A snow machine was also on hand to complete the festive magic.
The free event - from 12 noon to 3pm - was organised by The Friends of Webster Park, supported by Knowsley Council and funded by the Big Lottery Community Spaces Fund.
One of the highlights of the day was a cheque presentation by Merseyside Fire and Rescue Service, who raised £1,200 to support the activities of The Friends of Webster Park.
Cllr Eddie Connor, Knowsley's Cabinet Member for Leisure, Community and Culture said: "The Winter Wonderland event was an outstanding success - and brought some early festive magic to many local families.
This event is just one of a number of great activities organised by our Green Space Ranger Service - in partnership with 'friends of' parks groups - which encourage local communities to enjoy their local green spaces."
