The air at Ledro is already, after the mountains, soft and warm, and the 2,000 feet of descent to Riva are a surprise. The road runs near the torrent through a narrow glen, between vineyards, mulberries, fig-orchards, and villages, in September a very Alcinous' garden of ripeness.
Suddenly the verdure ceases on the brink of the great mural precipice which overhangs the upper end of Lago di Garda. After several zigzags the road boldly turns on to the face of the rock. The descent to Riva is henceforth a mere groove blasted out of a smooth perpendicular cliff. Deep below lie the dark waters, flecked by white birdlike sails flying southwards before the morning breeze; opposite is the broad crest of Monte Baldo rising above an olive-fringed shore. The horses trot swiftly in and out of the tunnels and round the slow bullock-waggons creaking heavily up to the hills. Riva bursts suddenly into view, a line of bright-coloured houses and mediæval towers crowded in between the lake, red cactus-spotted cliffs, and a wealth of olive-gardens, orchards and cane-brakes—the most southern scene north of Naples.
But before the latter half of September Riva is too hot to linger in. Delicious as is an evening spent in the inn garden, where supper is served under a trellis overlooking the moonlit lake, it scarcely makes up the second time for a night spent in vain resistance to the assaults of mosquitoes. It is best to return to the mountains which are still so near at hand.
The river, which here enters the lake, will be our guide back to the snows. No stream in Europe can boast a more varied or splendid youth than the unknown Sarca, famous in its smooth-flowing old age, when it issues again from Lago di Garda, under the new name of Mincio. It is only necessary to look for a moment at the map to see what vicissitudes the Sarca encounters, and what struggles it has to go through. One is tempted to imagine that after Nature had once settled the Alpine streams of this region in their proper and comfortable beds she gave the whole country a rough squeeze, heaving up a hill here, making a huge split there, and turning everything topsy-turvy. The Adige has, I fancy, been cheated somehow out of the Lago di Garda. The Sarca clearly ought to have joined the Chiese, and flowed down into Lago d'Idro. There is something very unnatural about the eastward reach from Tione, even before one knows how prodigious a feat in hill-splitting it really is.[38]
Thanks, however, to its singular course, the scenery along the banks of the Sarca is extraordinarily varied. Roughly speaking, the river's progress may be divided into four great stages. The first, beginning from the lake, is the Val del Lago, the deep trench which forms the continuation of the Garda basin. Two or three miles through high-walled gardens and vineyards which recall the environs of an eastern city bring us to Arco, lying under a huge castled crag. After leaving behind the broad streets and cypress avenues of the hot-looking town, the drive grows monotonous. The road stretches on through the half-desolate, half-luxuriant valley, from time to time the wheels rattle over pavement, and we pass through the long, gloomy street of some roadside village. The trough is now a wilderness of fallen blocks, the road crosses a bridge, and winds along under great cliffs, which threaten further destruction. Alle Sarche, a wayside inn where the road from the Giudicaria joins that from Riva to Trent, is the end of the first stage in our journey.
The valley continues in a straight line, but our river suddenly bursts out of a deep narrow cleft in the wall of rock which has so long overhung us.
The road first climbs the cliff-face by two long zigzags, then a terrace cut in a bare bold wall of yellow rock pierces the jaws of the defile. High up on the opposite cliff runs the thin track from Molveno to Castel Toblino. The Sarca, victorious over all obstructions, glides along its narrow bed swiftly, yet smoothly, that Mr. Macgregor, or some one accustomed to those fearful feats in a 'cañon' pictorially recorded in books of North American travel, might find it possible to shoot the defile. When the walls break back a rich valley opens round us. The red crags of the Brenta chain glow for a moment in the north, then the Baths of Comano, a health-resort of local celebrity, is passed, and Stenico and its castle are seen on the right, high-perched on a green brow, holding the keys of the upper valley. The road and the river force their way side by side through an extraordinary cleft, split or cut through the heart of a chain rising on either side 6,000 feet above the gulf. The gorge is greener and less savage than the last, yet on a still more magnificent scale. Slender streams fall in glittering showers from the shelves above, and are carried under or over the road by ingeniously-contrived shafts or galleries.
The rocks at length withdraw, the hills open, and while we ascend gently amongst orchards and rich fields of Indian corn, the Carè Alto suddenly raises his icy horn over the green lower range. We are close to Tione, and at another of the great turning-points in the Sarca valley.
Tione itself is a thoroughly Italian country town, with dark narrow streets crossed by archways, large houses built round courtyards, low-roofed cafés, and miscellaneous shops. A happy sign of the times may be seen in the conversion of the large barrack outside the town into an elementary school.
Here we are but a short distance from Pieve di Buono, and a two hours' drive would complete the circle. The valleys of the Sarca and Chiese are at this point separated only by a low grassy ridge over which runs a fine high-road, defended, like every road in this country, by a chain of forts, the scene of some of the desultory skirmishes of 1866.
