No special access issues
Accessing Haukilahti provides no difficulties.
Accessing the crag by public transport is easy, as multiple bus lines stop near. Here are a few examples:
105: Mankkaa - Niittykumpu - Lauttasaari
111: Otaniemi - Tapiola - Matinkylä
114: Leppävaara - Niittykumpu - Matinkylä
510: Herttoniemi - Tapiola - Espoonlahti - Kivenlahti
111's and 114's bus stops are the nearest to the crag, but the walk from 105 / 510 isn't bad either.
Accessing Haukilahti by car isn't bad either. Currently the best spot to park your car is near the water tower. The parking spot is marked on the map.
Walking to the crag from parking / bus stops is quite easy, as the paths to the sectors are nice and well trodden. Just follow the GPS trails!
