Volcano Gravel Day is a full day on unpaved tracks near Leon, covering 88 km with 1,600 m of climbing. The route links the extinct volcanoes with long stretches of beech forest, so the day alternates between open, rounded volcanic terrain and shaded woodland tracks.
It is a hard day. The climbing is steady and repeated rather than concentrated in one big pass, and the surface asks for attention on loose and rutted sections. You should arrive comfortable with several hours on gravel and with a bike that handles it well.
Among the Ride Leon tours, this is the most demanding gravel option. It has noticeably more climbing than the Forest Gravel Loop near Leon at 72 km, and it is far harder than the Riverside Gravel Intro. It is also a scenery-led day, unlike The Big Climb Morning, which is built around a single serious ascent.
