Männlichen is a mountain in the Jungfrau Region that offers stunning 360° views of the Bernese Alps. You can reach it by cable car from Wengen or gondola from Grindelwald Terminal. The ride up is a treat, especially in summer when you can hop on the open cable car roof for the "Royal Ride" experience. Once at the top, you'll be treated to panoramic vistas of the Eiger, Mönch, and Jungfrau peaks.
You'll find a restaurant, playground, open green space, & tons of trails. Plan to spend at least half a day here. We spent a about an hour playing on the playground, then had a picnic on the green space, got an ice cream at the restaurant, & then set out on the kid's trail. All of that took about 4 hours & we still felt like we could've spent several more hours taking in those views. It's definitely a must-visit spot for any mountain lover in Switzerland!
