Grigna
[3] The Grigna Massif is located in the central Italian Alps on the eastern side of Lake Como in the province of Lecco, Lombardy.The northern side of the mountain, which is known for its many caves and crevices, leads to Passo del Cainallo and the town of Esino Lario.[4] Among the floristic rarities of the park are the Rhaetian Centaurea (Centaurea rhaetica), the Aquilegia of Einsele (Aquilegia einseleana), Campanula of Bertola (Campanula bertolae), the yellow colombine (Corydalis lutea), the Radicchiella of Froelich (Crepis froelichiana), the Citiso insubrico (Cytisus emeriflorus), the Euphorbia insubrica (Euphorbia variabilis), the Festuca ticinese (Festuca ticinesi), the Ambretta sudalpina (Knautia transalpina), the Laserpizio insubrico (Laserpitidumniti), the Insubric dandelion (Leontodon incanus), tufted horned rampion (Physoplexis comosa), Saxifraga retica (Saxifraga hostii), Tlaspi with round leaves (Thlaspi rotundifolium), Carice subalpina (Carex austroalpina) and Carice del Monte Baldo (Carex baldensis).[7] The mountain's relative isolation affords it panoramic views of Alps toward the north and on clear days, the Milan cathedral can be seen to the southwest.Every year in September, Grigna hosts a Skyrunning event known as the "Trofeo Scaccabarozzi", which starts and finishes in Pasturo.
