Hiking

Embark on the Sentiero del Fiume Meria Loop, a difficult hiking route that takes you deep into the narrow, incised Meria Valley. You will follow the Torrent Meria, encountering numerous waterfalls and crystal-clear pools along the way. This challenging 4.5-mile (7.2 km) loop involves a significant climb of 1499 feet (457 metres), requiring about 3 hours and 21 minutes to complete. The terrain is varied, featuring natural paths, alpine sections, and parts equipped with chains and steps, giving it a unique feel. As you ascend, you'll pass the tranquil Alpe d'Era, offering a moment of calm before reaching viewpoints with panoramic vistas of the Grignetta and Lake Lecco.

Before you set out on this difficult hike, make sure you are well-prepared and wearing sturdy shoes. The route demands good physical training due to its challenging nature. It is crucial to plan your visit during dry periods for the best experience. Heavy rains can significantly increase the difficulty of the trail, as higher water levels in the Torrent Meria can make some crossings much more demanding. Always check weather conditions before heading out to ensure a safe and enjoyable adventure.

This trail stands out for its unique blend of traditional hiking and via ferrata-like elements, making it more than just a walk in the park. The journey through the deeply incised Meria Valley offers a distinct natural environment within the Zona di Protezione Speciale Grigne. You will experience a dynamic landscape, from following the torrent to reaching elevated points that provide expansive views over Lake Lecco and Mandello, especially near the Santa Maria Sopra Olcio Church. It's a route that truly immerses you in the rugged beauty of the region.

Santa Maria Sopra Olcio is a Romanesque church with a single nave. In the presbytery you can admire some sixteenth-century frescoes such as the Madonna with child and the saints Lorenzo and Rocco. The bell tower dates back to the 11th century and has kept part of its original construction. The building that incorporates the church was enlarged with the structure of the convent and with rooms to accommodate wayfarers.

Meria Stream Waterfall

Highlight • Waterfall

A beautiful waterfall that gently slides into the river, silent, almost noiseless, as if it were cotton. A few hundred meters from the arrival in Alpe Era, not to be missed!

Of the whole path this is certainly the most scenic pool, and also the one where it is possible to swim. The pool as well as having a beautiful waterfall, is also large and deep enough to be able to immerse yourself completely. Be careful though! The water is very cold and the rocks slippery. The use of sea shoes is recommended.

At some points of the route, especially in the second part, you pass by some rocks, but nothing complicated, but I recommend adequate footwear.

Climb all via ferrata no children and dogs ... beautiful but challenging for us inexperienced ... Return from Era descent to a stone staircase but quiet

Translated by Google

The river path (15b) that we took on the way there has several rather challenging sections on rocks with chains. Furthermore, in several places you have to cross the river. This route is not recommended after heavy rain. The return path, however, is simple and passable.

Uphill always along the river... Several river crossings, some passages for climbing (secured with chains). Lots of waterfalls and pools. Very beautiful. Downhill paved path, very beautiful but not so adventurous

Translated by Google

The tour is tough for casual hikers. Some climbing experience or talent is required, particularly towards the end of the climb. The varied path along the intoxicatingly beautiful stream, which must be crossed many times, makes up for this. You can't go wrong with waterproof hiking boots. Swimwear is definitely recommended; the pools and small lagoons are very tempting!

Translated by Google

If you like places that are rarely visited, full of waterfalls and pools like the giants' potholes, very wild, where nature reigns supreme and the trail offers adrenaline-filled moments without being dangerous, on sultry days this is a route that deserves an A+....long live nature, please always respect it!

Translated by Google

Unfortunately my battery gave up on the way down the station with 1.9 km to go. Still a very demanding but great hike. I took a change of shoes with me with water sandals through the river and hiking boots for the rest. 🥾Really spectacular hike for experienced hikers.
