Just been up there this weekend.
Word is a lot of the singletrack on the east side of the Feshie is gone as well as there's been a lot of erosion from the floods. We didn't go down that side of the river, stuck to the west side, so don't know exactly where (could be the bits between Achlean and the bridge, or possibly further upriver, the section you use coming over the Geldie from White Bridge as it is pretty close to the river).
Apart from a lot of debris you wouldn't know it had been horrendous a fortnight ago – buff as you likes today!
