Bidean nam Bian route times by Naismith's rule

The times above use Naismith's rule: 5 km/h on the flat plus 10 minutes for every 100 m of ascent, rounded to the nearest 5 minutes. "There and back" doubles the distance and counts the ascent once, for coming down the same way. Naismith assumes a fit walker and no stops, so add time for breaks, a heavy pack, rough or snowy ground, and a group that moves at its slowest member's pace.

Before you pick a route

The grade describes the ground in fair weather. Wind, rain, cloud and ice change it: a Moderate path can be hard to follow in mist, and a scramble in strong gusts is a different proposition from the same rock on a calm day. Check whether it is safe to climb Bidean nam Bian today and the Bidean nam Bian 14-day forecast before you set off, and allow for the walk out in daylight.

Planning a day on Bidean nam Bian routes

The walking times above use Naismith's rule, which assumes a fit walker on good paths with short stops. Most groups take longer: add a quarter for a mixed group, more for children or heavy packs, and plan the descent as carefully as the climb, because tired legs and fading light cause more trouble on the way down than on the way up.

Start early. Car parks at popular starts fill by mid-morning in summer and at weekends, and an early start leaves spare daylight if the weather turns or the walk takes longer than planned. In winter, work back from sunset and leave a margin of at least an hour.

Carry a map and compass and know how to use them, even on a well-trodden path; a phone battery fails fastest in cold, wet weather. Pack a waterproof jacket and trousers, a warm layer, a hat and gloves in every season, plus food, water and a head torch. Tell someone your route and when you expect to be back.

If you are new to Bidean nam Bian, choose the easiest route in the table for a first ascent and save the harder lines for a settled day when you know the mountain. Turning back is always an option; the summit will still be there.
