The six sites are Coronation Plantation, Nabb's Quarry Wood, Newhaven Plantation, Shay Bends Wood, Slack Hall Wood and Wetton Wood. The authority said it is planning to put six more up for sale later in the year.
Peak District National Park Authority assistant director Jane Chapman said: "Following a review of our properties, we have identified six woodlands to be sold now, with a similar number to follow later in the year.
"Having established or improved these woods – often by reclaiming former rubbish tips or quarry sites - then protected and maintained them over many years, we have fulfilled our primary objective as a national park. We now want to return these natural assets to the community, as we are reducing our liabilities at a time of budget reductions and would like to make the best possible use of the resources we have.
"The sales will allow us to focus on the protection, improvement and maintenance of our remaining woodlands.''
The Authority currently manages 120 woodlands, covering approximately 443 hectares of land. The portfolio has been acquired since the designation of the national park, with the aim of securing important landscape features, rescuing woodlands which were deemed to be under threat or in need of restoration. They were also acquired as part of major estates.
The first six woodlands to be sold are: Coronation Plantation, Leadmill, nr Hathersage (1.14 hectares), Nabb's Quarry Wood, Wildboarclough area of SW Peaks ( 0.44ha), Newhaven Plantation, Newhaven on A515 (1.8ha), Shay Bends Wood, on A623 Baslow to Calver road (0.8ha), Slack Hall Wood, nr Chapel-en-le-Frith on road to Winnats Pass (3.1ha), and Wetton Wood, above village of Wetton, North Staffs (0.16ha).
