My husband and I are planning a 7–9 day trip to Switzerland in late August/early September 2026, with a focus on day hiking in the Bernese Oberland region. We’d love recommendations from anyone who has done a similar trip—especially regarding accommodations, favorite hikes, and getting around. We’re debating whether to stay in one location the entire time or split our stay between two or three bases. Wengen and Mürren are currently at the top of our list. Are those good choices, or are there other places we should consider?
