Using a Swiss travel pass I want to get from Interlaken Ost to Jungfraujoch.
Do I need to purchase another ticket for this journey, if so which one and do I need to reserve a ticket. We want to spend the day seeing Jungfraujoch and Grindlewald then returning to Interlaken in the evening.
Thank you for any advice.
