Free or reduced admission at the beginning and end of the season (depending on flowering).
Guided tours are led by botany students from the University of Grenoble. Their knowledge will enrich your visit and provide interesting information about the microclimate of Lautaret, allowing species from afar to flourish up there. They will answer your questions with pleasure. Do not miss !
