Restrictions have remained in place around the Glenmore area since July 15.
An emergency wildfire cordon around a village in the Cairngorms could be lifted on Friday, Scottish Fire and Rescue Service has said.
Road and access restrictions have been in place around the Glenmore area as firefighters tackled the wildfire in the Cairngorms National Park.
Scottish Fire and Rescue Service (SFRS) was first notified about a fire near the Ryvoan Bothy, close to Aviemore, around midday on July 15.
So far more than 500 firefighters have been deployed to fight the blaze, which has devastated an estimated 25 square kilometres of land since it started.
SFRS said on Wednesday night that it still had four fire appliances on site, with around 20 firefighters working alongside partners and helicopter support.
Thermal imaging drones are being flown twice a day to identify hot spots in the Glenmore area affected by the Cairngorms wildfire.
This work will continue in areas of difficult terrain for the foreseeable future as work continues to dampen down deep-seated fires.
SFRS said planning is under way to potentially reopen the Glenmore area on Friday, subject to the continued firefighting efforts.
The service emphasised that any adjustments to the cordon are subject to change depending on the conditions on the ground, and any reopening is only possible once all multi-agency responders agree.
Highland Council has been engaging with affected businesses in the Glenmore area about the potential to reopen.
When the area has reopened, SFRS said there will be further information and clear guidance on which areas are accessible.
Forestry and Land Scotland and Cairngorms National Park are in the process of implementing a public access management plan for forest paths, biking trails and roads, which will include signage and fencing.
