Plans for a new visitor development at Glentress Forest near Peebles have been approved by Scottish Borders Council.
The plans hope to see visitor numbers rise to 500,000
The Forestry Commission's mountain biking and walking centre already attracts about 300,000 visitors a year.
It is hoped the new viewing centre with cafe, shops and changing facilities could take the figure to nearly 500,000.
The development should be completed in summer 2008 to act as a "gateway" to the Tweed Valley Forest Park.
