This was my fifth time skiing in Grandvalira area. I am an experienced older skier and love the Pyrenees and this is why I returned to Grandvalira again. I have skied in many parts of the world. This year for the first time in my long skiing career on my first day a young snowboarder speeding at a ca 50 km/hr skied on the back of my skis. This stopped me immediately with my body flying forward and then hitting the ground with considerable force. I was understandably shocked but sustained no injuries. The snowboarder disappeared and was probably unaware of the consequences of his behaviour. I reckon if a heavy snowboarder collided with my body, rather than over my skis, you would not be reading this review and the likelihood of a serious injury or fatality would have been high. On the fourth day of skiing a snowboarder hit me from behind and we both fell on the ground. This was in an area near a chairlift where there were clear signs on the slope advising skiers and snowboarders to pay attention and slow down. Grandvalira ski area authority should perhaps consider increasing the number of effective patrolling personnel similar to the USA resorts. It might increase safety if the number of signs alerting skiers to slow down were increased. I would question the sales of alcoholic beverages at lunchtime. Driving under the influence of alcohol is dangerous and is a crime. Skiing whilst inebriated too. I was very surprised that the first language on the signs on some slopes was Russian above Catalan!(e.g at the bottom of the Rossinyol slope).I encountered many Russians with whom I spoke. One couple came directly from Moscow and were vociferously pro Putin and the war. This was in the week when Ursula von der Leyen, the President of the European Commission, met President Zelensky and spoke about increasing sanctions against Russia. What are the Andorran authorities doing in this regard? As usual, the slopes were extremely well groomed and the staff in the cafes and restaurants very friendly. I was fortunate to have only one day of poor visibility and heavy snow during my holiday. Thank you for your attention.
