Embark on the Mach 1, 2, and 3 Loop, a difficult gravel biking adventure spanning 30.4 miles (48.8 km) with a significant 3067 feet (935 metres) of elevation gain. This route takes you deep into the Plynlimon mountains, offering a true sense of wilderness and isolation. You'll navigate open, exposed trails that provide expansive views of forestry, valleys, and distant peaks. Keep an eye out for red kites soaring above, particularly along the Valley Balcony Gravel Track, a highlight of this nearly 4-hour and 44-minute journey. The combination of three distinct loops ensures a comprehensive experience.

Planning for this difficult route requires preparation. The Mach 1, 2, and 3 Loop primarily follows natural tracks and gravel roads, leading you into remote areas. Specifically, the Mach 3 section ventures deep into the Northern Cambrian Mountains, where services are non-existent. Make sure to pack ample snacks and water, as you won't find any refueling options along the way. A strong level of fitness and good mountain-sense are essential to safely complete this challenging gravel biking experience.

This route stands out for its comprehensive exploration of the Welsh mountains, combining three distinct loops into one challenging ride. It offers a unique opportunity to experience the wild beauty of the Plynlimon range, with its varied terrain and sweeping vistas. The trail's remote nature means you will encounter few others, allowing for a truly immersive journey through this rugged landscape.

First, a somewhat adventurous ride on the single track to the parking lot, which costs £5. The easy loop around the lake is very beautiful and relaxing – the sheep roam freely, but they keep their distance. Dogs must be on a leash, of course, but that's not a problem. Enjoy it – and if you're up for more, go for a longer loop. There are a few tables and benches above the parking lot for your picnic. You won't find any litter baskets, so you'll have to take them with you – which is perfectly fine, as it's a nature reserve. Highly recommended.
