You need snow off course, which this winter has been in short supply, but too much snow and the roads are closed, too little snow and it defeats the objective.
If the snow is too deep it is very difficult to cross the moors plus I'm carrying my photographic equipment. Today I took both 500mm and 300mm although in the end I only used the 500mm.
Low cloud can also be a problem, during the winter visibility can be reduced to a few metres on the moor for days on end so you need to watch the weather forecast.
Finally, and it really goes without saying, you need the Mountain Hares.
As usual I went up to the Bleaklow area off the Snake Pass. Driving up I thought the snow had all but disappeared but once past the Snake Pass Inn there was plenty on the tops.
There were plenty of hare foot prints in the snow but it took quite a bit of walking before I located one that was prepared to sit still with me close-by.
Was it worth the effort...a definate yes!
