Val Lumnezia (Valley of Light) branches off to the south at Illanz where it divides into the Ober and Unterlugnez (Upper and Lower Lugnez). The Valsertal branches off the Lugnez. The rural Alpine valley of Lugnez lies in front of the majestic silhouette of the Piz Terri (3159m). At the end of the valley, the Diesrut-Pass (2428m) leads to the sparse Greina High Plateau and further over the Greina Pass into the Valle di Blenio and Canton Ticino.

Sights worth seeing at Lumbrein include various churches and chapels in the village and surrounding areas, Lumerins Castle und the Casaulta (tower). The oldest settlement on Lumbrein territory is the hilltop settlement at Surin, which was inhabited as early as 1500 BC. The traditional buildings date mainly from the 18th and 19th century; the original landscaping and appearance of the villages in the valley have been largely preserved to this day. Lumbrein has been home to Casa d'Angel, a centre of the arts featuring exhibitions and events since 2015.

Summer

This area of natural beauty has several hiking routes and many interesting theme trails. A regional hikers’ bus takes hikers to the starting points of their trails. There is a signposted network of routes for mountain bikers. Hikers and bikers can recover from their exertions by taking a swim in the lake at Davos Munts near Vattiz. .

Winter

There are winter ski bus connections from Lumbrein to the ski region Val Lumnezia / Mundaun / Obersaxen. The three ski regions are linked in a joint ski-pass network, which means skiers can travel on 18 lift installations serving a 120 km network of easy to moderate pistes at altitudes of 1200 to 2300 metres with a choice between the sun-exposed south-orientated Lugnez slopes (downhill piste from Piz Sezner, 2310 m along the flanks of the Mundaun chain to Lumbrein) and the north-facing shaded deep-snow pistes on the Obersaxen side.

Non-skiers can enjoy 50 km of winter hiking trails, snow shoe trails and sledging routes.
