Will be in the CT for 3 nights, staying in Monterosso al Mare. One day we are planning to hike as much of the trail as we can (from Monterosso to Riomagiorre) and then take a boat back to Monterosso. The next day we are going to relax on Monterosso's sandy beaches in a lounge chair (as a vacation from our vacation).
My question is, is it worth our time to take the boat from Riomaggiore out to Portovenere before heading back to Monterroso? I understand it's only accessible by boat? Would appreciate comments from anyone who's been there and has opinions about it. If we do go, how much time should I devote to the town?
