Descend the Ewigschneefeld easily in the direction of the peak. Don’t go below 3300m, aiming towards the L side of the main glacier, passing beneath the large spur that comes down from the summit of the Gross Fiescherhorn. Once beyond this angle up the side glacier that drops down from and head up to the Fieschersattel. You may join other tracks that have come directly from the Konkordia Hut. From the col turn L and ascend the mixed ridge to the Gross Fiescherhorn. This has one tricky part at the bottom, which you can rappel in descent. In the other direction the Hinter Fiescherhorn is mainly climbed on snow to the side of the ridge, with little difficulty. The views in all directions are very fine, especially from the Gross Fiescherhorn as it drops away very steeply to the N. Reverse your route of ascent or descend to the Finsteraarhorn Hut, as described above.
