Where to visit in March?

You really only have 2 choices for this time of year ... spain or SPAIN !!

If you don't want to be cold then Greece, Italy, Portugal, Spain (as it was already suggested). I know you asked about cities not countries. So Athens, Rome, Naples, Lisbon, Barcelona, etc.

We usually go the last few days of March--the end of the Winter airfares. The first 2 weeks of April, the weather's changing in middle Europe.

You can tell because the manure piles have thawed and farmers in Italy, Austria and many other countries are spreading it on their fields.
We prefer the Austrian Alps over Switzerland as roads are easy to travel and it's so much cheaper of a place to visit. And the mountains are also absolutely breathtaking. Northern Italy's also a great place to go that time of the year.

There are websites that give weather averages, and since you're going in March, you may want to study average weather. Of course, averages are only averages and the actual weather will likely be different, but you need an idea of probable weather in areas you're considering.
You asked about the weather in Switzerland in March--that depends very much on the elevations you're planning to visit.

March is still the ski season in the Swiss Alps. Great if you ski, not so great if you have in mind summer hiking activities.

Valencia has their fire festival during the end of March. I'd check that out, then head to southern Spain.

If you've been there many times, how about opening it up a little?
Greece and Spain would be good, of course, but why not Cyprus, or southern Turkey? You won't see any Americans at either of the last two, I wouldn't think.

Spain!!

March 15-19 is the Fire Festival (Las Fallas) in Valencia. Semana Santa begins on March 20 (Palm Sunday). The biggest celebrations are in Malaga and Seville. It can be very exciting to be part of any of the festivities, but it will be super crowded.

There are other wonderful places to visit in Andalusia if you want to avoid the crowds.

I don't know what goes on in Portugal during Holy Week but friends were there last year in mid-March (well before Easter) and came back raving about how wonderful it was.

Yes, Melbourne is nice and full of very friendly people but Sydney that's San Francisco of Australia.

Um, no, Sydney is the Sydney of Australia

I like the ideas of finding festivals or special reasons to be someplace. When possible we plan trips around special events.

March 15th is a national holiday in Hungary. It stands for democracy and freedom and it commemorates the Hungarian Revolution of 1848, which grew into a war for independence from Habsburg rule.

In practical tourist terms it means parades, soldiers on horseback in 19th century Hussar uniforms, street vendors with food and local crafts, lights and celebrations. One of the most festive days of the year. We've done it a few times and have always been blessed with cool temperatures and vivid blue skies. One of my favorite times of the year to be in Budapest.

Texas? You mean Paradise? Absolutely!!!!!
