Pilatus rope park & summer toboggan run. A very particular attraction on Mount Piatus is the longest summer-toboggan run of Switzerland - a funny and sportive experience one should not miss. The adventurous, racy run down the 1350-metre long chrome-steel channel â the longest summer toboggan run in Switzerland â starts on FrÃ¤kmÃ¼ntegg (1415 m). The numerous twists, turns and dragons' dens (tunnels), promise fast fun from May to October with each run a memorable and exciting experience.
You are here. The Longest Day of the Year. The summer solstice! On the summer solstice, birds nesting near Juneau, Alaska take advantage of almost 18 1/2 hours between sunrise and sunset. This day in south Texas is considerably shorter, so the Altamira Oriole has only 14 hours to sing. Seattle's Song Sparrows see 16 hours of daylight; Sacramento's only 15. Birds nesting north of the Arctic Circle have six weeks with almost 24 hours of daylight every day.
