Hi, I am visiting the area in early April 2018 and of course plan on visiting Jungfraujoch. Can you do the sledging in April, I read somewhere it may not be available then as it’s low season. I’m praying it is! If it’s not available does anyone have any suggestions of where we may be able to see and sled in some snow in April? We will be in Switzerland from the 1-8 April.
