Both paths are extremely scenic. SPP runs almost entirely through panoramic terrain, the path through the Reka gorge a bit less, but I think it's more scenic than SPP - you see more of nature's forces at work... If you choose SPP you'll have to hike one section twice, namely below the village Gradišče there's a branch for Divača direction and you'll have to return from Škocjan Caves to that junction to continue to Divača. If you choose the path through the Reka gorge, you never go twice over the same section... Nice to hike both paths, especially in spring... Happy hiking!
