| Lake Orta |  |
| Region of Piedmont (Italy) - Parallel to Lake Maggiore, Lake Orta is located on the road from Domodossola to Novara. It is the westernmost of the Alpine lakes created by the Simplon glacier after the last ice age some twenty thousand years ago. |
| Oberalp | |
| Uri/Graubünden - Oberalp Pass, in the Swiss Alps, is the high mountain pass (2046m over sea level) connecting the cantons of Uri (Central Switzerland) and Graubünden (Southeastern Switzerland) between Andermatt and Disentis. |
| Ollon (VS) | |
| Canton of Valais (Switzerland) - It bears the same name as a famous wine-growing village in the Chablais region of Vaud and, like it, nestles in the heart of the vineyards, but it is a pretty Valais village perched on the sunny slopes of the right bank of the Rhône, halfway between Saint-Léonard and Sierre. |
| Olten | |
| Canton of Solothurn (Switzerland) - Olten, situated on the River Aare, is the largest city in the canton of Solothurn, but it is much less touristy than the canton's baroque capital. Its great asset is a tiny old town that is well worth a visit. |
