This difficult touring bicycle loop from Dolgellau takes you on a demanding 29.9 miles (48.2 km) ride through Eryri / Snowdonia National Park. You will gain 2872 feet (875 metres) in elevation, typically completing the route in about 3 hours and 36 minutes. Expect spectacular views of the Cregennan Lakes, Cadair Idris, and the Mawddach Estuary, with glimpses of Barmouth and the Irish Sea, as you navigate woodlands, farm fields, and dramatic mountain terrain.

Be prepared for a hard bike ride that requires very good fitness, as the route includes significant unpaved and rough sections, especially on the ascent over Cadair Idris. The surface can be gravelly and potholed, transitioning to rocks near the top, making a gravel bike or sturdy touring bike essential. You will also encounter steep gradients up to 20% and multiple gates that require dismounting.

The trail is notable for combining its physical challenge with immensely rewarding vistas, including a section of the National Cycle Network (NCN 82) offering outstanding views over Cardigan Bay. The climb to Cregennan Lake is particularly memorable, featuring a brutal 20% ramp that passes Arthog Waterfalls before opening up to panoramic views. This route offers a profound immersion into the wild beauty of Eryri / Snowdonia National Park.

The road to the Cregennan lakes is narrow and winding, you have to open and close a gate across the road yourself twice. At the end there is a reasonably large parking lot. Don't be put off by the access road and it is wonderful there!

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.

Good loop. I rode up out of Llanuwchllyn. But this ride would work very well starting in Bala. The section up around Arenig is great. A few gates to open/close, one farm to go through....but this is a good alternative to the sadly hobbled Bala Loop (Vyrnwy).

a great castle to explore with views over the se and the Llyn peninsula. It has an informative video that explains its history and then a walk across the bridge that leads you through the fortifications. you can then explore all the rooms that have exhibits of the castles history within them. to finish off you can climb the tower to see the view. Great for kids as there is a park next to it and a cafe across the bridge to keep everyone happy. Parking is available on site but it is a small carpark.

For the circular route around Allt-lwyd there are some boulder like sections very difficult on a gravel bike on the north side climb. I’d recommend using the other south side of the hill for the climb (tarmac to top) and at least the worst sections can be done downhill. You’ll still have one tricky uphill bit though. Can get wet w/ deep puddles after extended rain.
