Llyn Padarn lake, Snowdonia, Wales

From sparkling llyns, mountain hikes, cascading waterfalls to ruined castles, Snowdonia never ceases to amaze. Pictured here is Llyn Padarn, near the charming village of Llanberis. At about 3.2 kilometres in length and 29 metres in depth, this glacial lake is one of the largest natural lakes in Wales. This example of a moraine-dammed lake has been designated as both a Site of Special Scientific Interest and a bathing water. Whether you're an enthusiast of kayaking, paddleboarding or simply want to immerse your toes in the water, it has your back. In addition, its shores are dotted with remnants of slate quarries, providing a glimpse into the region's industrial past. While you're there, don't forget to explore the nearby Dolbadarn Castle, a historic gem that adds an extra layer of antiquity to your journey.
