A long-distance event

Thursday 31st July 2025

Part of the extensive Forest of Birse, Balfour Forest shares some of the characteristics of nearby Glen Tanar, separated by the steeper and more complex terrain of Birsemore Hill.

Balfour was first used for orienteering during Royal Deeside 2017 and since then has only been used for a Regional Event in 2021 and a Scottish Orienteering League event in April 2024.

Balfour comprises a large area of mature coniferous plantation on the southern flank of the Dee Valley. There are four distinct hills with areas of complex glacial contour features between them. Open areas are interspersed with forest and both have localised rock features. Some areas of windblown and thinning have occurred since 2017.

Balfour is used with the kind permission of Birse Community Trust, Ballogie Estate, Dunecht Estate and a private landowner. The four areas of forest are managed differently contributing to a great variety of orienteering terrain.

For the elite classes only, this will be a Middle Distance World Ranking Event. For all other classes it will be a Long Distance event.

Directions
There are 2 car parks, A (west) and B (east). Campervans over 5m, EVs and any car with a passenger aged 70 and over or aged 11 and under should use car park A which is approximately 300m before the arena. Priority parking for helpers and those with special needs will be in the arena. All other cars should use car park B which is approximately 1.8 km from the arena. Competitors can go directly to the start from Car Park B but must report to download even if they do not finsih therir course.
The bridge over the River Dee at Aboyne is closed.
If approaching from the west (e.g. Ballater, Braemar) leave the A93 Deeside Rd at Dinnet, turn right across the bridge and then continue east along the B976. Shortly after passing the closed bridge turn right for 2 miles (3km) for car park A or continue straight on for a further 3 miles (4km) before turning sharp right for car park B.
If approaching from the east cross the river Dee at Potarch (unless you are already south of the river). Then travel west on the B993 for 2.5 miles (4km) and turn right onto the B976 for a further 0.5 mile (1km). Turn left and follow signs for car park B or continue for a further 3 miles (4km) before turning left to follow signs for car park A.
If you are coming from Aboyne by car you should initially travel west on A93 for car park A, crossing the Dee at Dinnet then following instructions as above. From Aboyne to car park B travel east on A93 to Potarch and then follow instructions above.
If cycling from Aboyne cross the Dee and turn left for 300m then follow signs to car park A and continue past there to the arena. We DO NOT recommend walking along this road as it is very narrow and will have a lot of orienteering traffic.
Competitors will not be allowed to arrive after 12:30 or leave before 13:00.

Terrain
Largely runnable, varied, plantation forest with some rough open ground. Several complex contoured areas. Parts of the plantation forest have been recently thinned, with much evidence of the workings being visible. There are many unmapped extraction lanes. There may be deep heather and bracken on some courses. Recent storm damaged windblown trees have been mapped with an orientated dark green uncrossable symbol.
Finishes
The Finish is in the arena.
String and off-string courses

Safety
Forestry operations have been taking place recently. Any machinery, log piles or other articles of work must be avoided. The forest is used by mountain bikers and their trails will be crossed by most courses. Occasional mountain bikers may be encountered on the day. Please give them a wide berth. A dry stone wall approaching the finish is only crossable at marked crossing points.
Junior courses
Courses 22 and 23 follow distinct paths, tracks, walls and rides with some taping between controls. There is also a taped section on course 21.
BOF Registration No.: 84584
Special Information
Day 4 is a World Ranking Event for elite classes who will run a middle distance course. View IOF Bulletin 2.
Because of the distance from Car Park B to the arena please give club tents to someone who is allowed to park in Car Park A. If this isn’t possible please contact the organisers for permission to park in Car Park A.
