First snow yesterday on Rax. A beautiful day #hiking, with some stormy winds and drizzle while coming down.

68 km from #Vienna to #Tulln and back along the #Danube. Heavy rain was waiting for me there 🥶💦 and accompanied me for quite a few km when coming back, but still happy I went. #cycling

Relaxing family vacation in #Malta in the middle of ancient history. The photo shows the neolithic temple Ħal Tarxien, one of many sights worth of visit.

A shortish bike ride to welcome 2025. Beautiful but cold and unfortunately less than healthy air quality.

A photo taken from the Danube island over the northern part of the river towards Kaisermühlen. There is frost on the ground, and the tops of tall buildings are hidden in white fog/smog.

A great, even if windy, weather for a Saturday bike ride on Donauinsel 🚴
Photo towards Leopoldsberg taken from Donauinsel. A road in the foreground is forked; towards the Leopoldsberg on left and towards the horizon on the right. Leopoldsberg and autumn foliage are on trees and bushes are visible behind the road. The sky is overcast.
