Don't skip Athens. I know everyone treats it as a layover city on the way to the islands, but it deserves two full days minimum. The Acropolis is as impressive as advertised. The Monastiraki neighborhood is excellent for wandering. The food scene in Psiri is genuinely great.

Stay in Plaka or Monastiraki if you want to walk everywhere. The boutique hotels in these neighborhoods are charming and reasonably priced compared to the islands.

Santorini is worth it — once. The sunsets in Oia are genuinely spectacular. But it's expensive, crowded in July and August, and the beaches are volcanic black sand (not everyone's thing). Go in May or October.

Naxos is my favorite. Bigger than most people expect, with excellent beaches, a charming old town, and a fraction of the Santorini crowds. You can rent a car and drive the whole island in a day.

Paros is a good middle ground — livelier than Naxos, less overwhelming than Santorini. The village of Naoussa is beautiful and has some of the best restaurants in the Cyclades.

Order the grilled octopus everywhere. Fresh feta with everything. The Greek salad is a cliché because it's perfect. Loukoumades (honey donuts) for dessert.

Eat at the tavernas away from the waterfront — the ones with handwritten menus and plastic chairs. They're almost always better and half the price.

July and August are brutally hot and crowded. If you have flexibility, May, June, September and October are dramatically better experiences.

Ferry schedules change. Build buffer days into your itinerary, especially if you're island-hopping. Missing a ferry because you were too tight on time is a very avoidable stress.

La Jolla is my favorite base — beautiful cliffs, great restaurants, walkable, and only 20 minutes from downtown. It's a bit more expensive but worth it for the setting.

Little Italy is excellent if you want to be in the middle of the food and nightlife scene. Walkable to the waterfront, great coffee shops, and some of the best restaurants in the city.

Coronado is worth considering if you want a beach resort feel — the Hotel del Coronado is iconic, and the island has a lovely small-town energy.

The La Jolla Cove is non-negotiable. Walk the cliffs, watch the sea lions, have lunch at one of the restaurants overlooking the water. It's one of the most beautiful spots in California.

Balboa Park is worth a half day — the museums, the gardens, the architecture. The San Diego Museum of Art is genuinely good. The botanical garden is free.

Yes, the San Diego Zoo is excellent. If you have kids or just love animals, it's worth the price. Go early, leave by noon before it gets crowded and hot.

Little Italy has the best restaurant density in the city. Ironside Fish & Oyster for seafood, Juniper & Ivy for a special dinner, Breakfast Republic for the morning.

The fish tacos are a San Diego institution. Rubio's is the famous chain but the best ones are at the small spots in Ocean Beach and Pacific Beach. Order them grilled, not fried.

North Park is worth a dinner trip for the independent restaurant scene — more local, less touristy, excellent cocktail bars.

June Gloom is real. The marine layer keeps mornings overcast in June, sometimes into July. It burns off by noon most days, but if you're going for beach weather, July through October is more reliable.

Parking is annoying in La Jolla and Little Italy. Build in time for it or just use rideshare for evenings out.

Hudson is my top pick for a first visit. It has the best restaurant scene in the valley, a walkable main street (Warren Street) full of antique shops and galleries, and good hotel options. It's also centrally located for day trips.

Rhinebeck is charming and quieter — great for a romantic weekend. The Beekman Arms is the oldest continuously operating inn in America and worth staying at just for the experience.

Woodstock has the most character — artsy, a little eccentric, excellent for browsing. Don't expect the music festival; it was actually held in Bethel, 60 miles away. But the town itself is worth a half day.

Olana State Historic Site is one of the most beautiful places in New York State. The Hudson River School painter Frederic Church designed the house and the landscape himself. The views of the Catskills are extraordinary, especially in fall.

Dia:Beacon is a world-class contemporary art museum in a converted factory on the Hudson River. Even if you're not an art person, the building and the scale of the work are worth the trip.

The farm stands and orchards are part of the experience. Migliorelli Farm in Tivoli, Greig Farm in Red Hook, Fishkill Farms in Dutchess County. Pick your own apples in October — it's a cliché for a reason.

Swoon Kitchenbar in Hudson is my go-to for a proper dinner — farm-to-table, excellent wine list, consistently good. Book ahead on weekends.

The Pines in Hudson for a more casual dinner. Bread and Butter in Rhinebeck for breakfast. The Crimson Sparrow in Hudson for cocktails.

The farmers markets are worth planning around. Hudson Farmers Market on Saturdays, Rhinebeck Farmers Market on Sundays. Buy cheese, bread and fruit and have a picnic somewhere with a view.

Fall weekends book up fast. If you're coming in October, plan at least 6–8 weeks ahead for accommodations. The foliage peaks mid-October and everything fills up.

You really do need a car. The towns are spread out and there's no good public transit between them. The train gets you to Hudson or Rhinebeck from NYC, but you'll be limited without wheels.
