The stream, in its flow through the rocks, has carved them and has created numerous pools of transparent water that invite you to dive. The rocky walls surrounding us are never too high and offer the possibility of repeating dives from different heights several times. In the final part, there are some spectacular passages between narrow rocky walls where we find dives and scenic descents. An old dam marks the end of the descent. From here, about ten minutes of walking take us back to the parking lot.

The geographical position makes Rio Lerca easily accessible from other regions such as Tuscany, Lombardy or Piedmont, therefore making it ideal for combining a weekend at sea with a fun and exciting sporting activity such as canyoning, or as a stop during a holiday. The optional feature of the higher dives means that even very heterogeneous groups can enjoy the descent, each according to their level and motivation.

If Rio Lerca has entertained and motivated you, you can move to the French border and discover Val Roya and its famous canyons.

Rio Lerca is a beautiful stream, a pearl, still little frequented compared to the beauty of the place. Some pools are frequented during the summer, but few, even among the locals, know the entire route and make the complete descent. In a sunny and bright valley, a few kilometres from Genoa, we find a canyon where aesthetics and fun magically combine. Although close to the coast, we will have the impression of being isolated and far from the world. The route has a series of low-recessed waterfalls that offer alternation of dives and natural slides in pools of transparent and crystalline water.

Practicable from May to October, this canyon lends itself perfectly both to those who are looking for emotions and to those who want to enjoy a day immersed in the beauty of nature.

Once the technical material is distributed, a forty/fifty-minute walk awaits us, rather steep in the initial half hour. To avoid excessive heat, we will try to leave early in the morning and face the climb quietly. At the start of the river, you will receive all the necessary information on safety and progression in the stream.

From the first waterfall, there is a situation that will be repeated many times during the day, that is, the possibility of choosing between abseiling and diving.

Rio Lerca hides in the valleys of Mount Beigua right next to Genoa.A few kilometres from the motorway exit, crossing the suburbs, we find ourselves in a stunning landscape. An open and bright valley practically uninhabited, which makes you think of some remote place in Corsica and offers the opportunity for a day of sport and nature in complete tranquillity. The canyon is also easily accessible from other regions; just know that only two hours of highway separate us from Milan, for example.

General information

The 130 metres in altitude are distributed along a descent of 1.5 km and have a large number of waterfalls, never too high, at most 10 metres. Few are the abseils that are truly essential, and they are never impressive. Numerous dives are possible, even relatively high, but never mandatory.

Vertical features

It can be frequented starting from May, with a water level that can still be important and that makes the descent sporty. When the flow rate becomes regular, the descent is also accessible to beginners. The swimming parts are never too long and do not have particular complexities. The temperature of the water is never cold, and the exposure to the sun makes the descent particularly pleasant.

Aquatic features

The descent alternates more recessed and suggestive parts with much more open ones. Along almost the entire route, you can quickly get out of the river. The transparency of the water and the adhesion of the rock greatly facilitate progression. At the height of a large pool called Lagu du Mei, there is the possibility of leaving the stream with an easy path.
