If you're asking what is the most romantic resort in Costa Rica for couples, Tabacón Thermal Resort & Spa is the answer most travelers arrive at, and for a specific, irreplaceable reason. A natural thermal river, volcanically heated and flowing through lush rainforest gardens at the base of Arenal Volcano, is the feature that no other property in the country can replicate. That single distinction, combined with a well-regarded open-air spa and the adults-only Shangri-La Gardens, makes Tabacón a widely cited benchmark for thermal-and-spa-focused romantic stays and the number-one property on TripAdvisor's 2026 romantic hotels list in Costa Rica. Still, the country offers a wide range of impressive options: adults-only clifftop villas on the Pacific coast, secluded rainforest casitas in the Arenal region, and boutique oceanview retreats designed specifically for honeymooners.
This guide ranks the best romantic resorts by region and feature set, using four consistent criteria: privacy and adults-only access, natural scenery and aquatic or thermal experiences, spa quality, and exclusive amenities. By the end, you'll know which two or three properties match your priorities and exactly what to ask before you book.
Key takeaways
- Top romantic resort: Tabacón Thermal Resort & Spa ranked on the top 3 romantic hotels list in Costa Rica on TripAdvisor's 2026 , with a 4.6/5 rating, and is consistently recognized for its natural volcanic thermal river and adults-only Shangri-La Gardens. Note that other publications may identify different leaders across Central America.
- Adults-only distinction matters: Fully adults-only properties offer child-free environments throughout, not just in a designated zone.
- Region shapes the experience: Arenal delivers volcanic thermal springs and rainforest; Guanacaste offers beach and dry-season sun; the Southern Pacific provides biodiversity and dramatic ocean views.
- Airport choice affects arrival: SJO is roughly 3 hours from Tabacón and Arenal resorts; LIR puts couples 1 to 2 hours from Guanacaste and Pacific coast properties.
- Book early in high season: December through April is peak season, and the most in-demand romantic resorts, including Tabacón, sell out weeks or months ahead.
What is the most romantic resort in Costa Rica for couples? Quick answer
Not every resort that uses the word "romantic" in its marketing earns the label. Four specific factors separate the properties that deliver a truly intimate experience from those that simply offer a king bed and a nice view.
Private settings and adults-only access
There's a meaningful difference between a fully adults-only resort and a family property with a roped-off adults-only pool. At a fully adults-only resort, the entire atmosphere shifts: quieter gardens, unhurried service, and none of the ambient energy that traveling families bring. For honeymooners and couples celebrating milestones, this distinction is not minor. There are resorts that enforce adults-only policies across the entire property, while other resorts, like Tabacón, offer a designated adults-only section within an otherwise family-friendly environment.
Natural scenery and thermal or aquatic experiences
A hotel pool, however beautifully designed, doesn't do what a natural thermal river does. Access to a wild natural element, whether a volcanic hot spring, a private beach, or a jungle waterfall, creates a sense of place that no manufactured amenity can replicate. This is the core reason Tabacón's thermal river carries such weight in any honest ranking: it's the only natural, volcanically heated, untreated thermal river in Costa Rica flowing directly through a resort property. That experience is categorically different from soaking in a pool heated by a geothermal system off-site.
Couples' spa offerings and exclusive amenities
A genuine couples' spa experience means treatment bungalows set within living rainforest, signature rituals using locally sourced volcanic ingredients, and private hydrotherapy access. This is not the same as a side-by-side massage table in a standard treatment room. The best romantic resorts in Costa Rica build their spa programs around the natural environment. When evaluating any property, look for open-air or rainforest-integrated treatment spaces, private thermal or hydrotherapy access, and the option to book couples' rituals rather than just parallel individual treatments.
Why Tabacón is the most romantic resort in Costa Rica for couples
Tabacón Thermal Resort & Spa sits at the base of Arenal Volcano in La Fortuna, and its position at the top of this list is not a matter of branding. TripAdvisor's 2026 ranking of romantic hotels in Costa Rica places Tabacón at the top 3, with a 4.6 out of 5 rating across more than 1,000 properties. That recognition reflects what guests consistently describe: a natural experience so distinctive that it reframes what a romantic resort stay can feel like.
The volcanic thermal river that flows through your stay
The thermal river at Tabacón is heated by Arenal Volcano itself, continuously renewed with mineral-rich water and entirely untreated. It winds through the resort's tropical gardens in a series of pools and waterfalls at varying temperatures, from cooler refresh pools to deeply warming soaks. You choose your temperature, your pool, your moment. No other resort in Costa Rica has direct access to anything like it. This is the line that separates Tabacón from every competitor on this list: the thermal experience is not a recreation of nature, it is nature.
Adults-only access in the Shangri-La Gardens
The Shangri-La Gardens are Tabacón's exclusive adults-only section, and access feels like stepping into a more private version of an already extraordinary resort. Quiet thermal pools, uninterrupted rainforest views, and a pace set entirely apart from the broader resort grounds define the space. For couples who want the immersive scale of a full resort alongside the intimacy of a child-free retreat, the Shangri-La Gardens offer both without compromise. Contact Tabacón directly to confirm the current age policy for Shangri-La Gardens access.
Couples' treatments in open-air rainforest bungalows
The open-air spa at Tabacón operates from treatment bungalows surrounded by living rainforest, far removed from any lobby energy. The signature Idyllic Massage, a 105-minute couples' experience, combines full-body massage, facial care, volcanic-mud foot treatment, and a private outdoor Jacuzzi with a milk bath and fresh fruit. Pricing varies and should be confirmed at booking. Hot-springs day-access packages are also available for those not staying on-site; confirm current spa access policies with the resort when booking to understand all available options.
Best romantic resorts for couples who want Pacific coast and ocean views
The Southern Pacific and Manuel Antonio regions offer a different kind of romance: dramatic sunset backdrops, biodiversity-rich rainforest, and a slower pace shaped by the sound of the ocean rather than a volcano.
Kura Boutique Hotel (Uvita)
Kura is adults-only with only eight luxury suites, including standalone villas set within rainforest with panoramic Pacific views. Its open-air design and small scale make intimacy unavoidable. The property is best for couples who value minimalist architecture and the kind of sunset moment that genuinely stops conversation. The sense of closeness here comes from intentional design, not just limited capacity.
Vista Celestial (Uvita)
Vista Celestial offers private villas with plunge pools and panoramic views of both jungle and ocean, with a level of personalized service that scales naturally to a small, adults-only guest count. Its position in the Southern Pacific makes it ideal for couples who want to pair their resort stay with visits to Marino Ballena National Park, where humpback whale sightings are possible depending on the season. That description, purpose-built for honeymoon privacy, is accurate, not aspirational.
Makanda by the Sea (Manuel Antonio)
Makanda by the Sea is adults-only, with rainforest villas, private beach access, and gourmet dining in a secluded boutique setting. It offers something relatively rare in Costa Rica: rainforest lodging and direct ocean access in a single adults-only environment. For couples who want the drama of a jungle canopy above and the Pacific below, Makanda earns serious consideration.
How to choose the right romantic resort for your Costa Rica trip
The ranking above answers which resorts are best. The questions below help you determine which one fits your specific priorities, from thermal immersion to coastal scenery, and from boutique seclusion to full-service resort scale.
| Resort | Location | Adults-only | Thermal/aquatic feature | High-season rate (approx., as of 2026) | Best for |
|---|---|---|---|---|---|
| Tabacón Thermal Resort & Spa | Arenal / La Fortuna | Shangri-La Gardens (adults-only zone) | Natural volcanic thermal river | From ~$2,540 for 3 nights | Unmatched thermal experience, spa rituals, rainforest immersion |
| Casa Chameleon at Las Catalinas | Guanacaste | Fully adults-only | Private infinity pools (ocean-facing) | ~$1,150/night | Coastal scenery, stylish architecture, ocean views |
| Kura Boutique Hotel | Uvita (Southern Pacific) | Fully adults-only | Infinity pool with Pacific views | Contact resort | Minimalist design, dramatic sunsets, extreme privacy |
| Makanda by the Sea | Manuel Antonio | Fully adults-only | Private beach access | Contact resort | Rainforest plus direct ocean access |
Match the region to your romantic priorities
The Arenal and La Fortuna region delivers volcanic thermal springs, dense rainforest, and easy access to adventure activities like zip-lining and white-water rafting, making it ideal for couples who want to combine recovery and adrenaline in the same trip. Guanacaste is the Pacific coast choice: consistent dry-season sunshine from December through April, beach settings, and ocean-facing architecture. The Southern Pacific, anchored by Uvita and Manuel Antonio, offers the most dramatic biodiversity alongside ocean views, though it receives more rainfall year-round. The region you choose shapes the entire character of the trip, not just the hotel backdrop.
What to ask before booking a couples or honeymoon package
Use these questions when comparing properties to avoid surprises on arrival. Is the adults-only policy enforced throughout the entire property, or only within a single designated zone? What does the couples' package include versus what is priced as an upgrade? Are spa treatments available poolside or only in dedicated treatment rooms? Is thermal facility access included in the room rate or purchased separately? Clear answers to these questions make it straightforward to compare packages across properties on equal terms and find the one that delivers what matters most to you.
Getting there from U.S. airports: SJO vs. LIR
Costa Rica is served by two international gateways. Juan Santamaría International Airport (SJO) near San José is approximately 3 hours by road from La Fortuna, making it the natural choice for couples headed to Tabacón and the Arenal region. Private transfers run around $240 for up to four passengers and should be booked at least 72 hours in advance with your flight number provided. Liberia Airport (LIR) in Guanacaste puts couples 1 to 2 hours from the north Pacific coast properties. Direct flights from major U.S. hubs serve both airports. Many high-end Costa Rica resorts publish prices in U.S. dollars and commonly have English-speaking staff available; confirm currency and language support with each property directly.
What is the most romantic resort in Costa Rica for couples? Plan your trip before the dates are gone
For couples looking for a romantic experience that exists nowhere else, Tabacón Thermal Resort & Spa is the clear first choice. The volcanic thermal river, the Shangri-La Gardens, and the open-air spa bungalows create a combination that no private villa or ocean-view suite can replicate on its own. That's not a branding claim; it's the reason Tabacón is ranked among the top 3 spots on TripAdvisor's 2026 romantic hotels ranking across more than 1,000 Costa Rican properties.
The other resorts on this list are strong within their respective categories. The right pick comes down to whether volcanic thermal immersion, Pacific sunsets, or rainforest seclusion matters most to you and your partner. Casa Chameleon delivers a polished adults-only coastal experience in Guanacaste. Kura, Vista Celestial, and Makanda by the Sea lead the Southern Pacific options for couples drawn to ocean views and biodiversity.
High season in Costa Rica runs December through April, and the most romantic properties at every price point book out weeks or months in advance during that window. If your question is what is the most romantic resort in Costa Rica for couples, our recommendation is Tabacón for its one-of-a-kind volcanic thermal river. Contact the Tabacón reservations team directly to confirm current availability, ask about the Wellness Experience package, and secure your dates before the season fills.
Frequently Asked Questions
When should I book to secure a room at the most romantic resorts in Costa Rica during high season?
Book as early as possible, because high season runs December through April and the most in-demand romantic resorts sell out weeks or months ahead. I recommend securing reservations well in advance of your travel dates to avoid disappointment and to lock in preferred room types or adults-only areas like Tabacón's Shangri-La Gardens.
How much do private transfers cost from San José (SJO) to La Fortuna or Tabacón?
Private transfers run around $240 for up to four passengers from SJO to La Fortuna. I advise booking those transfers at least 72 hours in advance and providing your flight number when you reserve the transfer.
Can non-guests visit Tabacón's hot springs without staying at the resort?
Yes, hot-springs day-access packages are available for those not staying on-site. I suggest contacting the resort directly to confirm current spa access policies and day-pass availability before you go.
Do high-end Costa Rica resorts commonly publish prices in U.S. dollars and offer English-speaking staff?
Yes, many high-end Costa Rica resorts publish prices in U.S. dollars and commonly have English-speaking staff available. I still recommend confirming currency and language support with each property directly when you book.
