This route was planned by komoot.
This route is classified as difficult for racebike cyclists. It features significant climbs, particularly the Sychnant Pass itself, which has sections with average gradients up to 12.5%. The broader Conwy Valley also includes demanding ascents, requiring very good fitness.
The Sychnant Pass is a challenging climb with steep gradients. The road at the summit is notably narrow, and visibility can be restricted by deep shade and low-level sunshine. While surfaces are generally well-maintained, cyclists should be prepared for close encounters with motor vehicles, horses, and walkers due to the lack of designated cycling space.
Given its 'difficult' grading and significant elevation gain of over 1000 meters, this route is generally not recommended for beginner road cyclists. It requires a good level of fitness and experience with challenging climbs and narrow road conditions.
While specific parking details for a loop starting precisely in Bethesda are not provided, Bethesda serves as a good starting point for exploring the region. You would typically look for public parking facilities within Bethesda itself to begin your ride.
You'll experience breathtaking dramatic landscapes and panoramic views throughout the route. Highlights include the stunning Llyn Ogwen, the challenging Sychnant Pass Climb from Capelulo, and views of the Carneddau Mountains, Conwy Estuary, and majestic Conwy Castle. The pass itself offers a mix of rolling hills, steep cliffs, and lush valleys.
The scenery changes with the seasons, from vibrant greens in spring and summer to rich reds and golds in autumn. Spring, summer, and early autumn generally offer the most favorable weather conditions for cycling, though you should always check local forecasts for wind and rain, especially in mountainous areas.
This is a road cycling route that primarily uses public roads. While there are no specific restrictions against dogs on public roads, it's generally not advisable to bring dogs on a racebike route of this difficulty and length due to safety concerns for both the dog and the cyclist, especially on narrow sections like Sychnant Pass.
No, you do not need any special permits or to pay an entrance fee to cycle this route. The route primarily uses public roads within Eryri National Park (Snowdonia), which are freely accessible. However, standard road cycling regulations apply.
As this route is within Eryri National Park (Snowdonia), cyclists should adhere to the Highway Code and respect other road users. While there are no specific cycling permits required for public roads, always be mindful of local wildlife, keep noise to a minimum, and leave no trace. Be aware that some sections of the route, particularly the Sychnant Pass, are narrow and shared with motor vehicles, horses, and walkers.
Yes, the route passes by Siabod Cafe, which is a good option for a break. The Conwy Valley area also has various cafes, pubs, and accommodation options, particularly in towns like Betws-y-Coed, which you might pass through or near depending on your exact loop.
Yes, the route intersects with several other paths. Notably, it covers significant sections of the Conwy Valley Cycle Route (29%), Snowdonia Slate Trail (18%), and National Cycle Network Route 5 (15%). Smaller portions also overlap with the Wales Coast Path (North Wales Coast) and National Cycle Network National Route 82.
The social ride of Rhos On Sea cycle club led by Alan took us to Betws y Coed but John Paul Jones and I extended the route around the spectacular Ffrancon which we never tire of.
