We LOVED Cinque Terre and if you can fit it into your travel plans, we’d highly recommend it! 2 days or more would be ideal but if you can only swing a day-trip based on timing, DO IT and utilize the boat tour to maximize what you’re able to efficiently see. It’s such a unique place and provided a totally different aspect to the trip. It’s lush, scenic, and relaxed. We’re also huge pesto fans so it was really cool to explore the region it originated in!
