Hiking

Embark on the Sentiero del Fiume Meria Trail, a challenging hike that follows the Meria river through a wild and serene landscape. This difficult route covers 5.5 miles (8.8 km) and involves a significant elevation gain of 1978 feet (603 metres), taking approximately 4 hours and 10 minutes to complete. You will discover numerous waterfalls, cascades, and crystal-clear pools, including unique natural basins known as "marmitte dei giganti," as you navigate the varied terrain.

This trail is best suited for experienced hikers with a good level of fitness and familiarity with mountain environments. Be prepared for several river crossings; water levels can make these more challenging, and you might get your feet wet. It is essential to bring enough food and water, as there are no refreshment points available along the main path. Plan your visit carefully to ensure you have adequate daylight and energy for the duration.

The Sentiero del Fiume Meria Trail is nestled within the Grigne Special Protection Area, offering a unique natural experience. The route features sections equipped with metal ropes, chains, and steps to assist you over rocky and exposed areas, adding to the adventure. As you hike, you can look forward to panoramic views of Lake Lecco and the impressive Grigna Settentrionale mountain, especially on your return journey, and a peaceful stop at Alpe di Era.

Natural pool with waterfall in Grigna Meridionale

Highlight • Waterfall

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.

Along the Meria River Pools Path you will have the opportunity to immerse yourself in uncontaminated nature. A fun trail that takes you past sparkling waterfalls and crystalline pools, from Sonvico to Alpe Era, where a small sanctuary awaits you. Bring with you hiking boots, spare socks and – if the weather permits – your swimsuit! Some pieces must be tackled by attaching themselves to the chains.

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!

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.

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

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

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.

The climb via signpost 15a is wonderful only when it hasn't rained in the mountains, you walk over some very exposed climbs due to the river.
But really fantastic to follow the river upstream.
Backward via marker 15 simple alpine path
Everything very well described

Showing Translation

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!

At Alpe d'Era along the initial stretch of the Sentiero del Fiume. The point where the Stiri bridge allows you to cross the Meria stream is suggestive. Rejoining the usual route through a steep path that comes out near the sanctuary of Santa Maria sopra Olcio.
Alpe d'Era is always very pretty.

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!
