In contrast, the southern half is more barren and exposed, often featuring rockier or more open paths. This transition means hikers should be prepared for different underfoot conditions, from shaded forest trails to sun-exposed, potentially rugged sections. Overall, the summit is categorized as an intermediate difficulty, requiring appropriate footwear and a moderate fitness level.
