We are two adults who will be in Pontresina in mid July primarily to hike and sightsee. We will drop off our rental car in Geneva and plan to travel by rail to Zermatt for 5 days, then Pontresina for 5 days. We are renting a home in Pontresina, no transportation passes are provided. What pass options might work best for travel during our time in Pontresina and Zermatt? We are thinking of buying a Rail pass for three separate days for the trips from Geneva to Zermatt, Zermatt to Pontresina and Pontresina to Geneva.
Thank you in advance,
