The border village of Castasegna lies on the mountain slope between the Mera River and the Brèntan plateau and is known for the surrounding vast chestnut forest. The village is made interesting by the vernacular architecture of its old centre, the many old fountains and washing troughs, and the more sophisticated Villa Garbald (1862). The nearby Casnàc ruins, on flatland beyond the Mera, are worth mentioning, as well as the Caslàc tower (rebuilt in 1891) on the northern slope. The Brentan chestnut forest is one of the largest in Europe. Of the village’s two reformed churches, the SS. Trinità church dates back to 1660, while the one dedicated to st. John the Baptist was first mentioned in 1408.
The fourth stage of the trails starts between the confectioner’s shop, and the post office. The trail will lead you to the river through the lower part of the village. You will cross the river on the stone bridge and start up the incline on ample hairpin turns, glimpsing chestnut groves and old cattle sheds. After 45 minutes you will get to a road that will take you down to Bondo. Bondo lies at the foot of a mountain that blocks out the sun and leaves the village in the shade during three months every winter. The most important building is the Salis Palace, built in the second half of the eighteenth century by the Grisons ambassador to the English court Geronimo Salis-Soglio. On the small square stands the S. Martino church. On its façade old frescoes were recently brought back to light. The trail will leave the village centre behind and take you to the Valle Bondasca on an uphill winding road. Just before the bridge, the trail will bend and lead you on a steep track to Cugian. On the way you will enjoy breath-taking views of the Bondasca valley and the Sciora range. In Cugian you will walk the dirt road leading down to Ceresc. Half an hour before getting to Ceresc, the trails will bend to the right and will steeply cut through the woods to the road below leading back to Bondo. On the same road you took at the start of the excursion you will head back down Castasegna.

Protected areas, proposed Emerald sites, Natura 2000 sites
WWF-proposed Emerald site Val Bregaglia:
Southern, almost Mediterranean wildlife characterizes the Val Bregaglia, with altitudes varying from 700 to 3300 m. The landscape is rich with chestnut woodland and dry meadows and generally high biological diversity. The site is shared by the municipalities of Bondo, Castasegna, Soglio, and Stampa. The most frequent habitats are dry meadows and wetlands.
The Val Bregaglia is an IBA (Important Bird Area), an internationally recognized stopover area for migratory birds. The identification and description of IBA’s (a BirdLife project) was instrumental in the designation of the Special Protection Areas of the EU Natura 2000 network.
WWF’s tips for hikers
Plan each stage carefully, purchase a 1:25000 map, use light but sturdy equipment (hiking boots, rain cape, binoculars…). Be sure to carry a small supply of water and food. We suggest you taste local food (possibly organic) at resting places and restaurants.
Do not litter, do not pick up flowers or rocks and in no way disturb the local fauna. It is unsafe for inexperienced hikers to leave the marked trails and it may cause disturbance to wildlife.
