Cycle Ride to

Cwm Pennant (Pennant Valley) & Porthmadog from Dolbenmaen

    This is possibly the best cycle route in north Wales for seeing a variety of spectacular mountain views from quiet lanes. Snowdonia is of course rich in mountain scenery, but for a cyclist much of it can only be seen from main roads. Though this ride is mostly along untrafficked country lanes, unfortunately, for linking purposes, there is nearly a mile on the A487 trunk road towards the end. There is also a mile and a half along the A4085, but usually this is not a very busy road.

    The ride includes a there and back trip along the enchanting Pennant Valley, one of the hidden treasures of North Wales. Among the excellent mountain views to be relished on this ride are those of the Hebog range, the Nantlle ridge, Cnicht and the Moelwyns and the Snowdon massif. There is also a lofty view of the Madog estuary. It is recommended to choose a fine, clear day in order to savour the scenery to the full!

    A mountain ride necessarily has a fair amount of ascending (900m in this case) but here the gradients are mostly moderate and are never severe. The descent to Prenteg, however, is both steep and long with a succession of bends. It is essential to exercise caution and have brakes that are in good order.

    A bonus during the nesting season is the opportunity to see a pair of ospreys at the RSPB's Glaslyn Osprey Project (free entry).

Route: Dolbenmaen - Cwm Pennant - Brynkir - Prenteg - Garreg - Penrhyndeudraeth - Porthmadog - Penmorfa - Dolbenmaen

Distance: 32 miles

Ascent: 900 metres. There is a fairly steep climb soon after entering the Pennant valley, but most of the ascents are only moderate; low gears, however, are desirable. Good brakes and caution are also in order for the very steep, winding descent to Prenteg.

Start: Unmade layby on a lane near Dolbenmaen (Grid Ref: 503432 OS 50,000 map No 124 Porthmadog and Dolgellau). Coming from the Caernarfon direction Turn 2nd Left after Bryncir, signposted Garndolbenmaen (Caution - the first Left Turn after Bryncir is also signposted Garndobenmaen). The wide layby is less than 100 yards on the Right.
