Excellent fast and steep run, the walkin is rewarded.
Putin · Takeout
Turn off the A55 at Abergwyngregyn and follow signs for Aber Falls. At the carpark head left up a small steep road to another small carpark. This is the takeout: the putin is a strenuous but rewarding walkin continuing up along the track out from the carpark.
Rainchasers is best experienced as an app.
