Aber Falls (known in Welsh as Rhaeadr Fawr, meaning 'big waterfall') is a stunning waterfall located in the foothills of the Carneddau range, about 3 km south of the village of Abergwyngregyn in Gwynedd, North Wales. It's a highly popular tourist destination within Snowdonia National Park. Beauty: The falls are beautiful in all seasons, but are particularly spectacular after heavy rain, especially in autumn and winter, when the water flow is at its most powerful. Plunge Pool: There's a shallow rocky plunge pool at the base of the falls, where some brave visitors even take a dip (though the water is very cold!). Rhaeadr Bach: A short distance to the west, there's a second, smaller waterfall called Rhaeadr Fach (or Rhaeadr-bach).

Approaching from the north it is a slog on the bike but nothing technical. With the right gearing and fitness it's all rideable if you're happy to take your time and plod.

This is a serene lake located in the Conwy Valley surrounded by forested hills and the rugged landscape of Snowdonia. There's a cafe and fishery further south along the lake which is a lovely place to stop and refuel.
