I decided to travel first to Hercules, and from there descend along the winding path beside the cascade to the schloss.To reach Hercules I took tram #3 from Kassel city centre to its terminus at Druseltal, and there transferred to bus #22 whichn ascended to the visitor centre beside the monument.
The base of the monument was shrouded in scaffolding, as was the upper terrace, which detracted from the view.
From the schloss I descended to another visitor centre and the terminus of tram #1 for the return to the city.
