Crio High Trail

The trail is best hiked during the warmer months, typically from late spring to early autumn. Be aware that the steep cleft at the back of the reservoir can be hazardous in heavy rain and impassable in winter due to snow and ice. Always check local conditions before you go.

The terrain varies significantly. The initial section follows a mountain road across the Luzzone Lake dam and along its south bank to Alp Garzott, which can be straightforward and gravelly. From Alp Garzott, the marked hut trail begins with a steep ascent. You'll traverse a steep cleft, navigate a river crossing, and climb winding switchbacks through sparse larch forest. The final stretch to Motterascio Hut is a steep, serpentine path.

While specific restrictions are not mentioned, this is a challenging alpine hike requiring good fitness and sure-footedness. If bringing a dog, ensure it is accustomed to strenuous mountain terrain, steep ascents, and potential river crossings. Always keep dogs under control, especially around grazing cattle at Trachee.

The hike typically starts from Lago di Luzzone. Parking is usually available near the dam or along the access road. It's advisable to arrive early, especially during peak season, to secure a spot.

There are no specific permits or entrance fees required to hike this trail. However, if you plan to stay overnight at Capanna Motterascio, you will need to book accommodation and pay the hut fees.

You'll be treated to magnificent panoramic views throughout. The journey starts alongside the impressive Lago di Luzzone, nestled like a fjord. The path leads through a gorge, past a waterfall (Ri di Mutarasc), and through areas with beautiful mountain springs adorned with gentians and alpine roses. You might also see cattle grazing at Trachee. Upon reaching Capanna Motterascio, expansive views from the high plateau await.

Capanna Motterascio (also known as Capanna Michela) is a renovated, modern SAC hut located at 2,172 meters above sea level. It provides accommodation in small dormitories and serves as an excellent base for further alpine tours into the expansive Greina high plateau. It also offers food and drinks.

Public transport options to Lago di Luzzone can be limited. It's best to check current bus schedules for the Blenio region, as services might be infrequent, especially outside of peak season. Driving and parking is often the most convenient option for accessing the trailhead.

Yes, this route is a popular approach to the Plaun la Greina, a unique tundra-like landscape. It also intersects with sections of other official trails, including the 07-Via Alta Crio, Capanna Motterascio - Garzott, Larecc - Diga del Luzzone, and Zervreila - Diga del Luzzone.

Given its challenging alpine nature, you should bring sturdy hiking shoes with good ankle support, appropriate layers of clothing for varying weather conditions, rain gear, plenty of water, snacks, a map or GPS device, and a first-aid kit. Trekking poles are highly recommended for the steep ascents and descents.

The initial section of the trail, following the mountain road across the Luzzone Lake dam and along its south bank to Alp Garzott, can be straightforward and is even accessible with prams in some gravelly sections. However, beyond Alp Garzott, the marked hut trail becomes very steep and challenging, making it unsuitable for prams and young children without alpine experience.
