Depending on your occupation, you might have a couple of days (or weeks) of holiday during easter. Most would consider staying at home or visiting their family during this time period, but visiting other European Countries is becoming a more and more popular trend for many central Europeans.
Southern European countries offer the perfect climate for walking around and exploring the area without the much dreaded heat, as the mild but warm climate is seen as relaxing by many and does not make you sleepy. Especially if you want to do one of the popular wandering tours along the Alantejo or Algarve coast, the climate is perfect, as it is not too hot, and not too cold.
This is also similar for Spain, as the adjacent country lies in the same climate zone.
