A 4am hike up Yr Wyddfa (Snowdon) has left one man in awe after he witnessed a spectacular cloud inversion at the summit. Callum Heinrich set off in freezing minus four conditions on December 29, reaching the top to see what he described as the 'greatest sunrise and cloud inversion I’ve ever witnessed'.
In a video shared on his Instagram page, @callumzheinrich, Heinrich is seen alongside other early-morning hikers as the sun rises over a sea of rolling clouds. He said: 'I don’t think I’ll ever get over this inversion', adding that 'Snowdon for sunrise is a bucket list moment'.
A cloud inversion occurs when a cold layer of air becomes trapped at ground level beneath warmer air, creating a thick blanket of mist that walkers at higher altitudes can climb above. The phenomenon has stayed with Heinrich well into 2026, as he continues to reflect on the beauty of the natural world.
Commenting on his post, one user said: 'Best view I’ve had from the summit… I was there the same day as you, mate.' Another added: 'That is amazing.' A third wrote: 'Can we be friends? I need people like you guys in my life.'
In a separate post, Heinrich also shared 13 tips for beginner hikers, including advice on clothing materials, foot care, and the importance of checking weather conditions. He emphasised that expensive gear does not make a better hiker and that the summit is only halfway—most accidents happen on the descent.
