One&Only Portonovi

Boka Bay and the Adriatic Luxury Shift

The Bay of Kotor is a fjord-like inlet that cuts deep into the Montenegrin coastline, ringed by limestone karst and medieval fortifications that have accumulated UNESCO World Heritage designation. For most of the early 2000s, the area attracted independent travellers and sailors rather than luxury resort guests. That changed incrementally, then decisively. The Regent Porto Montenegro in Tivat established a superyacht-anchored marina model in the western bay, while the Ananti Resort Residences & Beach Club in Reževići pushed further down the Adriatic coast. The arrival of One&Only Portonovi in 2021, on the eastern shore near Herceg Novi, completed a rough triangle of upper-bracket hospitality around the bay and confirmed that this stretch of coastline had moved from emerging to established on the international luxury circuit.

At the time of opening, Portonovi was One&Only's first European property, a signal of how far the brand believed the region had matured as a destination. The 2026 La Liste Leading Hotels ranking awarded it 97.5 points, placing it in company with properties that compete across a much larger established-luxury peer set. For context on the wider Adriatic luxury conversation, Aman Sveti Stefan operates further south along the Montenegrin coast, offering a different aesthetic proposition: a restored medieval island village versus Portonovi's contemporary bayfront resort grammar. The two properties are not direct substitutes; they draw on different design languages and attract somewhat different guest profiles, though both pitch at the highest price tier in the country.

The Dining Programme: Four Registers, One Kitchen Culture

The most revealing thing about how One&Only Portonovi positions itself within the broader Adriatic resort market is the architecture of its food and beverage programme. Where comparable resorts in the region often run a single all-day restaurant and a pool bar, Portonovi operates four distinct dining formats, each with a clear culinary identity. This is the model One&Only has deployed at its Caribbean and Middle Eastern properties for years, and importing it to the Balkans represents a bet that the Adriatic guest is now prepared to engage with the same level of dining complexity that drives resort spend in the Maldives or Dubai.

Sabia is the Italian-focused anchor, positioned steps from the waterline and built around seasonal produce and Adriatic seafood. The menu reads as a composed Italian offering with local inflection: oysters sourced from the bay, spaghetti with red prawn ragu, and whole fish baked in a sea salt crust. The approach mirrors what Italian coastal restaurants have been doing for decades, but the setting and service register place it firmly within the resort's luxury frame rather than in the trattoria register that dominates the coastline's independent scene. For a broader read on what local and independent dining in the area looks like alongside the resort tier, our full Herceg Novi restaurants guide covers the range.

La Veranda operates across two distinct modes depending on the time of day and season. Breakfast and dinner run throughout summer; in winter, a lunch service is added, making it the year-round operational core of the property's food offering. The evening format is where La Veranda makes its clearest statement: local Montenegrin lamb alongside Japanese wagyu and Australian wagyu, with fresh catch of the day as the pescatarian constant. The wagyu-and-local-lamb combination is a structural choice that appears at resort restaurants across the Mediterranean luxury tier, positioning the kitchen as a place where regional identity and international luxury reference coexist on the same menu.

The pool-anchored concept, Tapasake, runs a Japanese-Peruvian small plates format with raw preparations as its signature. Nikkei cuisine has become a default language for premium pool-adjacent dining globally, appearing with similar logic at resorts from the Côte d'Azur to the Greek islands. Portonovi's version focuses on raw bites alongside tacos and tempura, calibrated for daytime grazing rather than formal dining. The format works precisely because it is low-commitment dining that allows guests to eat well without leaving the pool environment.

Caminetti bar completes the circuit with afternoon tea, a classic cocktail list, and grazing plates including a slider trio and poke bowl. The afternoon tea programme, with Paris-Brest and vanilla mille-feuille among the sweet offerings, borrows a format associated with European grand hotel culture and is coherent with the broader One&Only brand positioning. A daily wine tasting in the Providore cellar, led by the head sommelier and paired with Montenegrin cheese and charcuterie, gives guests structured access to local wine production in a setting that removes the friction of finding a specialist tasting elsewhere.

Chenot Espace and the Wellness Proposition

European destination spas have split into two broad categories: hotel spas that offer treatments as an amenity, and medically inflected wellness centres that offer structured programmes as the primary reason to visit. The 43,000-square-foot Chenot Espace at Portonovi operates in the second category. Chenot is a Swiss wellness methodology built around multi-day holistic plans that integrate nutrition guidance, cardiorespiratory fitness assessment, and scientifically framed massage and therapy protocols. The Portonovi facility is among the larger European outposts of the Chenot approach, and for guests whose primary motivation is wellness rather than beach resort leisure, it functions as a destination within the destination. The spa is large enough, and the programme structured enough, to make a stay of four to seven days purpose-built rather than incidental.

Architecture, Rooms, and the View

The 123 rooms, suites, and villas were designed by Belgian architect Jean-Michel Gathy, whose portfolio spans several of the most recognisable luxury resort projects of the past two decades. The design language at Portonovi draws on traditional Montenegrin residential architecture: centrepiece fireplaces appear in suites and villas as a formal reference to local domestic interiors, while floor-to-ceiling windows are oriented toward Boka Bay. The fireplace detail is more than aesthetic; it extends the property's usable season into autumn and early spring, when the bay is calm and the surrounding mountains are snow-capped but the temperature makes open-air dining impractical. The 123-key count places Portonovi at a scale where personalised service is structurally possible, in contrast to the large-footprint resorts that dominate the Croatian coast.

For readers comparing against other design-led properties in the broader Mediterranean luxury set, reference points include Castello di Reschio in Lisciano Niccone and Casa Maria Luigia in Modena, both of which pursue a regionally rooted design identity at a comparable key count. Within the One&Only peer set globally, the Portonovi model is closest in spirit to how the brand has approached its Indian Ocean properties: rooms oriented toward a dominant water view, a multi-concept F&B programme, and wellness as a structural anchor rather than an add-on.

Excursions and Local Context

One&Only properties have built a consistent offering around guided excursions that position the hotel as a gateway to its immediate geography. At Portonovi, the programme includes guided tours of nearby medieval villages along the winding roads above Herceg Novi, hiking with local mountain guides into the karst terrain, olive grove visits with olive oil tastings, and island-hopping by boat across Boka Bay. The excursion format is the resort's primary mechanism for connecting guests to a coastline and culture that extends well beyond the property boundaries. Our full Herceg Novi experiences guide covers what is available independently for guests who want to supplement or extend the resort programme.

The KidsOnly club, themed around Jules Verne's 20,000 Leagues Under the Sea, runs watersports, raft building, and treasure hunts, positioning the property as suitable for multi-generational travel without compromising the adult-focused calm that the spa and fine dining require. This dual-register operation, serving families and wellness-focused adult couples simultaneously, is a structural feature of the One&Only brand that Portonovi executes within the bay's specific geography. Boutique Hotel Casa del Mare Mediterraneo offers an alternative for guests seeking a smaller-scale, independent property in Herceg Novi without the full resort infrastructure.

Planning Your Stay

One&Only Portonovi operates as a seasonal property with its full F&B programme running during summer months; La Veranda adds a lunch service in winter, making the quieter season viable for guests whose priority is the spa rather than the beach. The resort sits in the Portonovi Resort complex in Kumbor, approximately five kilometres from Herceg Novi's old town. Tivat Airport is the nearest international entry point, served by seasonal direct flights from major European hubs, with Dubrovnik Airport in Croatia as the primary alternative for year-round access. Guests travelling for multi-day Chenot wellness programmes should treat the spa booking as the primary reservation and room category as secondary; for leisure and beach-focused stays, bay-view suites and villas offer the most direct engagement with the property's central asset, the Boka Bay waterline.

Frequently Asked Questions

Which room category should I book at One&Only Portonovi?

The strongest case for the higher room categories rests on the Boka Bay views, which are the property's dominant environmental asset. Jean-Michel Gathy's floor-to-ceiling window design means that suites and villas with direct bay orientation deliver the view as a constant rather than an occasional feature. For guests visiting primarily for the Chenot Espace spa, the room category matters less than proximity to the wellness facilities; in that case, a standard room with bay outlook is a reasonable base. The 97.5-point La Liste ranking and the One&Only tier both imply that even entry-level rooms sit well above the regional baseline for comfort and finish.

What is One&Only Portonovi leading at?

The Chenot Espace spa is the most distinctive facility in the Adriatic luxury set at this scale: 43,000 square feet of medically structured wellness programming that functions as a destination in its own right rather than a hotel amenity. The four-concept dining programme is the most architecturally ambitious F&B offer in Herceg Novi's luxury tier. For guests whose primary measure is setting, Boka Bay framing in a 123-key property with a Jean-Michel Gathy interior is the specific combination that places Portonovi at the leading of the regional peer set on design credentials. The 2026 La Liste 97.5-point award provides an external validation of where the property sits against the global luxury hotel field.

How hard is it to get into One&Only Portonovi?

As a seasonal Adriatic resort, Portonovi's peak demand concentrates in July and August, when bay access, pool dining at Tapasake, and the full F&B programme run simultaneously. Booking four to six months ahead for peak summer dates is advisable, particularly for villa categories and any multi-day Chenot wellness programmes, which have independent availability constraints. The shoulder months of May, June, and September are structurally easier to book and offer the bay's leading weather-to-crowd ratio. Winter stays are feasible for wellness-focused travellers and should be booked with direct confirmation that the specific spa programme required is available on those dates.

Is the Chenot Espace spa at One&Only Portonovi suitable for a standalone wellness retreat, or is it only for hotel guests?

The Chenot Espace at Portonovi is designed around multi-day holistic wellness plans rather than single-treatment spa visits, making it most effective as the organising purpose of a stay rather than a single afternoon activity. The 43,000-square-foot facility covers nutrition guidance, cardiorespiratory fitness, and scientifically structured therapies in a format that requires several days to deliver its intended protocol. Guests planning a Chenot programme should treat the spa schedule as the primary booking and build their length of stay around the programme duration, which typically runs from four to seven days depending on the selected plan.
