Hard for the grade red downhill track. Drops and more await you as part of the finale to the classic Gwydir trails. Often ridden as part of a shorter ride "mini Marin".

With so many streams crossing the mountain bike trail here at the head of the valley, it's no surprise that there's always a lot of standing water (and flowing water) on the rocky trail here. Waterproof socks would have been a good idea - even in July! The water does add another layer of fun to navigating this nadgery section though, heading wheel-first into puddles of unknown depths!

If you're of a certain age, the name Maryn Trail says it all. One of the original old school trails and still one of the best.

Blaenau Ffestiniog played a huge part in Snowdonia's slate industry, thanks in part to the Ffestiniog Railway, which connected the town to the port of Porthmadog. The remnants of this time tower above the town in the form of dark blue slate waste tips. Some see them as an eyesore, whilst others think they should be celebrated as a great reminder of a once thriving industry. What is not in doubt is that Blaenau Ffestiniog is a magnificent base for adventures in the superb Moelwynion range. Dramatic mountains that make for excellent days out on the hill. Around the town are plenty of other places of interest, from the Llechwedd Slate Caverns to the Antur Stiniog mountain biking trails. Blaenau Ffestiniog is a wonderful town to explore.

Capel Curig is renowned for its natural, rugged mountain biking trails rather than purpose-built bike parks. You can expect significant climbs, technical descents, and varied terrain, all set against the breathtaking backdrop of Snowdonia National Park. Trails like the Gwydir Mawr (formerly Marin Trail) offer a mix of forest roads and challenging singletrack, providing a true mountain bike adventure.
Yes, the area is known for its challenging trails. The Reid ar Ras Descent – Gwydir Mawr & Bach Trails, for example, is a hard red-grade downhill track with drops. The Gwydir Mawr trail itself is a 25km route with big climbs and technical descents, requiring good fitness and advanced skills. The Penmachno Trails also offer fast, technical singletrack and tight switch-backs for an exhilarating ride.
Many trails offer stunning views. The Gwydir Mawr trail provides panoramic views of Snowdon, Tryfan, and the Glyder range on clear days. The Penmachno Trails, particularly the Dolen Eryri loop, are known for their flow and spectacular views within Snowdonia National Park. The wild Pont Banog Trail – Gwydir Mawr (Marin) Trail also offers awesome views after its initial climb.
The Penmachno Trails are often described as a 'hidden gem' of North Wales biking, offering 30km of natural-feeling single-track and scenic forest trails across two loops. Another wild and challenging option is the Llyn Cowlyd Loop, which provides an immersive experience away from the crowds with stunning views around Llyn Cowlyd and Llyn Crafnant.
Many of the natural trails, like the Pont Banog Trail – Gwydir Mawr (Marin) Trail, have no facilities other than parking. It's crucial to be self-sufficient, carrying plenty of hydration, a mobile phone, food, spare tubes, and a chain link. The Penmachno Trails are also in a remote area where phone signal can be limited, so preparation is key.
If you need spare parts or wish to hire a bike, 'Beics Betws' in Betws-y-Coed is a local bike shop that can assist you. For general supplies, Llanrwst is a nearby town where you can grab a bite to eat and support the local economy.
Beyond mountain biking, the Capel Curig area offers a wealth of outdoor activities. You can explore various Mountain Hikes, including challenging routes like the Pen Yr Ole Wen – Carnedd Llewelyn Summit loop. There are also scenic Waterfall hikes, such as the loop around Swallow Falls, and diverse Road Cycling Routes for different skill levels.
Yes, the area has a rich history. Blaenau Ffestiniog, a short distance away, played a significant role in Snowdonia's slate industry. You can visit the Blaenau Ffestiniog and Ffestiniog Railway to see the remnants of this era, including slate waste tips and the historic Ffestiniog Railway. The Llechwedd Slate Caverns are also nearby for a deeper dive into the region's industrial past.
While specific seasonal advice isn't provided, the region's rugged terrain means that clear days offer the best panoramic views. Be prepared for varied weather conditions, as trails like Dal Ali Singletrack can be very wet even in summer. Always check local weather forecasts and dress appropriately for mountain conditions.
Visitors highly appreciate the challenging nature of the trails and the stunning natural beauty. The 'old school' feel of trails like Gwydir Mawr Mountain Bike Trail, combined with recent additions, keeps riders engaged. The sense of adventure, technical sections, and the rewarding views after climbs are frequently highlighted as major draws.
The Gwydir Mawr (Marin) Trail is a challenging red-grade trail. Riders recommend taking spare inner tubes as pinch punctures are common, especially if running low tire pressures. Be prepared for an endless climb at the start, followed by wicked singletrack, awesome views, and plenty of technical sections. The trail has been updated with clear signage and maintains its original feel while increasing the fun factor.
