Hi, I hope this isn't off topic, but you could even hire a three wheeler
from the shops opposite the station. at some points along the way you have to get off for a short distance as the climb is too steep for a fully laden 3w, but its another available option if you miss the van.
also makes for quite an adventurous ride up to the plains
you could walk
it as well, but make sure to pack light! our first time we packed everything but the kitchen sink and paid for it with a 5 hour relentless climb up the steep hills carrying the weight.
It is a beautiful walk though and don't count it out if you are fit and prepared. take plenty of water as i can't remember any obvious sources along the walk.
