Bidean nam Bian & Stob Coire Sgreamhach, Map 384; 10th June 2007

Route: 1530m = 5020' ascent; 8.0 miles; 7.25 hrs.


Route: This route is really only for those wishing to conquer the Munro tops. It includes Beinn Fhada (NN16435431) which has very steep sides and a tricky wall between it and Stob Coire Sgreamhach. Because of these problems, I would always do this route in a clockwise direction. For those skipping Beinn Fhada, the "tourist" route for Stob Coire Sgreamhach continues up the lost valley to the col west of the summit at NN15085370 rather than making a diversion left up the slope to Beinn Fhada.
The first point to watch in this route is that the path up to the Lost Valley crosses the river by a large boulder. I missed the crossing once and it led to some difficulties. Next, the steep climb up from the Lost Valley has many very minor rocks and crag bands to weave around. As they can be seen and negotiated more easily on ascent than descent, a clockwise direction works well. Once beyond the two tops of Beinn Fhada there is the aforementioned wall, the "bad step". A photo of it is given by Andy Wallace. I have avoided scrambling up this by taking a rather exposed gully to its left, i.e. on its south side. According to Alex Roddie, the easiest way up starts with a "ramp of slow slants left" which is probably what I took. Another reference for the route is in www.scottishhills.com. Finally, "Mike216" describes the route past the bad step as follows: "it was a breeze to find the route up, starting on the left (south-west) side a narrow ledge passes under the initial crags before doubling back and onto the crest of the ridge".
The next choice is an optional detour from the summit of Bidean nam Bian to include its northern Munro Top. Then various descents are possible from Stob Coire nan Lochan. One can take the north ridge down to 880m before turning ESE into the Coire nan Lochan valley as in the GPS route link above. In the table below the choice is to return SW to the col with Bidean and descend SE to the Lost Valley. This is about 0.6 miles longer, but involves marginally less ascent from crossing the River Coe back to the helipad parking.
Weather: Hot dry day, overcast, 18°C at start, cloud at ~1150m, very light wind.
