Key facts at a glance
May is the greenest month in the region and the best one for water. Snowmelt means streams, gorges and waterfalls carry more water than at any other time. Walking in the valley and at middle altitudes is fully possible, while snow still lies higher up. The summer lifts and the big high-altitude destinations only start during the month or later. May is quiet, inexpensive and scenically strong, but it is not a month for high-alpine tours or lake swimming.
If you want to see Zell am See-Kaprun at its most intense, come in May. Snowmelt fills every stream, the meadows on the valley floor are lush green, and white peaks still stand above them. At the same time it is quiet, because the summer season has not yet begun. That is a very good deal, provided you know what you are signing up for.
Weather in May
On average, valley highs reach around 18 degrees, cooling to roughly 5 degrees at night. May is therefore pleasantly mild, but also one of the wetter months. Afternoon showers and thunderstorms are typical, particularly in the second half. Starting in the morning statistically gives you the better odds.
Water as the main attraction
May is the month of maximum water flow, which makes several destinations far more impressive than in high summer:
- Sigmund Thun Gorge: the Kaprun stream forces its way through the ravine at full power in spring. Details and walking times in the gorge guide and getting there and parking.
- Streams and waterfalls in the national park: the Hohe Tauern shows its most dynamic side in May, see Hohe Tauern National Park.
- Lake Zell: the shore is green and empty, ideal for walks and photographs, background in Lake Zell.
Hiking: yes below, not yet above
The rule of thumb in May is that everything up to around 1,500 metres is comfortably walkable, and above that it becomes progressively tricky. High-level paths still carry snowfields, individual sections can be closed, and old snow is more slippery in spring than it looks. Stay deliberately at middle altitudes in May. Suitable routes are collected in the hiking guide, easier variants in easy walks on the Schmittenhöhe, and for guided options see guided walks.
What starts in May
May is a ramp-up month. The Grossglockner High Alpine Road opens after snow clearing and is one of the region’s great driving experiences. The Kaprun high mountain reservoirs and the Lake Zell boat service only begin, depending on the year, towards the end of May or in June. Exact dates shift with the snow, so please check them currently.
Cycling comes into its own in May. Valley routes are clear, temperatures are agreeable and there is little traffic. Starting points in cycling, e-bike and road cycling.
Who May suits
May is ideal for walkers at middle altitudes, cyclists, photographers and anyone seeking quiet and fair prices. Couples in particular will find an unusually relaxed region, with ideas in a romantic weekend. It is less suited to swimming holidays, high-alpine summit tours and families set on the full summer programme with every lift running. For that, summer from June onwards is the right time.
Frequently Asked Questions
Can you hike in Zell am See in May?
In the valley and at middle altitudes, yes, and very well. The paths around Lake Zell, in the Kaprun valley and on the lower slopes are snow-free and exceptionally green. High-level routes above roughly 1,800 metres may still hold snowfields and can be partly closed.
Is Lake Zell suitable for swimming in May?
For most people, no. The lake only warms to comfortable temperatures in June. In May the water is still well below that, though the shore makes for lovely walking and photography.
Is the Grossglockner High Alpine Road open in May?
Usually yes, it opens after snow clearing in spring. Exact dates and daily access times vary with snow conditions, so check before you drive.
Why is May good for photography?
Because three things coincide: maximum water flow from the snowmelt, fresh green in the valley and still snow-covered peaks above. That contrast is no longer available in July.
