Serra de Tramuntana nord: the official 109 km loop with Sa Calobra in it

Of the sixteen cycling routes the Consell de Mallorca has signposted across the island, this is the one that contains Sa Calobra. It starts at the roundabout where the Ma-13 meets the Ma-2220 in Alcúdia, crosses the Serra to Lluc, drops 10.0 km to the sea at Sa Calobra because there is nowhere else that road goes, climbs back out, and comes home over the coll de sa Batalla and across the plain. The Consell publishes it as 109.4 km of prose. Here it is as a track.

Serra de Tramuntana nord — 110.5 km from Alcúdia, drawn from the reconstructed track

Where the climbing is

High point 722 m · lowest 1 m · marked: Coll de Femenia from Pollença (km 24.6), Coll dels Reis from Lluc (km 44.2), Coll dels Reis from Sa Calobra (km 64.2)

The shape of this ride is not the shape most people expect. There is no climb at all in the first ten kilometres — 47 m of ascent across the plain out of Alcúdia — and then almost half the day’s climbing arrives in two blocks that are twenty kilometres apart: the long drag up to the coll de Femenia, and then Sa Calobra, which you meet at km 54.2 — 49% of the way round, with 1,064 m of the day’s climbing already behind you.

Every ten kilometres: what you gain, what you give back, and how high it gets

Kilometres	Ascent	Descent	Highest point in the block
0 – 10	47 m	17 m	40 m
10 – 20	281 m	6 m	316 m
20 – 30	309 m	141 m	562 m
30 – 40	227 m	155 m	677 m
40 – 50	200 m	452 m	722 m
50 – 60	403 m	292 m	415 m
60 – 70	401 m	203 m	722 m
70 – 80	86 m	304 m	677 m
80 – 90	65 m	358 m	394 m
90 – 100	47 m	144 m	130 m
100 – 110	34 m	33 m	29 m
110 – 110.5	5 m	3 m	11 m

How we got this Elevation sampled every 20 m along the reconstructed centreline from the Instituto Geográfico Nacional's 5 m terrain model, then smoothed over 100 m before ascent is summed. The smoothing window is stated because without one the model's own vertical noise adds climbing the road does not have.Computed from OpenStreetMap (ODbL) and IGN Elevacion4258_5 (CC BY 4.0 scne.es).Computed 5 August 2026.

Ascent and descent come out at exactly 2,105 m each, which is what a loop should do and is a useful check that the reconstruction closes properly.

The climbs on it

These are matched by geometry, not by name: a climb counts only where the track passes both its foot and its summit and covers the right distance between them. 3 of the 6 you go down, which is a different day out and is marked as such.

Climbs this route contains, in the order it meets them

Climb	At km	Direction	Length	Height gained	Average	Steepest km
Coll de Femenia from Pollença	10.6	climbed	14.0 km	485 m	3.5%	7%
Coll de Femenia from Lluc	24.6	descended	5.7 km	62 m	1.1%	4.5%
Coll dels Reis from Lluc	30.4	climbed	13.8 km	248 m	1.8%	8.1%
sa Bretxa from Sa Calobra	51.6	descended	2.6 km	180 m	6.9%	7.7%
Coll dels Reis from Sa Calobra	54.2	climbed	10.0 km	708 m	7.1%	8.8%
Coll de sa Batalla from Caimari	75.6	descended	8.4 km	410 m	4.9%	6.4%

How we got this A climb is collected when the track passes within 120 m of both its foot and its summit and the distance ridden between those two points is within 30% of that climb’s own measured length. Foot before summit means the route climbs it; the other order means it descends it, which is a different day and is labelled as one. Nothing is matched by name.Computed from the 121 climb-sides this project has measured.Computed 5 August 2026.

What Sa Calobra does to this route

You reach the top of the Ma-2141 at km 44.2, the highest point of the day at 722 m, and then descend 10.0 km to the sea — where the road ends. The only way back is the same 10.0 km, at 7.1% average with a steepest kilometre of 8.8%, starting at km 54.2 of a 110.5 km day on legs that have already climbed 1,064 m by km 50. Once you are back at the top the climbing is over: the blocks after the summit hold 237 m between them, across the last 40.5 km. That ordering is the argument for riding the loop in the direction the signs take it, and for eating before the descent rather than after it — at the bottom there is one road out and it is the climb.

The measured detail of that climb — every kilometre, the gradient bands, and why our summit altitude disagrees with every published figure — is on its own page.

The roads it uses

Where the reconstruction spent its kilometres

Road	Distance on it
Ma-10	37.0 km
Ma-2141	25.3 km
Ma-13	9.3 km
Ma-2130	8.5 km
Ma-2202	5.9 km
Ma-2131	5.3 km
Ma-13A	3.6 km
Ma-2220	3.3 km

How we got this 85.6% of this route ran on roads the Consell names for it. The rest is the connecting streets through Alcúdia, Pollença, Caimari and Campanet, plus the lanes the source describes by name rather than by number.Computed from OpenStreetMap way tags (ODbL).Computed 5 August 2026.

The Ma-10 carries 37.0 km of it and the Ma-2141 — the Sa Calobra road, ridden in both directions — 25.3 km. Between them that is over half the route on two roads.

How much of this you should trust

A reconstruction is published as a track only if its measured distance lands within 5% of the distance the Consell publishes.

This route is accepted: our 110.5 km against the Consell’s 109.4 km is a +1% difference, one of the closest agreements of the sixteen. That is a real check but not a complete one — it says the reconstruction is the right length, and combined with 85.6% of it running on the roads the Consell names, that it is very probably the right line. It does not prove that every junction matches the signs. If you ride it and find the signs going somewhere else, that is worth knowing and we will correct it.

Where to start it from

The route as signposted begins in Alcúdia, and the first 10.6 km run out across the plain before the road starts climbing towards the coll de Femenia — so a base anywhere in that corner of the bay puts you on the loop without a transfer. Staying in Palma instead means riding the width of the island before the route even begins, in both directions.

For the parts of that we can actually help with, both links are marked and pay us if you use them: somewhere to stay in Alcúdia or Port de Pollença, and a hire car from Palma airport, which is the only sensible way to arrive with a bike box. We have no bike-hire relationship on this island yet and are not going to invent one.
