I have heard that the hiking from Monterosso to Vernazza is very steep. How steep? and what is the footing like? Gravelly? Slippery? How wide is the trail? Is there anything to hold onto? Will I be going up or coming down? I'm in my mid-60's and will be travelling with my husband. We work out and are both in fairly good shape, but I don't like the idea of sliding off the trail and plunging into the abyss. I really would like to hike this trail, since we are staying in Monterosso and could begin early in the morning.
