At first I thought they were lingonberries but the bush seems a little high looking at the picture (greater than 30cm).
More mysteries from across the sea?
I'll have a stab at this.
I reckon this might be red elder (Sambucus racemosa) 'cos it looks like an elder at first glance but with red berries in a tighter bunch than our native elder.
Enjoy your travels!
