歯車の山岳鉄道でユングフラウヨッホまで行き、展望台、レストラン、そしてLindt Swissのチョコレートショップが並ぶ高山の名所、Top of Europeを訪れましょう。あなたのチケットで、あなたは行くにつれて高山の景色を楽しみながら、山の谷を通って移動するでしょう。町が見えなくなると、ミッテルランドの山岳地帯、ヴォージュ山脈、アレッチ氷河の壮大な眺望に迎えられます。出発はインターラーケンオスト、ラウターブルンネン、グリンデルヴァルト、ヴィルダースヴィル、ヴェンゲンの各駅から利用可能です。
First, poor meeting location. Where do you meet the tour? It says "Interlaken." Wow that's not helpful at all. Where in Interlaken? Doesn't say. Nothing. Zip. Nada.
Second, call the Swiss phone number listed on the voucher for help and you get the Jungfrau Bahn which has nothing to do with the tour itself other than selling the train tickets. They can't help you with the meeting place, other than to say that they sell the tickets and who are the popular tour operators.
Third, this tour is not being operated by Viator. It's being resold from Best of Switzerland tours.
Fourth, the tour says it meets at 10:45am in Interlaken. The reason you meet at 10:45am is so all the people from Zurich, Bern and everywhere else can arrive in Interlaken at 10:45am. If you wait until 10:45am to meet the tour you won't be able to get a train until 11:35am. That literally wastes the day. The Jungfrau Bahn leaves Interlaken Ost starting at 6:35am and goes every 30 minutes. It takes two whole hours to get to Jungfraujoch from Interlaken. If you take the 11:35am train your don't get to Jungfraujoch until 1:35pm, so you will need to turn around in just a short time.
Finally, recognize the issue with going so late in the day to the Jungfraujoch is that you will have to deal with huge tour groups, especially the organized ones from China, Taiwan and Korea which tend to be very big.
My suggestion if you stay in Interlaken is to go to the train station as early as you can to go up Jungfraujoch. A round trip ticket costs 210 CHF or about US $212. Go up via Lauterbrunnen and return via Grindelwald to see both sides of the mountain trip.
