According to Age UK, older people travel more than any other age group. There are plenty of websites and travel agencies offering holidays for seniors, and there are others specialising in Israel trips or Jewish interest holidays, so we won't reinvent the wheel. If that's what you're looking for, it's best to put the search term relevant to you into Google in order to begin your travel quest.
And don't be at all worried if you want to strike out on your own! When talking to your travel agent, ask for options that have activities designed for solo tourists. Whether it's a cruise or a vacation package, exploring on your own is a great way to meet other people who share your passion for seeing new places.
Here are some helpful resources about travel for older people to get you started.
