Access is via a very accessible path, 900 m from the last parking lot. You can also park in the parking lot just to the left of the departmental road, which is 1400 m from the path.

The Alloix waterfalls are the perfect way to escape the heat of the day. The main event is the Grand Cascade, at the very top, with a height of 43 meters. But the waterfalls located on the way are also worth mentioning. The Gouille tuff waterfall is one of the most remarkable.

The region boasts several impressive waterfalls. The Alloix Waterfalls feature the Grand Cascade, a breathtaking 43-meter drop. The Cirque de Saint-Même Waterfalls in the Chartreuse massif are well-known for their series of four distinct cascades within a dramatic cirque. Additionally, the Cascade de la Pisserotte, also in Chartreuse, stands over 60 meters tall, offering a powerful display, especially in spring.
Spring is often the most impressive time to visit, as snowmelt increases the water flow, making cascades like the Cascade de la Pisserotte particularly powerful. Autumn also offers beautiful scenery with changing foliage, as noted for the Cirque de Saint-Même Waterfalls. Some waterfalls, like Pissou Waterfall, can even be seen frozen in winter, offering a unique experience.
Yes, visitors have recommended swimming just below the Dioux Waterfall, describing it as a refreshing and almost magical stopover. Always exercise caution and check local conditions before entering the water.
The waterfalls around Theys and in the surrounding Isère department are generally accessible via well-maintained hiking trails.

The hike to the Cirque de Saint-Même Waterfalls is described as short and easy, with a 7 km loop available for more exploration.
