Lake Saint Anne

Lake Saint Anne is Romania's only volcanic lake, located in the heart of Transylvania, within the Kozmás–Tusnád–Lázárfalva area of the Csomád–Bálványos region. Its crystal-clear waters and the crater walls, shaped like a candlestick, exude a mystical charm while carrying a deeper message: the importance of safeguarding and sustainably preserving natural treasures.

Lake Saint Anne – A Natural Sanctuary and Model for Sustainable Tourism

Lake Saint Anne is one of Europe’s most unique volcanic lakes, nestled in the depths of the Csomád crater and surrounded by picturesque woodlands. The lake captivates visitors not only with its beauty but also with the responsible approach that has defined tourism development here in recent years. The crystal-clear waters, bird-song-filled trails, and surrounding protected areas – including the Mohos Peat Bog – offer an experience that is both memorable and sustainable.

Sustainability in Practice

Developments around Lake Saint Anne have been carried out in an exemplary manner: the aim is not to cater to mass tourism but to ensure regulated visits while preserving nature. To protect the lake’s water quality, complex ecological interventions have been implemented in recent years: fish stock management, vegetation control, sediment removal, and continuous monitoring of water parameters all contribute to the long-term preservation of this unique habitat.

Here, sustainability is not an empty slogan but a tangible reality: visitor behaviour guidelines, eco-friendly infrastructure, restrictions on vehicle traffic, and nature-focused hiking trails all encourage respect for the environment.

Experiences Throughout the Seasons

In the summer months, lakeside walks, hiking trails, and guided tours provide relaxation, while in winter, designated sledging slopes – subject to snow conditions and supervision – make the area special. Nearby, the Mohos Peat Bog can be visited with a guide, where the unique bog habitat and volcanic past come to life. Local communities – landowners and service providers – play an active role in protecting the lake and managing tourism.

Activities Around Lake Saint Anne

The Lake Saint Anne area offers a variety of activities for nature lovers, families, hikers, and those seeking tranquillity – all year round. The uniqueness of the offerings lies in the fact that every experience is closely tied to nature and sustainability.

Hiking and Nature Walks

The hiking trails around the lake are well-maintained and clearly marked, allowing visitors to safely explore the crater lake’s surroundings. Particularly popular is the trail leading to the Saint Anne Lookout, which offers breathtaking panoramic views. Along the trails, information boards help visitors learn about the area’s natural values.

Guided Tours to the Mohos Peat Bog

The nearby Mohos Bog, with its unique sphagnum moss habitat and rare plant species (e.g., carnivorous sundew), can only be visited as part of a guided tour. The expert guidance not only ensures safety but also adds depth to the experience – offering insights into the formation of the landscape and the ecological role of the bog.

Winter Sledging

When weather permits, a sledging slope over 1,000 metres long awaits families and winter sports enthusiasts near the lake. Sledging takes place under regulated conditions with proper safety supervision – a unique experience in Transylvania.

Quiet Retreat and Nature Observation

Spending time by the lake, meditating, birdwatching, or simply enjoying a picnic can be deeply fulfilling – especially for those seeking spiritual renewal away from urban noise. Conservation rules provide a framework for mindful presence, while the tranquillity of the lake truly slows one down.

Photography and Nature Observation

The area’s wild beauty, changing light, dense pine forests, and unique water reflections offer excellent subjects for nature photography enthusiasts. The lake floating in morning mist, the play of autumn colours, or the snow-covered crater are particularly popular themes among photographers.

Every activity here is aligned with nature and the spirit of the place – the site offers no artificial attractions but instead fosters a genuine, meaningful connection with natural heritage. This is why many consider Lake Saint Anne not only one of Transylvania’s but also Central Europe’s most valuable sustainable tourism destinations. 

What Is Not Allowed at Lake Saint Anne? – Protecting Nature Is a Shared Responsibility

Lake Saint Anne is a strictly protected area, and visits are regulated to ensure that its natural values remain intact and its ecological balance is preserved in the long term.

Visitors are strictly prohibited from the following activities:

  • Driving to the lake – the lake is only accessible on foot, and cars must be left in the upper car park. Transfers are occasionally provided for expectant mothers, people with disabilities, and those with health conditions to access the area. 
  • Swimming in the lake – the water body is a closed ecosystem, and human interference would cause severe damage.

  • Water sports – no equipment is allowed on the water. An electric boat provides an alternative water experience.

  • Feeding or disturbing wildlife, especially brown bears – this can also be dangerous.

  • Playing loud music, shouting, or making noise – the silence around the lake is one of its greatest assets.

  • Lighting fires or barbecuing – open flames and cooking are not permitted.

  • Littering or disturbing natural habitats – even the smallest interference can cause irreversible damage.

  • Camping or pitching tents near the lake – this is only allowed in designated areas, not on the lakeshore.

The protection of nature is supported by information boards, guides, and regional regulations, but above all, the awareness and respect of visitors is paramount. At Lake Saint Anne, the “leave no trace” principle is not just a recommendation but an expectation – ensuring that others can enjoy the same experience.
