Carn an Fhidhleir & An Scarsoch, map 43; 14th August 2005, 6th June 2009 & 28th March 2019

Route 14/8/05 without Corbett: Cycle: 15.6 miles, Walking: 10.7 miles, Ascent: 1065m = 3500', Time: 7 hrs.
Route 6/6/09 with Corbett: Cycle: 15.6 miles, Walking: ~17.55 miles, Ascent: 1445m = 4750', Time: 10 hrs.

Warning: There are two major fords to be aware of: over the Allt Dhaidh Mor and over the Geldie Burn. After heavy rain they can become impassable very suddenly, the latter becoming over a metre depth of swift flowing water for much of its substantial width. If the Dee is high at the Linn of Dee, the Geldie Burn is unlikely to be fordable as it subsides only slowly after rainfall. Note particularly that the Geldie can rise substantially in the time it takes to do the hill part of the walk. If necessary, a 4 to 5 mile diversion west to the watershed at NN91648735 could solve any problems with the Geldie Burn, with another detour north for crossing the Allt Dhaidh Mor. Either diversion might lead to one becoming benighted. If full streams are liable to be an issue, leave any bike before fording the Allt Dhaidh Mor.
Access: Bike used & very helpful.
Route: There is an optional inclusion of the uninspiring Corbett Beinn Bhreac which adds around 7 miles and 350m to 380m of ascent to the walk, depending on what tops are traversed en route to and from the Corbett. Including this hill saves a day and a laborious cycle in to Bruar Lodge when ticking off Corbetts.
The distances & times quoted assume cycling between Linn of Dee car park and the Geldie Burn ford by Geldie Lodge.
The route is easy walking for the most part on the Munros, but tiresome heather moorland (with grouse & hares) & peat hags for the Corbett. For the descent from An Sgarsoch it is best to aim for, then follow, the green grass beside Allt Coire an t-Seilich down to Geldie Lodge. This avoids most of the peat bogs/hags as well as saving a little bit of distance.
The path is rather poor, even non-existent in places, for the route over Carn an Fhidhleir from the end of the made-up path north of An Sgasoch (as shown on the map) to the bealach with An Sgasoch. With poor visibility or when there is ground snow you should expect to lose the path. Note particularly that the ascent of Carn an Fhidhleir may well involve climbing a cornice to reach the summit ridge, and there are likely to be snow fields on the steep descent to the bealach.
If the Geldie Burn is too full to cross on the outward journey, continue path on N side of the "Burn" to near the watershed. Obviously, reverse the process of heading to the watershed on the return if necessary. It is probably better to leave bike on the N side of the Geldie partly in case the river rises, but also as there is a steep 300' (100m) ascent immediately on the south side, and the constructed path then goes up and down with unfriendly burn crossings.
Recommendation: Use plastic bags tied over your boots or take wind surfing shoes with you to avoid having wet feet all day after crossing the Geldie.
Mobile: No Orange signal at Linn of Dee nor on either Munro but Orange reception on the Corbett.
Weather 14/8/05: Dull and cloudy in AM; brighter & sunny PM. 6/6/09: Tops clear of cloud, but little sunshine & cold E wind.
