Can you pls adv if i take from interlaken to grindewald and take the gondola and also the wengel aerial cable car ,would there be enough time to reach jungfrau.
I think this is how you want to travel: Grindelwald - Männlichen - Wengen - Jungfraujoch, right? In that case: yes, that's doable if you start early. Do check weather forecasts shortly before and plan your Jungfraujoch visit at the time of the day when skies are most clear. On typical summer days, this is in the early morning (no guarantees of course). You can also make the trip you have in mind in the reverse order, after the Jungfraujoch. The timetable will help you find details on all connections.
