Coll d'en Claret from Son Ferrandell

The Ma-10 crosses Coll d'en Claret at 499 m. Climbed from Son Ferrandell it is 2.1 km long and gains 104 m, an average of 4.9%.

It sits mid-table on all three measures: 104 m over 2.1 km, against an island median of 192 m. Most of the climbing on Mallorca looks like this. The steepest kilometre falls in the middle, from km 0.9, when the road is already 50 m above the foot. The other way up, from Esporles, is within 0.4 points of this side's average gradient, so the two are about equally hard. Pick the one that starts nearer to where you are staying. For a ready-made day, the Consell's signposted route Serra de Tramuntana - Sud comes over the top at km 53.3 of 130.3 km.

Kilometre by kilometre

The worst whole kilometre below runs from km 1.0, at 4.9%. No kilometre of it goes backwards — you climb 103 m and keep it.

The bends, counted

No bend on this climb is a hairpin, which here means a turn of at least 135° taken inside 150 m of road. The sharpest turn on it comes to 122°, an ordinary corner. 2 bends on the climb reach 90°.

That puts this road 85th of the 116 climbs with a hairpin count, at 0.0 hairpins per kilometre. The twistiest roads on Mallorca has the whole ranking, the rule the count uses, and four published counts checked against the road they were counted on.

How it compares with every other climb here

Its steepest kilometre averages 5.3% against an island median of 7.1%, so it is gentler than the typical climb here. It gains less than the 192 m of the median climb on the island. The table sets every other measure against the island median in the same way.

The gear it asks for

Whether you ride up a climb or walk it depends on its steepest sustained kilometre, which here is 5.3%, far more than on its average. The calculator below uses that figure and opens on this climb: change the chainring, the cassette and your weight and it tells you what cadence that gear turns.

Temperature at the top, and what the way down feels like

You start this one 395 m above the sea and finish it at 499 m. The climb itself adds too little height to change the air much, so the figures below describe the col you arrive at. In January, the coldest month at this top, the plain 8 m above the sea averages 14.4 °C around 12:00 while the summit averages 10.3 °C: 4.1 °C the climbing did not buy you. In July the same top sits at 27.4 °C.

Then you turn round. Going down at 30–50 km/h you make your own wind, and at 08:00 in January the air at this top — 6.1 °C standing still — feels like 1.5 °C at the slower speed and 0.2 °C at the faster one. By 12:00 the air at this top is too warm for the wind chill index to apply, in every month of the year, so a cold descent here is an early-morning problem. Whatever you would wear on the way up, the way down is the reason the gilet is in the pocket.

The temperatures are read by height between two thermometers 1,007 m apart, so a top on the north coast gets a figure measured elsewhere on the island. They are also open-sky readings: where the mountain shades the road, the morning will be colder than the table. What the temperatures do across the whole island, and what to put in the pocket, is on the kit guide.

How much traffic this road carries

All of this climb is on the Ma-10, all 2.1 km of it. The Consell de Mallorca counts 8,217 motor vehicles a day on that road. Across eight counting points its quietest reads 5,930 a day and its busiest 11,189, so that figure is the average for the whole road, and the stretch you climb may carry more or less.

Of the 16 roads the island's measured climbs run on, four carry more. It carries 14 of the climbs measured here, so that one figure is the traffic behind all of them. For the scale: the busiest of them, the Ma-15, counts 27,013 a day.

A daily average smooths a whole year, so a February Tuesday and an August Sunday are one number here; ride early and you are riding under it. It counts motor vehicles only, so there is no count of cyclists. What these figures do to the risk per kilometre driven, road by road, is on the road-safety guide.

On the signposted network

The Consell de Mallorca signposts sixteen cycle-touring routes across the island, and following one is the easiest way to fit this climb into a day. These are the ones that include it, the direction they ride it in, and how far into the route it comes:

The other side

There are two ways up to Coll d'en Claret, and they ride differently. Here they are side by side:

What else is close

What else is up here, if this one turns out to be short of a day. Distances are straight-line between the summits, not by road — in the Tramuntana the road between two tops four kilometres apart can be fifteen.

Or go back to the whole atlas, where you can filter and sort all 75 climbs at once.

How this was measured, and how to read it

• The list of climbs comes from a query against OpenStreetMap: every named pass on a paved road, and every named summit above 150 m where a paved road ends. Each entry carries the OSM id of its top and of the village it starts from.
• Ways tagged as closed to the public — private, no, customers, permit — are removed from the road network before anything is routed, so no climb here is measured up somebody’s drive. A road shut to cars but open to bicycles is kept.
• The road is the OpenStreetMap centreline of whichever road actually crosses the pass. It is not a GPS trace of one ride, so no rider’s wander or lost signal ends up in the number.
• Elevation is sampled every 10 m from the Spanish national 5 m terrain model, and interpolated in a straight line through tunnels and over bridges, where a terrain model reads the mountain above or the valley below.
• Where a road reaches a tunnel mouth without going through it, the model has already climbed the hill the road is about to pass under, so the last metres before the portal are left out. One climb on the island is affected, and its page says how far short of the portal its figures stop.
• The foot of the climb is the lowest point on that road between the summit and the named village. The distance from the village to the foot is reported separately, because on several of these climbs it is kilometres.
• Height gained is summit minus foot. A running total of every rise would depend entirely on the sampling interval, and that is the biggest single reason published figures disagree.
• Average gradient is height gained divided by length. The mean of the per-sample gradients would over-weight the flat stretches, so it is not used.
• The steepest kilometre is the largest height gain over any 1,000 m window on the climb, sliding 10 m at a time.

How we got this Inventory queried from OpenStreetMap; the road walked from Son Ferrandell to Coll d'en Claret on the filtered island road graph; elevation sampled every 10 m and smoothed over 50 m. Comarca from OpenStreetMap admin_level=7 boundaries by point-in-polygon.Computed from OpenStreetMap road centrelines (ODbL) and IGN Elevacion4258_5, Spain’s 5 m national terrain model (CC BY 4.0 scne.es).Computed 7 August 2026.

Sources, because these licences require the attribution: road geometry © OpenStreetMap contributors (ODbL); elevation from the Instituto Geográfico Nacional (CC BY 4.0 scne.es); comarca boundaries from OpenStreetMap admin_level=7. This climb clears the 100 m the atlas requires of an entry; the ones that do not are listed there with their figures.

Son Ferrandell is where this climb starts, so from there you are on it within a kilometre of the door. Somewhere to stay the night before. Otherwise it is a hire car from Palma, like most of the island.
