Lake Neuchâtel is the largest lake entirely within Switzerland. Known for its shimmering waters and tranquil atmosphere, it offers a perfect escape during the warmer months. But before planning a lakeside getaway, one question comes up often: what’s the water temperature? And what can you actually do around the lake? Here’s everything you need to know — plus why Hôtel Beaulac is the ideal base for your stay.
How warm is Lake Neuchâtel?
In May, the lake is still fresh — expect water temperatures between 12°C and 14°C. It’s brisk, but invigorating for those who enjoy a cooler dip or a pre-breakfast swim. June is more pleasant, with temperatures rising to 19–21°C, and occasionally reaching 23°C during a heatwave.
By July and August, Lake Neuchâtel reaches its peak: 24°C to 26°C is common, with some years seeing up to 27°C or 28°C. Even September is suitable for a swim, with waters remaining around 20°C.
Where to swim near Hôtel Beaulac?
One of the great advantages of staying at Hôtel Beaulac is its direct proximity to the water. Just a few steps from the reception, you’ll find several beaches and swimming areas:
Plage des Jeunes-Rives: A local favourite just a 5-minute walk away. With its grassy lawn, shaded trees, snack kiosk and calm waters, it’s perfect for families or a casual afternoon by the lake.
Plage de Monruz: A bit further along the promenade, this beach is quieter and offers a more natural setting for those seeking a peaceful swim.
Plage de Serrières: Located on the edge of town, this spot is known for its sunset views and tranquil vibe — ideal for an end-of-day dip.
On the water: boat hire and lake cruises
Right outside the hotel, the harbour offers various water activities. You can board a boat with the LNM (Navigation on the Lakes of Neuchâtel and Morat) for a scenic cruise to Estavayer, Yverdon-les-Bains, or even Murten.
Prefer to steer your own adventure? Sun’n’Paddle, located by the Jeunes-Rives beach, offers stand-up paddleboards for hire. If you’re looking for a motorboat (no licence required), check out Nautic Shop Neuchâtel. For a more complete nautical experience, the Les Vikings base in Yvonand rents kayaks, sailboats and offers wakeboarding lessons.
Strolling lakeside or hiking along the shore
The lake is not only for swimming — it also offers some of the region’s most relaxing walks. From Hôtel Beaulac, a paved promenade leads to the Esplanade du Mont-Blanc, with views of the Alps and lakefront benches ideal for quiet reflection.
Further afield, the Grande Cariçaie nature reserve on the southern shore of the lake is a must-visit. Spanning over 40 km, this protected area is a haven for birdwatchers, nature lovers and hikers. The easiest access is from Yverdon-les-Bains, a short train ride from Neuchâtel.
Hôtel Beaulac: comfort and elegance by the lake
Whether you’re coming for a long weekend, a mid-week retreat or a family holiday, Hôtel Beaulac offers a calm, stylish base right on the lake. Many rooms and suites offer views of the water or the Alps, and breakfast is served on a terrace overlooking the harbour.
For lunch or dinner, the Lounge Restaurant offers creative cuisine featuring local products, while the rooftop bar WAVES is perfect for an evening cocktail with panoramic views.
