Bidean nam Bian


Quick Facts
This is the height of the mountain above sea level. However, on the climb, it is the ascent that matters, i.e. the sum of all the uphill parts of the route.
1150 m (3772 ft)

This is the standard notation used on Ordnance Survey Landranger maps.

Each reference consists of two letters identifying a 100,000 metre square block then three digits defining the Easting and finally the three digits defining the Northing with reference to the South West corner of the block.

NN166712 is the grid reference for the summit of Ben Nevis. Where you are given the map number ( For Ben Nevis = 41) it is acceptable to omit the two initial letters e.g. 166712. (Instructions on how to read the references are given on the OS maps).

Pinnacle of the hills

The UK is covered by 204 Ordnance Survey Landranger 1:50,000 scale maps. Maps numbered 1 to 86 cover Scotland but for the highest mountains (Munros) only 23 maps are required. The name given roughly describes the area covered by the map.

A description of the characteristics of the mountain including any hazards of which you should be aware.

Bidean nam Bian and Stob Coire Sgreamach are two peaks about 1km apart on a ridge running NW to SE from Glen Coe to Glen Etive. Collectively they have three ridges, running NE, the steep rocky ends of which are the Three Sisters which dominate Glen Coe.

Bidean nam Bian is the larger and more complex mountain. To the SE a steep ridge links to Stob Coire Sgreamach. To the NE a ridge leads to Stob Coire nan Lochan beyond which it splits to give two NE ridges, Aonach Dubh and Gearr Aonach, between which lies Coire nan Lochan.

The path into Coire nan Lochan facilitates an ascent of the grassy NW slopes of Gearr Aonach leading to the rocky E slopes of Stop Coire nan Lochan.

A further long ridge runs W turning NW to Stob Coire nam Beithe and on to An t-Sron to enclose Coire nam Beith. A well maintained path leads into this corrie from Glen Coe and once in the corrie, ascents can be made to the col between Stob Coire nan Lochan and Bidean nam Bian or the col between Stob Coire nam Beith and An t-Sron.

Hazards you may encounter on Bidean nam Bian include

2nd time round..still hard work but worth it..came out thru the lost valley this time, very steep descent initially over loose scree but settled down once nearer the valley, had to scramble over the boulders and cross the river in the dark..great fun.

Circuit over both Munros via lost valley and Coire nan Lochan on excellent made paths for majority of way.

Started to feel the chill of winter as I climbed ascending via Coire Nan Lochan. Louie (my dog) and I enjoyed the solitude that this route offered. Visibility was good untill the summit with the occasional shower.

The best mountain yet. Great scramble up to Lochan then an easy traverse up the ridge to Bidean. The massive buttress after Lochan is magnificent, seeing that is worth the climb alone. We continued (myself and my mate Marty) to summit Sgreamhach, an easy scramble at this time of year. Definately coming back in the winter as both mountains look more impressive and challenging at this time of year. Fantastic views over the Lost Valley. The descent can be tricky at all times of year, steep and hazardous. In winter it fills with snow and I can imagine avalanche conditions being prevelant.

The Bidean massif is a truely magnificent mountain. I love this hill. Climbed it with my mate Iain may 04 on a beautiful sunny day. Beware though, it demands respect. Steep sides with big drops coupled with loose scree paths make this a serious days climbing. It's all worth it though. The views from the tops are incredible, especially of the Aonach Eagach ridge. The route through Coire Gabhail and the Lost Valley is the busiest route up the mountain, it's also the best in my opinion. When on the top take the time to ascend Stob Coire Nan Lochan. A viewpoint to beat all others.
