No special access issues
Don't park at the boating club parking site! There's plenty of space elsewhere. Park at the marked parking spots to avoid problems. The approach to the crag is short, so it's impossible to get lost.
Accessing the crag by public transport is difficult. The closest stop is 2.2 km north at the crossroads between Maanpääntie and Härmäläntie. The public transportation goes to the stop only on weekdays, at least at the time of making this topo.
As the Härmälä gorge is a relatively known tourist spot, it sees a lot of non-clinber visitors. Be kind and share space with others!
