Take the A938 to Carrbridge then take first left almost as soon as you turn. You will need to turn round to get back onto the A9
Nice, fairly open, forest here to stretch your legs. At the back of the forest is the railway line where in 2010 more than 100 rail passengers were stranded for more than seven hours when their train hit a snowdrift - then a rescue train also became stuck.
The first train had became snowbound near Blackmount, between Carrbridge and Slochd, 20 miles south of Inverness. A second train was sent carrying food and blankets but it too got stuck.
A third train was then sent out which the 107 passengers had to walk to in the dark through snow and high winds.
A snow plough had cleared the track to enable the third train to reach the scene.
The passengers finally reached Inverness, a distance of about 25 miles, at about 0315 BST. The overall journey should have taken three hours 23 minutes but instead lasted more than 11 hours.
Hopefully your journey will not be hit with such delays but if you have some time to spare, instead of turning right back towards the A9 turn left and head south through the village of Carrbridge with its famous arched bridge (and of course more caches!). You can rejoin the A9 either before or after Aviemore.
You are looking for a small lock N lock box in a cammo bag.
Cache box has some swaps and room for small trackables or coins. Note the 'bean' pen is not a swap and stays with the cache.
