I own rivierabike based on the western side of Liguria.. there is loads of riding available.
For accommodation hotel medusa as mentioned is right on the beach and Florenz is 1km inland in finalborgo a lovely walled mediaval village. Both are part of the Italy bike Hotels and have access to guides and have bike storage etc… florenz is owned by the president of the 24hr race..
for guides and shuttles contact finalefreeride.com or elicaride.com. In fnalborgo there is a bikeshop rivieraoutdoor.com they can also help with guides etc..
Also pick up the local 1:25000 map there are waymarked routes above the sea (Noli, Orco, Le manie, Varigotti) and it is possible to ride up to the Nato base if you have the lungs and do some of the rides…
As mentioned also contact Fulvio at alpidelmarefreeride.com for some riding in Calizzano faster better and not blown out like some of the finale trails…
Florenz should be able to help with airport transfers…Genova is about 30mins away… but ryanair are ba********
