwlch Drws Ardudwy loop, even though it passes through the Rhinog National Nature Reserve. Access to the reserve is generally free and open to the public, but visitors are expected to follow the Countryside Code.
Yes, sections of this route coincide with other established paths. Approximately 46% of the loop follows part of the Cambrian Way, and about 4% utilizes the historic Roman Steps, which is actually a medieval packhorse route.
Given the rugged and challenging nature of the terrain, sturdy, waterproof hiking boots with good ankle support are highly recommended. Due to potentially indistinct paths and challenging navigation, especially in poor visibility, carrying a map and compass (and knowing how to use them) is essential. Layered clothing, waterproofs, sufficient food and water, and a first-aid kit are also crucial.
No, this loop is generally not recommended for inexperienced walkers, families with young children, or beginners. Its demanding nature, including steep, rocky, and potentially boggy terrain, requires good fitness, navigation skills, and prior countryside walking experience. There are more suitable, less challenging trails elsewhere in Snowdonia for those new to hiking.
The Rhinogydd mountain range, where this loop is located, is often referred to as one of the "last true wildernesses in Wales." This means you can expect a truly untamed hiking experience with fewer crowds compared to more popular areas of Snowdonia National Park, offering a sense of wild isolation.
Just went up one of the Rhinogs with a couple of friends on a lovely day
Absolutely melting hot today hiking around the Rhinogs..even went swimming in the lake halfway up..also saw two lizards basking on the path before the bolted off into the undergrowth ...great hike just too darn 🔥
Lovely hike & scramble upto the trig via Pistyll Gwyn,, I wouldn't recommend doing the circular route we did as its quite boring & a hard slog!
