A Montseny beech-forest day: late autumn colour above the cloud

Waypoint 01

Why the beeches are there at all

The massif rises high enough and catches enough cloud that it holds forest types belonging to much colder latitudes. Below, you walk through cork oak and chestnut. Higher up the beech takes over completely, and above that the ground opens into heath and grass on the summit domes. Walking up through those bands in a single morning is the whole point of the day, and it is the reason we come back every year rather than treating it as a one-off.

Colour usually arrives late here compared with mountains further north. Our notes put the good window in the second half of October and the first two weeks of November, with a lot of year-to-year variation depending on how dry the summer was. After a hard drought the leaves go brown and drop rather than turning. We check recent photographs before committing, and we accept that a third of our attempts land on a fog day.

Getting there is the hard part

This is the walk where our train-first habit breaks down. There is a rail line along the valley to the towns at the foot of the massif, but from the stations to the actual trailheads you need either an infrequent local bus, a long road approach on foot, or a car. We usually share two cars between six or seven people and split the fuel, and we accept that the day starts earlier than any of us would like.

If you do go by train and bus, plan around the bus rather than the walk. The service is built for residents, not for walkers, and the return departure in the late afternoon is often the only one that works. That constraint sets the turnaround time before you have taken a single step, which in practice is not a bad way to plan a mountain day. Check the timetable the same week you travel, because the winter and summer services differ.

• Full day: six to seven hours moving, 900 to 1,100 m of ascent depending on start point
• Cloud often sits as a layer between roughly 900 and 1,300 m; above it the summits are clear
• Streams are frequent but drinkable water is not; carry what you need
• Mobile coverage is patchy in the valleys and fine on the tops

Walking up through the layers

The lower sections follow old paths between drystone terraces and stream beds, damp and mossy, with the light staying green even in November. Then the beech closes over and the floor turns to leaf litter deep enough to hide the trail edges, which is the one navigational annoyance of the day. Paths that are obvious in summer become a suggestion under twenty centimetres of leaves, so we slow down and check junctions properly.

Above the treeline the character changes again: wind, heath, wide views north towards the Pyrenees on a clear day, and much colder air than the valley suggested. People routinely underdress for this. We carry a warm layer and a windproof even when the town at the bottom was fifteen degrees and sunny, because the difference between the car park and the ridge can be ten degrees plus wind. Gloves live in the bag from October onwards and get used more often than anyone expects.

Turnaround, fog and the descent

Our rule on Montseny is a fixed turnaround time set from the last transport or the earliest sunset, whichever bites first, minus the descent estimate plus an hour. In November that usually means turning at around half past one regardless of how close the top looks. Nobody has ever regretted this. The descent through beech in fading light is slower than the map says because the footing is uneven and hidden.

Fog days are not wasted days. The beech wood in cloud, with water dripping off every branch and the visibility down to thirty metres, is genuinely better than the same wood in sun, provided you are not relying on views for navigation. What we do not do in fog is wander onto the open summit ground looking for a viewpoint. We stay in the trees, walk a shorter loop, and go down early.
