Hi, I'm considering booking this tour with Norway's Best Flåm Railway, Flåm Zipline, Rallarvegen Cycling Tour | Norways best. We will be on HAL NS in August arriving in Flam at 10am. Available train departures are 10:45am or 12pm, with 55min ride to get to the station close to the zipline. I'm concerned that since it's not a ship excursion, we may not make the 10:45am train, so feel we need to plan for the 12pm train. I'm hopeful the logistics of the zipline doesn't take more than 1-1.5hr, which leaves about 3 hours for the 15km bike ride. We want to be latest back to the port by 5:30pm as ship leaves at 6pm. Does this sound doable? Has anyone done this excursion and can comment, traveling is myself & hubby (both 50s) and our 11yr old.
