Embark on a challenging mountain biking adventure through the Penmachno MTB trails, a hidden gem nestled high in Eryri (Snowdonia) National Park. This route offers 17.8 miles (28.6 km) of purpose-built singletrack and forest trails, featuring a mix of fast descents, technical sections, and demanding climbs. You will gain 1944 feet (593 metres) in elevation, passing through ancient woodlands, alongside cascading waterfalls, and enjoying panoramic views across lush valleys and crystal-clear streams. Expect a ride that takes around 2 hours and 52 minutes to complete, graded as moderate but best suited for experienced riders due to its technical nature.
When planning your visit, be aware that the trails are remote, offering a tranquil experience away from crowded biking hubs. The entire 17.8-mile (28.6 km) route can be ridden as one continuous loop, or you can choose to tackle the individual Dolen Machno (19 km) or Dolen Eryri (11 km) loops. Parking is typically available at the trailhead, but always check local information for any specific access details or requirements before you go. The natural setting means you should be prepared for varying weather conditions typical of a national park.
What truly sets the Penmachno trails apart is their raw, natural charm and the community effort behind them. Managed and maintained by Menter Bro Machno, a local group, the trails are funded by rider donations, fostering a sustainable approach to their upkeep. This commitment ensures a unique and authentic mountain biking experience, allowing you to fully immerse yourself in the untouched beauty of Snowdonia without distractions. It is a place where the focus remains purely on the ride and the stunning natural environment.

The carpark is very limited & only open below the barrier at the entrance to the forest. Payment is voluntary via the Penmachno on line page or with cash into the 'glory hole' @money box. The trail is run & maintained by local volunteers (unfortunately I fear they may have long gone). Hot food & good coffee is available 7 days a week at the Conwy Falls Cafe at the Junction with the main A5 road in & out of the village.
