To see the Cinque Terre in 2 days, stay in Levanto or La Spezia for easy train access. Day 1: Buy a "Cinque Terre Treno MS Card" for unlimited train travel. Start in Riomaggiore (the southernmost village), then take the 2-minute train to Manarola for a scenic lunch at Nessun Dorma. Finish the day in Vernazza, exploring the harbor and staying for sunset. Day 2: Start in Corniglia (the quietest village, located on a cliff), then take the train to Monterosso al Mare. Spend your afternoon on the beach (the only large sandy one in the region) or take a boat tour to see the colorful villages from the water. If you're a hiker, use Day 2 to walk the "Blue Trail" between Monterosso and Vernazza (about 2 hours) for the most iconic views of the coast before heading back.
