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).

Typical rural stone built bridge in a gorgeous country setting. Cycling along these back lanes and seeing these structures is like being in an open air museum.

The road from Bala Lake to Lake Vyrnwy is simply one of the most challenging, scenic and highest rides through the Welsh mountains. If you’re fit enough you will find it one of the greatest rides in the British Isles.

Coed y Brenin was Britain's first purpose-built mountain biking center and it remains one of the sport's top destinations. Eight purpose-built mountain bike trails start at the visitor center and range from easy trails for families and beginners to technical trails for experienced mountain bikers. Other facilities for mountain bikers include a bike shop and a skills room where you can develop your riding techniques. The visitor center is also the starting point for walking and running trails through the Coed y Brenin Forest Park, as well as orienteering courses and geocaching. Two of the walking routes are suitable for visitors who use an off-road mobility scooter. There are also children's play areas, a café and plenty of picnic tables.

This picnic spot provides lovely views across Llyn Trawsfynydd and the surrounding mountains. The lake is artificial, created in the 1920s to supply the Maentwrog power station, though it later became the cooling water source for the Trawsfynydd nuclear power station. It's slightly larger than Llyn Tegid (Lake Bala), Wales' largest natural lake.

This is a lovely viewpoint above the popular hiking and mountain biking trails of the Coed y Brenin Forest. Rising across the valley of the Afon Eden rises Y Garn, an outlier of the ancient Rhinogydd. The main peaks of the range can be seen beyond, with Rhinog Fawr's squat pyramid looking particularly impressive.
