On the eastern edge of Carirngorms National Park lies a geological marvel and a former hiding place for bandits. Burn O’Vat is as appealing to adults as children, and while a little bit of scrambling over rocks and unleashing your inner Indiana Jones might be required, the walk is well worth it. The visitor centre and its interactive displays will give you an insight into how Burn O’Vat came about 16,000 years ago – the melting of a glacial ice sheet and the resulting meltwater eroding the rock. Then, follow the Vat Burn upstream until it opens out into a stunning 18-metre wide pothole. Red granite gravel covers the base, granite walls tower above, while a mesmerising waterfall cascades down.
