Sunny delight - bring your sunglasses
Sunglasses are well recommended if you intend to go up the mountains - the sun on the snow can dazzle you a lot and slowblindness can occur. Sturdy shoes, preferably water and snowproof are adviseable. No real things you should bring - the pharmacies usually have at least one open during the night. If you go out drinking though, a really supply of aspirin or alka-seltzer is adviseable.
