I climbed it!--in the early spring, not too green, not too cold but some light hail and need for a sweater. I had a great friend who walked me through the majority of the park, my legs were worn out the next day but this is certainly a highlight of the trip. There is a panoramic view of the city from one viewpoint, great running/walking/biking paths, some lakes (artificial), lodges that feel like ski lodges, a religious view from the large cross which can be seen from above. Not too many cities have an adjacent natural perch that is taller than most of the buildings, this is a natural treat for the city.
