Start: Bethania carpark, grid ref: SH599489

  1. Start at the car park on the A498, near Bethania. Take the Watkin Path (eventually leads to Snowdons summit) on the other side of the road heading north with an oak woodland on your left.

  2. Once you rise above the woodland, you are greeted by a wonderful view of the Afon Cwm Llan waterfalls. The ridge to your right is home to many plants, including Juniper.

  4. Continue on this track, passing through a wall before entering Bylchau Terfyn. You are now on National Trust farmland which is managed in an environmentally sensitive way. Welsh black cattle graze this land, keeping it in optimum condition for plants by preventing excessive grow of certain grasses and bushes. A little further on, cross a dry stone wall using the stile.

  5. Walk uphill through heather until you reach the highest point on this walk 344yd (315m). You can see Beddgelert village from here and warnings that there are old copper mine shafts around. Bats live in the old mine workings. Descend the hillside, crossing a stream via stepping stones, and climb over a stile.

  6. Pass a derelict barn (once used to shelter animals) and follow the way-marks to another stile which leads into the Craflwyn estate. Keep on the path until you reach a T-junction, where you turn left and walk down to the estate buildings and car park. To your left is the historic site, Dinas Emrys. Return via bus or along the valley and around Llyn Dinas.

    The Trust acquired Craflwyn in 1994. It had been neglected and required a great deal of restoration. The Victorian mansion has now been converted into a centre where volunteers stay while helping with conservation tasks. You can also hire it for weddings.
