We would like to get off the cable car from Birg on the way back from Schithorn and hike the Birg -> Bryndli -> Gimmelwald. This is hike route in Rick Steve's book. How difficult of this hike? How long does it take?
Sorry that I don't have the exact answer. I invite your attention to a map:map.search.ch/?pos=634316,156584&z=64
Perhaps Rick Steves gave information to support his recommendation?
