5. San Diego, California
Things to do: Experience The Gondola Company, La Jolla Kayak, explore Coronado Municipal Beach
I think this one would really make Greg feel inadequate. This is one of the most visited cities in California, primarily because of its beautiful beaches. Sometimes a weekend trip is best spent laying on the beach and taking a nap. For adventure, La Jolla Kayak is a great option. If you want to feel like you went to Italy instead of staying domestic, take a romantic gondola ride in Balboa Park. There’s amazing food there as well, which all makes it one of the best places to visit in the USA for couples for a weekend.
