An award-winning establishment: one of the best spas in the world!

The Yonaguni Spa at the Yona hotel (formerly Parc Hôtel) in Obernai has already won several awards at the World Luxury Spa Awards: Best Unique Experience Spa, Best Luxury Country Spa, Best Day Spa… This gives you an idea of the level of what awaits you?

I’ve been there several times and it’s one of my favorite spas in Alsace! It joins my favorites La Cheneaudière and La Source des Sens.

The mysterious world of Yonaguni Spa in Obernai

To dive into the universe of Yonaguni Spa, we can already look at the origin of this name which does not sound very Alsatian… And for good reason, it is the name of an underwater island in Japan, which is quite mysterious and could be the remains of a disappeared city. That’s what makes you want to escape, don’t you think?

The spa invites you to enter a mysterious universe, offering you the possibility to live a moment out of time and exceptional the time of a Day Spa!

The spa has several areas: the aquatic world, saunas (panoramic, black and banya), steam rooms and relaxation areas. The Yonaguni Spa is truly immense: it covers 3,000m2!

The different areas: a 3,000 m² sensory labyrinth

The aquatic world: losing track of time in the pools

All the areas are aesthetically pleasing, but what really stood out for me was the 350m2 aquatic world. It looks like a kind of labyrinth: corridors lead to a dozen different rooms with multiple atmospheres, with various water jets, and you lose track of time when you walk through! The materials used are raw while being very contemporary, the mixture is really successful!

A large swimming pool with huge windows also completes the set, with different water jets to test.

Saunas, steam baths and waterfalls: heat rituals

On the second floor of the spa you will find various types of showers and waterfalls as well as saunas and steam rooms. Plan to spend some time testing everything!

Absolute relaxation in the rest rooms (and salt grotto)

The relaxation areas are also incredible. I won’t tell you everything so that you can keep some surprises, but I have a particularly good memory of the waterbeds of the salt cave, for example…where I fell asleep with a wonderful sleep!

Day Spa package: gourmet lunch at the Yuzu Bar

Lunch (for Day Spa) or dinner (for Night Spa) is included in the package. It is served at the Yuzu bar, which is only reserved for the spa’s customers (bathrobe atmosphere, it’s nice!).

A buffet is served from 11:30 a.m. to 2:30 p.m. or from 6:30 p.m. to 8 p.m., and you’re in for a treat. A wide choice of raw vegetables, various dishes and desserts await you, and everything is of high quality.

Additional services: massages and treatments at extra cost

If you wish, you can of course book additional treatments or massages.

Stay at the Yona Hôtel d’Obernai to extend the experience

If you want to extend the pleasure, you can of course book a stay at the Yona Hôtel d’Obernai: the rooms are all delightful and comfortable. Access to the Yonasaya spa is included in the room rate, and there are special rates for spending a half-day or a full day at the Yonaguni Spa.

FAQ: Everything you need to know for your visit to Yonaguni Spa (YONA)

How far in advance do I need to book the Yonaguni Spa?

The spa is extremely popular. For a Day Spa package, I advise you to book several months in advance, especially if you’re aiming for a weekend. For Night Spa, availability is often a little more flexible, but you should still plan ahead for 3 to 4 weeks.

The hotel parking lot is reserved for residents. For day or evening guests, the easiest way is to park in the free Altau public parking lot, just 150 metres from the spa entrance.

What’s the difference between Day Spa and Night Spa?

Both packages offer 6 hours’ access to the facilities. Day Spa includes buffet lunch at the Yuzu Bar, while Night Spa (evening) includes buffet dinner. It’s easier to book the Night Spa, which is a little less popular.

Is a bathing suit compulsory at Yonaguni?

Yes, unlike some German spas, bathing suits are mandatory in the aquatic world and pools. Bathrobe, towels and slippers are provided on arrival.

Is the spa child-friendly?

No, access to Yonaguni Spa is strictly reserved for people aged 16 and over, to guarantee the tranquility and Zen atmosphere of the place.
