Take the road to Isola 2000, and about 4–5 km past the village of Isola, you’ll come across marker 60 on your left. You can park on the hard shoulder on the right a few metres further up.
(S/E) Continue along the road heading due west for about 50 m. Turn right onto a track that climbs up the Guercha valley, towards the Lausfer lakes. Pass under the power line and continue along the winding track.
(1) Cross the Guercha torrent and carry on along a gentle, pleasant ascent with little change in elevation.
(2) You’ll pass a few houses set against a magnificent backdrop: numerous streams and waterfalls dot the ascent. Continue to the end of the track at marker 61. Keep heading north towards the lakes. Be careful to stay on the path, otherwise you’ll end up in a field of stinging nettles. From here onwards, the markings are often few and far between and not easy to spot. Keep your eyes peeled.
(3) You’ll need to cross the stream here, but the snowmelt makes it impassable if you want to stay dry. The yellow markings are clearly visible on either side of the stream, so the path is definitely there. Take off your shoes and wade across – that’s still the easiest option. I couldn’t find a safe, dry place to cross.
Continue to follow this stream.
(4) From here, the gradient steepens and the terrain is quite rugged. Take care as you make your way over the scree; good footwear and walking poles are essential, particularly for the descent. The yellow markings are still not easy to spot, but you’ll eventually find them.
(5) The IGN map shows a fork here, but I didn’t see anything. Stay on the right path by following the markings. The pass isn’t far now!
(6) Here, at last, are the first two Lausfer Lakes. The path runs between them.
(7) The path isn’t very visible here, but it’s nothing you can’t manage. You can climb up to the upper lake via the left or the right – it doesn’t really matter. Go round it to the west, passing a bunker, to reach the path leading to the pass. Be careful – there’s still a bit of snow here in May.
(8) You’ve now reached the Col du Lausfer, marked by marker 65 and a boundary stone. Italy is directly opposite, and you’ll see a path heading north towards the summit. It isn’t very far, and although it looks daunting from the pass, the path is perfectly passable. You’ll only need to use your hands once or twice, but it’s nothing too difficult. Stay on the path and keep an eye out for cairns in the scree sections. You’ll reach the summit very quickly.
(9) You’ve now reached the summit; enjoy the magnificent view before heading back down the same way to (S/E).
You can also take a short detour to Upper Lausfer Lake from the Col de Lausfer.
