Travel after you have retired is clearly one of the most popular and desired pursuits for this phase of life, whether it be day trips by car, cruising the islands or winging across the other world to see family.
Travel does not need to be expensive. In fact, if you are thinking of travelling overseas for a while, you could Airbnb your house! Also, what about a house swap with someone from another country, or even housesitting? You may even have an Aunty Mary overseas who would just love a visit.
There are tours like Intrepid Travels, which have last-minute deals if you are not averse to a few quickfire decisions. While last-minute travel decisions can be exciting, this can rob you of all that fun trip planning, so keep that in mind.
One of the ideas that you can consider is volunteer programmes abroad.
If overseas travel is not for you, why not a road trip? I have only ever done one road trip that I went on with a friend. No destination in mind, just drove and pulled over whenever we felt like it, no accommodation booked. It was great! What an adventure we had.
