I am an Indian citizen from Chennai, India. I am 68 years young and am travelling to Switzerland with my wife, 67 years young. Our travel is scheduled between the 17th and 20th of August, 2019.
Please let me know what would be the average temperature during this period, and generally speaking, what types of clothes we should take with us, particularly for an excursion to Jungfraujoch and Mt. Titlis.
Would we be able to rent boots and warm jackets for the day at Jungfraujoch to safeguard us from ice and snow?
Would we need to carry any medicine to prevent from high altitude sickness?
