THE Overland Track is fully booked and day walks in the Cradle Valley are increasingly popular as walkers head to Tasmania's national parks and reserves.
A Parks and Wildlife Service spokeswoman said that 60 walkers were departing on the Overland Track each day until January 21, with limited spaces until January 25.
Cradle Valley staff estimate visitor numbers are slightly up on this time last year.
``Freycinet National Park received about 188,000 visitors last year. It is estimated that 140,000 of those visitors walk to the lookout to view Wineglass Bay,'' the spokeswoman said.
``During peak periods, up to 2000 people go to the lookout in one day and there can be up to 50 people on the structure and around the area at any one time.''
She said the Freycinet Peninsula Circuit, a 30-kilometre multi-day walk taking in Cooks and Bryans beaches and returning via Wineglass Bay, was maintaining its popularity despite a lack of water in the creeks along the track, meaning walkers needed to carry their own.
Parks and Wildlife Service Freycinet visitor centre co-ordinator David Adams said it seemed Freycinet was popular with visitors taking in the Falls Festival and MONA.
He said Freycinet was also a popular day trip destination with visitors based in Hobart and Launceston.
The Parks and Wildlife Service is receiving inquiries about which sections of the Three Capes Track can be accessed.
Staff at the Walls of Jerusalem National Park say up to 100 walkers have been departing each day over the Christmas and New Year periods for various destinations, which is similar to last year's numbers.
Boxing Day to Australia Day is the peak season for visitation and bushwalking in Tasmania's national parks and reserves.
