About St. Martins Therme & Lodge
St. Martins Therme & Lodge, Austria is a paid thermal spa resort at Im Seewinkel 1 in Frauenkirchen, Burgenland, on the edge of the Neusiedler See - Seewinkel National Park, a UNESCO World Heritage landscape on the Pannonian Plain. The facility is Austria's only lake-therme with its own bathing beach, set on a private 8-hectare lake. The thermal water is drawn from 860 metres and rises at 43 degrees Celsius, classified as a sodium-hydrogen carbonate-chloride mineral water and recognised as Burgenland's third official healing spring. The resort combines a 4-star superior lodge hotel with a public thermal spa open to day visitors.
Pools, Sauna, and Facilities
The day therme includes indoor and outdoor thermal pools, five saunas and steam baths, an infrared lounge, and a showering experience area. Premium add-on zones, the Galleries and the Relax! Upper Deck, provide all-inclusive sauna access including the lake sauna. The children's area with its own pool and slide is acoustically separated, and a free supervised childcare station runs nature-themed activities. From May to September, the Summer Island outdoor area gives access to the private lake with beach and lawn. Lodge guests access a separate See-Spa with Finnish and soft sauna, steam bath, and direct lake access, reserved for guests aged 14 and over.
Location & Access
Getting to St. Martins Therme & Lodge
St. Martins Therme & Lodge is at Im Seewinkel 1 in Frauenkirchen, reached by taking the A4 motorway east from Vienna, exiting at Neusiedl am See and following regional roads south through Podersdorf to Frauenkirchen and the Seewinkel district. From Vienna Schwechat airport the drive takes approximately 50 minutes. An airport transfer is available by prior arrangement. The nearest train station is Frauenkirchen, served by regional rail from Vienna's eastern connections; a taxi from the station reaches the resort in a few minutes. On-site parking and electric vehicle charging are available. The resort occupies an isolated position in open national park countryside, and hot springs near Frauenkirchen in this flat Pannonian setting are distinctly different in character from alpine thermal destinations.
Practical Access Notes
Day visitors enter the thermal spa through the public entrance separately from lodge guests. The Summer Island lake area is seasonal, operating from May to September, and supplements rather than replaces the indoor pools which are open year-round. Advance reservation is recommended for the premium Galleries and Relax! Upper Deck areas, for spa suites, and for massage treatments. The lodge is set within the national park zone, with the Seewinkel's birdlife and nature visible from the pool and lakeside terrace areas.
Suitability & Accessibility
Who St. Martins Therme & Lodge Suits
St. Martins Therme & Lodge suits couples and adults seeking a nature-immersive spa experience in a national park setting, and families who benefit from the separated children's zone, the free supervised childcare station, and the outdoor lake in summer. The safari-lodge aesthetic, guided Seewinkel Ranger experiences, and the UNESCO landscape give the venue a character unlike conventional alpine thermal spas. For visitors seeking a Thermalbad in Austria combining healing spring water with genuine wilderness surroundings, this is one of the most distinctive options in the country. The facility is wheelchair accessible and barrier-free throughout, with accessible parking on site.
Planning Your Visit
Day visitors can access the full therme without lodge accommodation. The premium Galleries and Relax! Upper Deck areas within the spa require a separate booking and include all-inclusive sauna access including the lake sauna, which is not part of standard day entry. The Summer Island beach area is available to both day visitors and lodge guests from May to September. Spa suites with lake views are limited in number and should be reserved in advance. Guided nature experiences through the resort's Ranger programme are available year-round and can be booked as part of a stay or independently for day visitors.
Safety & Etiquette
Safety at St. Martins Therme & Lodge
St. Martins Therme & Lodge is generally safe for soaking and family bathing, operating as a staffed managed resort with trained personnel throughout. The thermal water enters pools from a 43-degree Celsius source; visitors should allow time to acclimatise and test temperatures before extended soaking, as individual heat sensitivity varies. The private 8-hectare bathing lake is monitored and maintained to high water quality standards, but open-water swimming requires more caution than pool bathing; children should be supervised near the lake at all times and should only use designated swimming areas.
Sauna, Children, and Rules
The See-Spa exclusive to lodge guests is restricted to guests aged 14 and over. Public sauna areas in the day therme follow standard Austrian conventions, with towels used as bench bases and swimwear typically not permitted in traditional sauna rooms; visitors unfamiliar with this should confirm current rules on arrival. The children's area is acoustically separated and has its own pool, slide, and a free supervised nature-themed childcare station; parents should remain close to younger children at all times. Medical conditions including cardiovascular conditions and pregnancy warrant a consultation with a medical professional before soaking in 43-degree thermal mineral water. Valuables should be stored in lockers. The rural national park location means hospital facilities are in Neusiedl am See or Eisenstadt, so visitors with ongoing medical needs should plan accordingly.
