Mallorca's cycling regions: the mountains hold a fifth of their road hostage, and how steep a region is barely predicts whether you can loop on it

You have a week, you have looked at the map, and the map has already decided for you: the mountains are in the north-west and everything else is the bit in the middle. Every guide to this island cuts it that way, including the ones quoted further down, and they are not wrong. They are answering one question — how steep is it — and then stopping, because the second question needs a road network read as a shape rather than as a list of climbs, and nobody has read it.

So here is the answer first. Ride the Serra de Tramuntana for the mountains, and know what they cost: 21.2% of its riding road has no alternative of any kind — the highest share on Mallorca — so a fifth of every week spent there is road you ride twice. If you want a different loop every day rather than a different climb, ride from the Llevant or the Pla de Mallorca — level at 14.7% and 14.9%, and nothing in this measurement separates them. And the emptiest riding on this island is in Migjorn, where 74.0% of the road carries no number at all — the one part of Mallorca this survey’s ten publishers mention exactly once between them.

The two orders, and why they are two

The island’s roads were contracted to 13,868 runs between 10,102 junctions, and each run was asked one question: if this road were shut, is there another way? Across the whole ridable network, 24.1% of it has no answer — 1,224.5 km of road you can only leave the way you came in.

How we got this A run of road counts as committed when removing it disconnects the network — no alternative at any length of detour. Each one is then re-checked against the full mapped network including residential streets, and only those that are cut edges there too are called confirmed.Computed from 5,082.1 km of ridable road contracted to 13,868 runs between 10,102 junctions.Computed 14 August 2026.

Read the third and fourth columns against each other and the expected relationship is not there. Palma offers a turning more often than anywhere on Mallorca — 29.7 junctions every ten kilometres — and has the least committed road of the six. That much is a city doing what cities do. But Pla de Mallorca offers the fewest turnings on the island at 12.6, and is 4th of 6 for committed road — which is the opposite of what a sparse network is supposed to look like. Over the six the two orders run against each other at τ = -0.33.

The two columns are asking different things and the difference is the whole point. Junction density is how often the road offers you a decision. Committed share is whether the decision goes anywhere. The Pla gives you fewer choices and nearly all of them are real; the Serra gives you more and a fifth of them end at a chapel, a port or a dam.

And quietness predicts neither. Across the six, the share of road carrying no number and the share with no way round correlate at τ = 0.07 — which is to say not at all.

The roads Mallorca cannot route around

8 of the 25 corridors this measurement names have no alternative anywhere on the map — not a lane, not a village street, nothing. The rest have a way round and it runs through somebody’s street, which is a weaker and more useful thing to know, so the two are kept apart rather than added together.

Ma-2210 is the one a rider actually meets. 16.6 km of road hangs off 3,282 m of it, and there is no second way onto any of it: the Formentor peninsula is reached by one road or it is not reached. That is not a hazard and it is not a complaint — it is the reason a Formentor morning is planned as an out-and-back by everybody who has ever ridden it, stated as a property of the network rather than as a habit.

The largest corridor in the whole list, Ma-2200 with 24.1 km behind it, is not confirmed — a way round exists, and it is ordinary streets rather than a second through-road. The record does not say whose streets: it knows the detour is there and not where it goes, and the nearest measured town to the middle of the road is Port de Pollença, 0.6 km off in a straight line. That is exactly the distinction the check exists to make, and a page that skipped it would have published the island’s most dramatic dead end and been wrong about it.

The longest you can ride here without choosing anything

Every other comarca’s longest junction-free run lands between 7.8 km and 8.2 km, which is a remarkably narrow band for six quite different places — and then the Serra doubles it.

What each part of the island gives you, per hundred kilometres

Counts favour whichever region has the most road. These do not.

Every name in that first column is a page: the six compared, and behind each one the comarca’s full climb list, its base towns, the roads it holds that the island cannot route around, and its boundary drawn against the rest of Mallorca.

Three things in that table are worth stopping on.

The Serra has the least road per square kilometre on the island — 0.83 km per km² against 2.55 around Palma and 1.76 in the Pla. The region everybody comes to ride is the region with the fewest roads to ride, which is most of why the same climbs appear in every account of it.

The Serra also carries more dirt than tarmac by a factor of 2.32 — 1,604.4 km of mapped track against 690.2 km of riding road. The gravel guide measures that network properly, with a stricter rule about what is ridable; the point here is only that the island’s dirt is not where the flat is.

And the Pla is the thirstiest part of Mallorca. 0.3 public taps per hundred kilometres of riding road, against 12.0 in the mountains — the region the market sends beginners and families to has, per kilometre of road, about a fortieth of the mountains’ water. That is the single most useful thing on this page and it is the one number nobody would guess.

Know before you ride

• A week in the Serra is a week of out-and-backs, by construction. 21.2% of its riding road has no alternative. Plan the day around the descent you want, not around a loop you are hoping exists.
• Carry more water in the flat than in the mountains. The water guide measures the gaps over the road you actually ride; this page only says which part of the island the gaps are in, and it is not the part anybody expects. In the Pla, 0.3 taps per hundred kilometres means planning refills around villages rather than around fountains.
• Migjorn has 0 cycling cafés in this site’s survey and the highest share of unnumbered road on the island. Those two facts belong in the same sentence: the emptiest riding here is empty of everything. See the café guide for what the corpus does name.
• The signed routes are not the island. 1,732 km of official cycle route exists against 5,082.1 km of ridable road, so following the signs is riding about a third of Mallorca.
• Two of the biggest dead ends on the map are not dead ends. Where this page says “no way round” it means the check confirmed it against the full street network; where a corridor has a street alternative it is listed separately and named as such.

What the market says, tested

19 claims from 10 publishers in 3 languages, each proved word for word against the page it comes from on 25 August 2026. 16 hold and 3 differ — and 7 of them are answered by a proxy rather than settled, which is marked on every row because the difference matters more than the verdict.

The one that matters most is the one that differs. mallorca.com’s three-way cut of the island — the hilly Serra de Llevant, the Tramuntana mountains, the flat interior — is a good description of terrain and it does not predict the road. Migjorn, which appears in nobody’s mountain list, is 2nd of 6 for committed road, ahead of the hilly Llevant. Sorting Mallorca by how steep it is tells you very little about whether you can ride a loop on it.

And the island’s own authority does not use the comarques either. The Consell de Mallorca’s cycle-route plan runs on its own lettered zones — C for Ponent, M for Llevant, P for the Pla and Migjorn, and a Tramuntana split three ways into north, central and south. That is a rider’s geography drawn by the body that maintains the roads, and it splits the mountains where the administrative boundary does not.

The claims about quiet, which nothing here can settle

Read together they say something the individual pages do not. 3 separate publishers, in 2 languages, recommend the Pla for its quiet lanes — and the Pla is 4th of 6 on the measurement, behind Migjorn at 74.0%. The market is right that the middle of the island is lanes. It has simply never compared it with the south.

How to read these numbers

How we got this The classes a bicycle rides between places, with residential and living streets left out because a resort's cul-de-sac grid is not riding. 96.3% of it stays in one connected piece after that cut, which is the test of the cut rather than an assumption about it.Computed from trunk|primary|secondary|tertiary|unclassified|cycleway.Computed 14 August 2026.

How we got this The line between "the mountains" and "the flat bit" is somebody else's, so the classification is checkable rather than editorial. A run of road belongs to the comarca its midpoint is in.Computed from OpenStreetMap boundary relations at admin_level=7, each with its own Wikidata id.Computed 14 August 2026.

How we got this a statement about one measured region, or about the island, made by a publisher in the survey and proved word for word against that publisher’s own page on the date recorded beside itComputed from a page making at least one claim about a part of Mallorca rather than about the island as a whole or about one road, naming that part so it resolves to a comarca, readable without an account, a paywall or a CAPTCHA.Computed 25 August 2026.

How we got this A junction is a mapped node where three or more road segments meet. Both the count and the road it is divided by are attributed point by point, so neither depends on where a comarca boundary cuts a road.Computed from 8,360 junctions and 1,742 dead ends island-wide.Computed 14 August 2026.

The riding network leaves out residential and living streets, because a resort’s cul-de-sac grid would otherwise read as committed mountain road — Palma’s comarca is more than half street by mapped kilometre, and the Serra’s is nearly half. That cut is tested rather than assumed: 96.3% of the riding network stays in one connected piece after it, and every corridor called “no way round” is re-checked against the full street network before it may be described that way.

What the measurement does not see: traffic, surface, gradient on the lanes, road width, or anything about a road that is not its position. 68,638 registered bed places carry no coordinate in the island’s accommodation register and are therefore in no region’s total above — a gap the hotels guide describes in full.

One page named in the survey is listed rather than dropped, and is worth reading at the source — so what this corpus leaves out can be checked as easily as what it holds.

Where to stay in each of them

The base-town decision is a page of its own — the first-trip base guide ranks the towns on reach, climbing and services rather than on the comarca they stand in, which is the right axis for a first week. What this page adds is the shape of the network around each one: a base in the Serra buys climbs and out-and-backs, a base in the Pla buys loops and no water.

In the mountains that means Sóller or Pollença; in the Pla, Sineu, which is the town Inntravel builds three of its circular days around; and in the emptiest corner, Santanyí or Campos.
