The lay of the land
Switzerland is landlocked, wrapped entirely by its neighbours, so every crossing is a land border. Overland travel is natural here. Sea and beach days mean a hop to the coast.
Everything you need for Switzerland, sorted before you land: data, visa, insurance and lounges.

Trains that run like clockwork past lakes and four-thousand-metre peaks. Switzerland is expensive: roaming doubly so, which is why travelers here land already connected.

Skip roaming charges and airport-SIM queues: an Ozu eSIM installs before you fly and switches on the second you land. Plans run from 1 GB to 50 GB, valid up to 90 days, with unlimited day passes for longer stays. It runs on local networks, so there’s no bill shock when you get home.
Summer in Switzerland lands between June and August, and the prices and the queues come with it. If you can pick, May or September give you the same place with fewer people and less heat.
Read your card’s small print before you go: many charge a fee on every purchase in another currency, and it piles up where you don’t see it. Carry a second card in a different pocket too: the day the first one gets blocked, you’ll want a plan B.
Airlines check for an onward or return ticket at the desk, not the border, and they’ll refuse boarding without one where the rules ask for it. Have the exit booked, or at least printed, before you get to check-in.
Get the address written down in the local script before you need it: the hotel will do it in ten seconds. A driver reading his own alphabet beats any pronunciation attempt, and it works with a flat battery.

7 lounges across Switzerland's main airports. Skip the terminal chaos at Switzerland’s main airports: pay-per-visit lounges with coffee, wifi, showers and quiet. Whatever airline or class you fly.
