Two bottles or three — where Mallorca lets you fill them

Take three, and stop pretending the third one is optional

Two bottles is the number every guide to this island prints, and on the ride most people actually do — out along the Ma-10, over something, back — it is the wrong number for a reason nobody writes down: Mallorca’s water is not on the road. It is in the villages, behind counters, at hours somebody else decides.

Measured over the island’s own eight official cycling routes, the longest stretch with no public tap within 500 m of the road runs from 35.9 km to 81.8 km. Count the bars, the cafés, the filling stations and the village shops as well — everything that can fill a bottle when it is open — and the worst gap on any of the eight falls to 21.5 km.

Those two numbers are the whole guide. The first is the ride you get on a February Monday at eight in the morning. The second is the ride you get in May at eleven. Carry for the first one and the second is a bonus; carry for the second and the first is a walk.

The eight official routes, wet and dry

The Consell de Mallorca publishes 8 cycle-touring routes this site has reconstructed and accepted. Here is every one of them under both assumptions.

Ermites del Pla is the one to plan for. 81.8 km of it — beginning at kilometre 37 — passes no public tap at all, and it crosses 58 places that could fill a bottle if they happen to be open. That is not a route with no water on it. It is a route whose water has opening hours.

At the other end, Serra de Tramuntana - Central 1 carries 9 taps and still puts 35.9 km between two of them. There is no route on this island where the tap layer alone will carry you.

The climbs, and the last place to fill

A climb is where the bottle actually empties, and it is also where the refill stops existing: the counters are in the village at the bottom and the pass is in a nature reserve. Of the 72 published climb-sides this measurement could walk, 42 have no public tap anywhere on them and 11 have nothing of any kind — no bar, no shop, no fountain, from the foot to the summit.

Where the riding is, the water is not

The pattern in the table is not random and it is not about mapping. It is the island’s shape. The counters cluster where people sleep and eat — the coast, the resort towns, Palma — and the riding goes the other way, up into a range whose villages are small and whose passes are protected. So the gap opens exactly where the effort is.

The base towns show it in one column. Across the 18 towns with a page here, Cala Millor is 9.6 km by road from the nearest public tap, and Sóller is 13 metres from one. 6 of the 18 are more than five kilometres from a tap — and every single one of them has somewhere to buy a bottle within a few hundred metres of the middle of town.

That column is a hotel-shopping column as much as a water column: it is the difference between filling two bottles on the way out of town and starting the day with a detour.

The tap you find may not be one you should drink

There is a second question underneath the first, and on this island it is not rhetorical. Spain’s Ministry of Health publishes, network by network, the laboratory bulletins for every public water supply — the date the sample was taken and its verdict, in the register’s own words. As the register stands: 12 of the 53 municipalities on Mallorca have at least one distribution network whose latest published bulletin is not «AGUA APTA PARA EL CONSUMO».

The practical reading is short. In those municipalities, fill from a bottle you bought, not from a tap you found — and note that a bar’s tap is on the same network as the fountain in the square, so “I’ll ask inside” is not a way round it. Everywhere else the register says the supply is fit on the most recent sample it publishes, which is a statement about the mains and not about a spring on a hillside. Nothing here says anything about a torrent, and nothing should: they run after rain, through farmland, and they are not a water source.

What riders say, and whether it holds

The best account of this problem was not written by a guide. It is a rider’s trip report on a German forum, under a heading that just says «Trinkwasser»:

That is this page’s own finding, arrived at from the saddle rather than from a graph — the public network is thin, so you end up depending on hospitality and shops, which outside the tourist towns close in the afternoon. He remembers exactly two public taps. Our measurement attaches 213 of them to the road network. Both are right, and the reason is the point of this page: the taps exist, and they are not where a visiting rider rides.

Four claims in this survey touch our own records, so they are checked rather than repeated.

Two more, both worth having because they name a place rather than a principle. Dagmar Behringer, «Die 15 ultimativen Rennradrouten auf Mallorca» treats the Coll d’Honor as a training benchmark and fills up first: «Vorher noch am Marktplatz die Trinkflaschen am Brunnen auffüllen – und los.» — and the measurement says why that matters. There are taps on the square, and then the climb runs 5.5 km to the pass with nothing at all. On the other side of the range, a German training-camp write-up points at Lluc: «Wenn ihr oben angekommen seid und die Flaschen auffüllen möchtet, bietet sich das Kloster Lluc oder die bekannte Tankstelle nebenan an.» — the monastery and the filling station beside it, which is the same Repsol this site already measured sitting on the summit of the Coll de sa Batalla.

And then there is the advice that names nothing. A hire operator’s own page tells riders to fill reusable bottles «an öffentlichen Brunnen und Wasserstationen auf der Insel» and does not name one fountain on the island. That is the genre this page exists against.

Know before you ride

The siesta is a water problem, not a lunch problem. The forum report puts it exactly right: the places you are relying on are shut in the afternoon outside the tourist towns. A ride that leaves at seven and gets to the far side of the Serra at two is a ride planned around a bar that is closed.

Sunday and Monday close villages, not resorts. The counter layer above counts what exists, not what is trading. In a mountain village in February the difference is most of it.

A reservoir is not water. Cúber and the Gorg Blau are the island’s drinking-water supply and you pass both on the highest road on Mallorca. You may not drink from them, and there is no tap at either.

July is the month this stops being an inconvenience. The mean daily maximum at Palma airport in July is 31.2 °C, and the same 81.8 km you rode in March in arm warmers is a different physiological event. The month page has the rest of the numbers.

Carry the means to buy, not just to drink. Every gap on this page shrinks to nothing if you have a way to pay in a village shop. On the routes above, the difference between the two columns is between 66.7 km and 26.7 km of dry road.

So: two bottles or three?

Three, on anything that crosses the Serra, and fill both of the first two at the last village before the climb rather than at the hotel. The measurement says the decisive stretch is not the climb — it is the road on either side of it, where you are moving fast, drinking steadily and passing nothing.

Two is enough on the plain and the coast, where the counter layer is dense and the gaps in the table close to a few kilometres — as long as you are riding in hours when the counters are open.

Two plus a way to buy, if you would rather not carry a third and you are riding a route with a village on it. That is most riders, most days, and it is a legitimate answer; it is only the wrong answer on the days and the hours when it is quietly not.

The practical block

If the booking is still open, the water column is a real tie-breaker. Two towns that look identical on climbs can differ by five kilometres on the way to a tap, and that is a detour on every ride of the week. The table above is the shortlist — Sóller and Port de Pollença sit at opposite ends of it — and the base guide ranks the same towns on the riding.

If you are hiring a bike, ask about the cages before you ask about the groupset. A third bottle needs somewhere to go, and a frame with two cages and no saddlebag mount is a two-bottle bike whatever you intended — compare hire bikes before you arrive and the hire guide has what the operators publish.

And if you are still choosing the rides, the trip planner composes the week from the same records this page is measured on, so the routes it hands you are the routes in the table above.
