This tough route takes in a remote Loch high on the Cairngorm Plateau, which is best enjoyed in winter conditions. The exit takes you up the east face of Cairn Gorm summit making it a worthy day out. The walk is possible as a day option during winter months, but an early start is required. Conditions down to Loch Avon (pronounced "ainne" in English) are challenging and will require winter skills using ice axe and crampons. You should also be fully aware how to use these as there is one awkward section on this descent. In summer the conditions are easier but this remains a tough excursion into the Cairngorm Mountains and you may encounter some harsh weather at all times of the year. Whatever the season make sure you are well equipped and know how to use it.

Start by parking the car in the Coire na Ciste Ski Centre (grid ref. NH990060) located 11 miles east of Aviemore. Leave the car park to the southeast following the vehicle access road to Shieling Station. Continue along for 300 metres and locate a path with steps to your right (grid ref. NH995050), which can be tricky to find in heavy snow. After 45 minutes the track meets a ski tow fence, this is a good place to gear up for the icy walk up the ridge of Fiacaill a' Choire Chais.

Leave the fence and follow up the obvious ridge keeping the rocks to your right. Stay close as the drop to your left increases and is often corniced near the summit. The summit of the ridge is marked by a huge cairn which can provide some welcome shelter. Remember the wind speed often varies between 50 and 80mph even on a normal winter's day.

Leave the cairn to the southeast. In clear conditions you will see a faint track following the Allt Coire Raiberirt River to the left as you slowly descend towards Loch Avon. The first sighting of Loch Avon is quite dramatic appearing far below and making a dramatic photo. Within 20 minutes the track starts to descend steeply with increasing exposure to your right. Around half way down there is a tricky section made worse by exposure to your right. This involves a large rock facing downhill towards the drop and is quite often iced over. Passing over this with good condition crampons is possible. However I chose to take a lower line with the drop behind me making a good hold with the axe in the snow and soil behind the rock. Remember to take great care on this section. After another 10 minutes or so another tricky section is reached. Not as bad as the first, the best option here is to simply stay on the path maintaining your centre of gravity close to the rock then stepping down backwards. After these two sections are cleared you can relax knowing the worst is now over as you stride down towards the loch.

Once the loch is reached locate the well defined path and turn right. You are now on the Loch Avon circular. The path stays close to the waters edge in general but does rise to cross some snow slopes in places, keeping the crampons on does help as you make your way to the intake where a small footbridge is found. Cross the bridge and continue round under the awesome slopes of Stacan Dubha until a ford is reached; cross here and continue along for about an hour until the eastern outlet is reached. Crossing here is helped in winter as there is less water but still take care crossing. After warm periods melting snow can cause increased river flows so if in doubt ask at the ranger station by the ski centre for advice before attempting this route.

The river successfully crossed, locate the path opposite and turn left. Within minutes the path rises steeply as you stride towards The Saddle (grid ref. NJ019034). Continue straight ahead following the water (or ice) picking up a path leading up the east face of Cairn Gorm. As the summit nears the path quite often disappears under solid ice but the going ahead is quite clear with the summit in sight. After a gruelling hour the summit is finally reached; if you are slightly off target then the worst situation you will find yourself in is a trail of clearly laid out cairns leading up to the summit. Once reached you can take in fine views all around, looking south you take in the scale of the Cairngorms, to the southwest Loch Morlich almost looks like a puddle with Aviemore just about visible beyond.

Leave the summit following the cairns and make your way back down to Ptarmigan Station. From here leave the station crossing the first ski tow and turn left keeping the tow to your right. Follow down for about half an hour and the path turns left again, well marked with cairns. Follow sharply downhill back to the ski centre and a phone box. Turn right back into the car park where you can either leave or enjoy a well earned drink in the walkers bar.

Please maintain social distancing - keep at least 2 metres away from other walkers. Travel restrictions for exercise in Wales and Scotland will be lifted in early July.
