The stage from Betanzos to Hospital de Bruma is a long and testing one (30km), including with a stiff climb out of Betanzos. Following the waymarks onto the new route which avoids the steep hill, I was not disappointed, and would follow the new route again. It is an achievement by itself to walk all the way from Betanzos to Bruma in one day, and I did not need the additional achievement of walking up another steep hill situated, remember, right at the end.
The new route walks down a main road for about 2km once it joins up with the path from La Coruna, but there is ample space on the side of the road to avoid the traffic.
