While the main winding path up Petrin Hill is pleasant enough, serious hikers should explore the steeper trail networks that branch off it. Multiple unmarked routes to top, better elevation gain for urban hike, you'll earn those views.

Start from various park entrances around the base and look for narrower dirt paths that split from the main paved route. Well-worn trails, 25-30 minutes steady climbing if you take the direct routes. Decent shoes needed — Muddy after rain. Best viewpoint areas near the tower where there are clearings with benches. Less crowded than funicular or main path, same views, free.

Trail difficulty: moderate to challenging depending on route choice. Effort-to-reward ratio: excellent.
