Ibiza can be downright cozy in the offseason

The party was over. Yet some were still trying valiantly.

"No Closing," exclaimed a cherry red billboard on the side of the two-lane highway as I steered my rental car away from the lone airport in Ibiza, Spain. "The Party Goes On."

But, no, it didn't. Not really. And that's why I was visiting Europe's dance-party capital in fall.

During the height of summer, Ibiza teems with Europeans who crowd into vast nightclubs to ingest questionable substances and dance until morning. After sleeping all day, the story goes, they wake up and do it again. And again. And maybe one more time. And then they go home.

From October to May, the boompboompboomp of those thunderous nightclubs drifts largely away, and the island returns to a place celebrated for its subtler charms: rocky coasts, swooping, pine-studded hills and thousands of years of history in the midst of the Mediterranean Sea.

Warm with the knowledge that the party people were back home, I rolled down my windows to take in the sweet-salty air and made the 10-minute drive to Ibiza City, the island's largest city. It has been continuously inhabited for nearly 3,000 years, which makes it one of Europe's oldest cities.

Ibiza City seemed immediately familiar and like so many well-preserved European haunts, where twisting one-way streets are flanked by stone sidewalks and stucco buildings and where boys kick soccer balls in a tree-shaded plaza surrounded by restaurants and cafes. Up the hill, at the city's highest point, sat the Old Town, circled by a mighty stone wall. Down at the marina, the tall spines of sailboats swayed in a 70-degree breeze.

Ibiza — or, Eivissa, as spelled locally in Catalan — wasn't always the party island.

Situated about 100 miles east of the Spanish mainland, it is one of the three major Balearic islands settled by the Phoenicians in the seventh and eighth centuries B.C. The island has passed through many hands, including the Carthaginians, the Romans, the Moors (one guide told me radical Islamists want the island returned to Muslim rule) and self-rule before becoming part of Spain.

The club scene sprouted roots in the 1980s. Fueled (allegedly) by the drug Ecstasy, Ibiza's reputation inched from one of Mediterranean beauty and a hippie backwater to a party place. Spanish tourism officials have attempted to maintain the opulent party while also somewhat minimizing it to promote the island for lower-key travelers — hikers, divers, kayakers and sightseeing families.

The tourist season runs from February into October, with the party patrol on hand mostly from June through September. Most locals I met said the best months to be on the island are, therefore, May and October, with June and September following closely behind. Hot and claustrophobic, they said, July and August are best left for those chasing the fiesta.

As I picked through tapas at a restaurant in the old town (octopus, albondigas and red wine — the usual), a couple who had recently moved from England said the streets where we sat would be jammed during the height of summer. "Gazillions of people," the man said.

During the next few months, the number would only continue to decrease. But Ibiza is open for business year-round, which makes a trip timed with the holidays a worthy effort, particularly because temperatures still reliably reach the upper 50s. Many restaurants and shops are closed, but not all. And many hotels remain not only open but offer exquisite low-season deals. Crowds are nil, and the best of what the island offers — sweeping rock-cliff views into the moody Mediterranean, nature and endless tapas and vino tinto — remains ample.

Those nonparty charms were quickly apparent. Like the salt. Ibiza salt is a thing, and it's a thing you'll find in the island's better restaurants. At Locals Only — one such Ibiza restaurant whose name amplifies its locally sourced food, not the clientele it prefers — each table was topped with a glass jar of the white crystals.

"It is natural," said my waitress, who had a solid command of English, like most people I met on the island. "There is no — how do you say? — chemical process."

I ground a little of it into my hand, and it came out almost as powder. It tasted like salt. Though possibly with less chemical process.

Soon lunch began to arrive, starting with a bowl of glistening green olives and a basket of crusty bread beside a bottle of locally produced olive oil.

I popped an olive into my mouth. Yes, it was that good. It wasn't just plump and salty; there were layers of flavor weaving between briny anchovy and bright lemon zest. It was a small, subtle revelation.

At breakfast the next morning on the plaza square, Placa d'Espanya, I ordered tomato and manchego cheese on a baguette and watched people chat in rapid Spanish, read newspapers and smoke cigarettes. It was all so quaintly normal. I began to wonder if the island's party reputation was overstated. Life was so gentle and ordinary.

Although a massive cruise ship sat quietly in the marina after unloading the latest batch of visitors, the long row of businesses facing the water were closed that afternoon — No. 5 Ibiza, Angelo's Bar and El Bucanero restaurant. I wondered whether this was a result of the afternoon siesta or if they were closed for the season.

That night, about 10:30, I walked by again, looking for the answer. Sure enough, everything remained closed. The lone exception, Foly's Cafe, offered a vision of what all those storefronts probably present during the height of tourism season: men on white furniture smoking cigarettes over small cups of coffee, a television flashing with a soccer game. It wasn't difficult to imagine the strip teeming with revelers in July. On this night, it was still as a forest.

As I wound my way back to my apartment through the narrow stone streets of the old city, several bars were open and several more were just starting to put out tables and chairs in anticipation of a long night.

On a walk the next morning to the other side of the Ibiza City harbor, I found out what I was missing. The two sides of the harbor couldn't have been more different. Across the harbor from the Old Town sat Ibiza's version of 1970s Miami Beach — sprawling, mostly soulless hotels, condos and apartment buildings beside a boardwalk of bikers, joggers and slow-moving families reveling in the sweet Mediterranean air.

Billboards touted the recently completed "closing parties." These are significant events in Ibiza and give the party season its official end. I had (thankfully) missed them by a couple of weeks at clubs named Space, Ushuaia and Amnesia. Evidence of the clubs was everywhere, mostly in the form of billboards for those closing parties and round stickers tagged to cars and light poles. A few cars were covered completely in cherry stickers as homage to Pacha (the club that pledged "No closing").

On an island of 220 square miles, the clubs are mostly confined to Ibiza City and a town 10 miles northwest, called San Antoni, which has none of the historic charm but does feature a gem of a walking path that winds along the glimmering sea. On a tranquil, breezy afternoon, past shuttered restaurants and bars, it was hard to imagine the landscape ever full of people.

But it is, said the owner of an ice cream shop on the stretch, where flavors such as estrachatela (chocolate chip) and Nutellina (Nutella) beckoned. The owner, an Israeli, said he would be closing from November through April, even though he would be staying on the island. Except for the downturn in ice cream demand, it's a wonderful time to be here, he said.

The deeper you venture into the island, the further you get from any trace of party culture. Much of the island is simply quiet pine forest crossed by curving two-lane highways and dotted with the occasional palm tree or cactus.

"March," she said.

The season had ended two days earlier.

She urged us to visit the charming little town of Santa Gertrudis, which is home to a wide square ringed with restaurants, but they were all closed due to a power outage from that morning's storms.

We instead improvised with a drive down the island's west coast to a series of beach towns. We wound up on a small beach below gray skies with a front-row view of the quintessential sight from Ibiza: a pair of small islands, Es Vedra and Es Vedranell, just off the coast.

On we went to Es Xarcu, a beachside restaurant at the end of a steep dirt road that seems unlikely to be there. But there it is — an unsuspecting little shack with exorbitant prices because you're on Ibiza, you're on the beach and you're eating fresh-from-the-sea fish in a small Mediterranean cove.
