Lucomagno Pass to Biasca

The road runs south from Disentis and climbs, with moderate gradients, through the Höllenschlucht (Hell's Gorge), a magnificent wooded defile. It then continues uphill, with numerous bends, and passes through a number of tunnels, between which there are views to the rear of Disentis Abbey and later impressive views of the foaming waterfalls in the gorge below.

The road leaving the Valle Santa Maria runs down the Val Blenio, high up on the south side of the valley, with magnificent views of the valley itself, the precipitous buttresses of the Rheinwaldhorn, the Cima di Pinaderio and the Cima Giu (2,369 m/7,773ft), and Olivone in its fertile valley, with the jagged granite peak of Sosto rearing above it.

Acla (1,476 m/4,843ft: off the road to the right) has an interesting chapel. Leaving Acla, the scenery now becomes wilder; Fumatschfalls, 30 m/98ft high, on the Medelser Rhein. To the rear there is a view of the valley around Platta, with the Tödi massif rearing up beyond the Vorderrhein.

5.5km/3mi beyond Camperio there is a rewarding drive along a road which branches off on the left and after traversing a tunnel 1,490 m/4,889ft long, which bypasses the narrow Gola di Sosto, reaches the mountain village of Campo Blénio (1,228 m/4,029ft), 4.5km/3mi north, situated at the meeting of three valleys. Beyond this, 1.5km/1mi up the Val Camadra, is Ghirone (1,302 m/4,270ft), with a very picturesque old church; then 3km/2mi east up the Val Luzzone to a large artificial lake (1,590 m/5,217ft).

Curaglia (alt. 1,332 m/4,370ft), with a church of 1672 (Late Gothic altar), is situated at the mouth of the Val Plattas, which runs down from Piz Medel (3,210 m/10,532ft: seven hours with guide).

Dongio (470 m/1,542ft) is a long straggling village surrounded by orchards, where the by-road from Aquila comes in. To the southwest, on the other side of the Brenno, stands the chapel of San Reigio, with Romanesque wall-paintings.

Down the valley from Torre, on the hillside to the left, is the village of Lottigna (695 m/2,280ft), the chief place in the Val Blenio, beautifully situated at the foot of Simano (2,580 m/8,465ft), with a church of the 15th and 17th centuries. Beyond this there is a superb view down the valley, with a view of the pyramidal peak of Sosto to the rear. Acquarossa (538 m/1,765ft), is a spa (mineral spring, 25.5 deg C / 78 deg F).

Beekeeping is one of the components in this museum of local rural crafts.

The Lucomagno pass (Romansch Cuolm Lucmagn, German Lukmanierpass: 1,978 m/6,492ft), with an inn, a large stone figure of the Virgin and a chapel, is the lowest road crossing of the central ridge of the Swiss Alps, over which there was already considerable traffic in medieval times. It is flanked on the left by Scopi and on the right by Scai (2,676 m/8,780ft). The pass marks the boundary between the cantons of Grisons and Ticino.

Malvaglia (375 m/1,230ft), lies at the mouth of the deep Malvaglia Valley, with the church of San Martino (originally Romanesque, altered in 1603: beautiful campanile). A narrow mountain road runs 10.5km/7mi up the Val Malvaglia, passing an artificial lake, to Madra (1,086 m/3,563ft).

The main road from Val Luzzone runs down to the village of Olivone (Romansch Uorscha, 893 m/2,930ft), a summer holiday resort beautifully situated at the junction of two arms of the Brenno under the massive pyramid of Sosto (2,221 m/7,278ft), surrounded by fruit trees. It has a fine old house, still inhabited, the Casa Cesare Bolla (ca. 1500), once the residence of the governor, and an interesting local museum (opening hours given). Beyond Olivone the road to Biasca winds its way down the fertile Val Blénio, on the left bank of the Brenno, to the valley floor.

From Pardatsch (or Perdatsch), 1,556 m/5,105ft, a hamlet with a small chapel, the road continues uphill under Piz Curvet (2,248 m/7,376ft) to Sogn Gion (1,615 m/5,299ft), a former hospice. It then climbs a lonely Alpine valley, with tumbles of rock, areas of sparse pasturage and rhododendrons. To the right are the pointed summit of Tgiern Sogn Gion (2,677 m/ 8,783ft) and Piz Ganneretsch (3,040 m/9,974ft).

East of Curaglia there is a rewarding climb (3.5-4 hours) up Piz Mauraun (2,897 m/9,505ft), from Monte Rosa to the Ortles (Ortler) group, and of the nearer Tödi group in the Glarus Alps.

The road descends from the Lucomagno pass through a rocky valley, following the left bank of the Brenno, which is fed by numerous streams flowing down from Scai and Pizzo Lucomagno. To the left are the rock walls of Pizzo Curvo (2,510 m/8,235ft). Then it continues through an area of high Alpine meadows with scattered summer chalets. Ahead can be seen the Rheinwaldhorn (3,406 m/11,175ft). 4.5km/3mi beyond the pass, on the right, is the Aquacalda inn (1,780 m/5,850ft; Albergo del Paso, 20b.), surrounded by a forest of stone pines, with a beautiful waterfall on the Brenno.

Platta (1,380 m/4,528ft) is a straggling village (church with Romanesque tower) in an open part of the Val Medel.

From Sogn Gion the Santa Maria lake (formed by a dam completed in 1967) can be seen below the road on the right. On the old road on the west side of the lake, at Santa Maria (1,842 m/6,044ft), was the old hospice of "Sancta Maria in Luco Magno" which gave its name to the pass. Above the west side of the lake is Piz Rondadura (3,016 m/9,895ft; 3.5 hours), to the east the dark slaty peak of Scopi (3,187 m/10,457ft; 4-4.5 hours).

Torre (770 m/2,526ft) is prettily situated on a terrace, and here a southern vegetation of vines, mulberries and walnut-trees begins to feature more prominently in the landscape.

The road traverses the Alpine meadows of the Piano di Segno, passing above the huts of Campra, continues down the north side of the beautiful Valle Santa Maria, high above the Brenno, and then through a wooded gorge, passes close to the Albergo Grande Venezia and comes to the former hospice of Camperio.
