Lower Lliw Reservoir and Café

Highlight • Lake

Great destination and lovely cycling up to the upper reservoir. Some one has taste in the cafe. Orla Keily table cloths.

Tip by

33.7 km

Easy walking along the Eastern and Southern edges of the reservoir, courtesy of the Gower Way (a 35-mile path linking Penller Castell to Rhossili if you fancy stretching your legs a little further).

Fantastic views.

Brynllefrith Plantation Trail

Highlight (Segment) • Trail

Path linking Upper Lliw Reservoir with the road over Mynyddd y Gwair. Forestry track which is firm in places but rutted and muddy in others.

Tip by

Mountain Road Climb

Highlight • Mountain Pass

Expect a tough climb especially after the hills that lead to this point! Perhaps a little “pushing” will be required but nice decent on the other side. Lovely views of your stopping for a “breather”!
