Visas & entry
A guide to Bern highlights the free things worth prioritizing on a budget: the Bear Park along the Aare river costs nothing to visit, and the Rosengarten up the hill offers sweeping views over the Old Town's horseshoe river bend, especially striking at sunset. Their practical tip for a rainy day: Bern's Old Town has about 6km of covered arcades that shelter you from the weather while you browse the boutiques underneath, and the town itself is compact enough that getting properly lost isn't really possible.
