The Biancane Geothermal Nature Park is an extraordinary protected area located in the municipality of Monterotondo Marittimo, in the province of Grosseto. This place owes its name to the characteristic pure white color of the rocks, chemically modified by volcanic emissions and acidic vapors that transform limestone into gypsum. The park offers a suggestive journey into the geothermal manifestations of Tuscany, including: Soffioni and fumaroles: Cracks in the ground from which water vapor emerges at high temperatures (around 100 °C). Putizze and thermal springs: Pools of boiling mud and emissions of hydrogen sulfide that give off the classic smell of sulfur. Lunar landscape: The combination of bleached rocks, reddish colors due to iron oxidation, and perennial steam creates a unique atmosphere in the world. Access to the park is generally free and it is equipped with paths and walkways to walk safely among the steam vents.

The Bruna is a river approximately 42 km long that flows in the northern part of the province of Grosseto. The watercourse has its sources in the Colline Metallifere, just south of Massa Marittima. Initially flowing east, it forms the Accesa Lake, then receives a couple of left tributaries and finally makes a bend to the right, deviating its direction south and entering the northern Grosseto plain near the villages of Castellaccia and Giuncarico in the municipality of Gavorrano. After a few kilometers, after passing the town of Macchiascandona, it curves right again, heading southwest near the Ponti di Badia, and crosses the entire Diaccia Botrona until reaching the town of Castiglione della Pescaia, where, passing under the Giorgini Bridge, it flows into the Tyrrhenian Sea.
