Sevilla is the hen-weekend capital of Europe. We can finally explain why.

We did not set out to study hen weekends. We set out to figure out why Sevilla, on a per-capita basis, is booked by groups of women aged 26 to 38 at roughly four times the rate of any other Spanish city.

The answer turns out to be one of urban geometry, climate, and dinner culture.

The weather window

Most European cities have a four-month window when group travel works. Sevilla has nine. Average daytime highs from March through November sit between 19°C and 33°C, and the famously brutal summer can be sidestepped by booking the shoulder months — when the orange trees are out, the streetside dinners run until midnight, and there is no queue at any tapas bar that does not have a Lonely Planet sticker on the door.

For a group trying to find a weekend that works for six people, a nine-month window is a structural advantage. There is, simply, more time to land on dates everyone can do.

The rooftop density

Sevilla's old town has, by our count, 38 hotel and bar rooftops within an 800-metre radius. The next densest city we measured, Lisbon, has 14. Rooftop density matters more than it should, because rooftop bars are the natural habitat of a group of six dressed up for the evening: open layout, photogenic lighting, no one needs to lean over a stranger to talk.

A group of six that walks into a normal bar splits in half. A group of six on a rooftop stays a group of six.

Dinner at eleven

Sevillanos eat late. Group dinners begin at 22:00, sometimes 23:00, and finish past midnight. This is, counter-intuitively, ideal for groups travelling together. Late dinner means a long, slow afternoon — siesta, pool, a cheap manicure, a leisurely shower. The day is structured around the social meal, not the other way round.

Compare this to a city where dinner is at 19:30: the day fragments. People disappear at 16:00 to "get ready," reconvene at the table tired, and then someone wants to be in bed by 22:30.

The data

We see this in the booking data. Groups travelling to Sevilla stay, on average, 3.4 nights — longer than Madrid (2.6) or Barcelona (2.9). They book more activities per day. They split the bill more evenly. And they leave better reviews.

We have not yet figured out whether Sevilla creates the perfect group trip, or whether the kind of group that books Sevilla is already pre-disposed to good weekends. Probably both.

What to do there

Three rooftops we send everyone to: La Terraza del EME, Doña María, and Hotel Las Casas de la Judería (least famous of the three, best of the three). One restaurant: El Rinconcillo, the oldest bar in the city, opened in 1670, still has the same staff. One thing not to do: a flamenco tablao for tourists. Walk into a regular bar after midnight in Triana instead.
