I'm planning a hike on the Goldsteig trail. Can you tell me its total length, where it starts, where it splits into the Nordroute and Südroute, and where both routes end? Also, for each of the Nordroute and Südroute, how many stages do they have, and what is a key characteristic that distinguishes them?
Navigate to 'goldsteig-wandern.de'. Click on the 'Routen & Etappen' link in the main navigation (ID 58). Locate the total length of the Goldsteig trail. Identify the starting point of the Goldsteig trail. Determine the point where the trail splits into Nordroute and Südroute. Identify the common end point for both Nordroute and Südroute. Click on the 'Goldsteig-Nordroute: Gipfelroute' link (ID 291). Identify the number of stages for the Nordroute (e.g., N9 to N23) and a key characteristic from its description. Go back to the 'Routen & Etappen' page. Click on the 'Goldsteig-Südroute' link (ID 298). Identify the number of stages for the Südroute (e.g., S8 - S22) and a key characteristic from its description. Synthesize all collected information into a concise answer.
