About Son Spa
Son Spa, Norway is a 4-star spa hotel on the Oslofjord waterfront in Son, Vestby municipality, Akershus, approximately 40 minutes from Oslo by car. The hotel opened in November 2008 and is part of the Strawberry Hotels group. It sits between two beaches on the Son shoreline, with its own marina, and the town of Son, known for its maritime history and art galleries, is within walking distance of the hotel entrance.
The spa covers 2,000 square metres across two floors and is the central feature of the property. It includes three indoor pools, outdoor hot tubs, saunas, and steam rooms. Two floating saunas on the hotel pier have sauna masters leading daily aufguss rituals followed by a cold sea plunge. The Circle of Senses signature concept guides guests through a sequence of spa stations with a personalised product kit. Massage, body wraps, and specialised treatments are available by appointment.
Activities beyond the spa include kayaking, RIB excursions, Tai Chi on the pier, and a fitness studio. A restaurant serves seasonal meals; breakfast is included for hotel guests. A cocktail lounge and lobby bar are open in the evenings.
Location & Access
Getting to Son Spa
Son Spa is at Hollandsvn. 30, 1555 Son, on the Oslofjord waterfront. From Oslo, take the E6 south and follow signs toward Vestby and Son; the drive takes approximately 40 minutes. The hotel has paid underground parking (Obepark), which charges per night; check current rates when booking as parking is not free. Street parking in Son is limited.
By public transport, take the local bus from Oslo or a train to Son station. The airport express bus from Oslo connects to Sonsveien station, making the hotel accessible without a car for visitors staying overnight. From Moss Rygge Airport, Son is approximately 25 kilometres by road. The hotel is also accessible by boat; Son Marina is directly adjacent to the property, so guests arriving by sea can moor and walk to reception.
Son itself is a well-known summer destination along the Oslofjord, with galleries, cafes, and a harbour atmosphere in the summer months. The town is quieter in winter, when the pier saunas and hot tubs are particularly appealing. For guests looking for hot springs near Oslo within easy reach by car or public transport, Son Spa is the most developed fjord spa hotel on the western side of the fjord south of the capital. A conference centre with 14 meeting rooms accommodating up to 150 people makes it a popular choice for corporate retreats combining work and wellness.
Suitability & Accessibility
Who Son Spa Suits
Son Spa suits adults aged 16 and over seeking a full-service fjord spa hotel experience within easy reach of Oslo. The minimum age of 16 for all spa facilities applies to hotel guests and day visitors alike. The venue is particularly suited to couples, groups of friends on spa weekends, and solo wellness travellers. The combination of indoor pools, floating pier saunas, sea plunge, and the Circle of Senses spa journey offers a more structured experience than most Norwegian floating sauna facilities.
Hotel guests receive complimentary access to the spa and breakfast is included. Day visitors can purchase spa access and treatments directly; check sonspa.no for current day visit packages and pricing. The spa is one of the larger and more established accessible hot springs options near Oslo, with the full hotel infrastructure, lift access, and disabled guest facilities making it more suitable for visitors with mobility needs than pier or floating sauna alternatives. Guests with specific accessibility requirements should contact the hotel directly before booking to confirm which spa areas and pool levels can be accessed.
A range of spa packages and seasonal offers is on the hotel website; midweek stays offer better value than weekend rates, which sell out more quickly. The two floating pier saunas are popular; ask at check-in about availability. Treatments should be pre-booked, especially during peak season from May through September and over Norwegian public holidays.
Safety & Etiquette
Son Spa Safety Tips
Son Spa is a professionally managed hotel spa with trained staff throughout the facilities. The indoor pools, saunas, steam rooms, and outdoor hot tubs are maintained to Norwegian hospitality standards. Begin sauna sessions at 10 to 15 minutes and take cool-down breaks between rounds. Drink water before and during your spa visit. People with cardiovascular conditions, low blood pressure, or pregnancy should seek medical advice before using saunas, steam rooms, or hot tubs. The aufguss ritual saunas on the pier reach high temperatures; first-time sauna visitors should let the sauna master know and take a conservative approach to the first session.
The sea plunge from the pier is voluntary. The Oslofjord at Son sits at approximately 2 to 4 degrees Celsius in winter and around 18 degrees in summer. Enter using the pier access point rather than jumping; keep cold dips brief and return to the sauna or indoor warmth promptly. The pier surface can be slippery when wet and icy in winter; move carefully between the sauna cabin and the water. The minimum spa age of 16 applies to all areas including the pier saunas and sea plunge.
The spa has a long, steep staircase between the changing area and the lower spa pool level, as noted by guests in reviews. Allow extra time for transitions between floors and take care on the stairs, particularly in wet feet. Heavy doors separate some spa zones; take these slowly. Paid underground parking is available at the hotel; the parking structure is narrow and requires careful manoeuvring in larger vehicles. If arriving for a day visit, confirm your booking and check-in procedure with the hotel reception before heading to the spa area.
