Pelpi is known for its crystal clear spring water which has an alkaline-sulphurous quality and is renowned for its healing properties. There are many streams that run through the slopes of the mountain, and the mineral water which flows from the north-western slope is bottled in plants at Masanti. The beneficial qualities of these waters were quoted by the early 19th century travel writer Captain Antonio Boccia as commended for curing many ills of those who bathe in its waters. The Milanese poet Francesco Piccinelli also wrote in his description of the Taro and Ceno Valleys (1617) drinking the water, heals all conditions of the throat. During 2009 there was a dispute between a committee of locals and the mineral water company Lynx/Norda, who were concerned that the company would drain the aquifers within the mountain causing the supply to run dry for the personal consumption of the Masanti residents. Every year in mid-August there is an organised hike up Monte Pelpi, as part of the festa di San Gioacchino (festival dedicated to Saint Joachim,) held in the nearby rural village of Cavignaga.
