So let’s store 1 day of power, at 100% efficiency, using the tallest Alp (the Mont Blanc).

Let’s round up to 5000 meters of elevation. We need to store 2.6e18 joules, and 1 joule is 100 grams going up 1 meter. So to power a tiny little country, we need to lift roughly 5e13 kilos up the Mont Blanc. To visualize, that’s 1.7 billion 40ft shipping containers, or roughly 100 per inhabitants.
