I think it depends on "level of blindness". Definition of blindness varies even between countries, there are "
$1" people with some vision left, some people are having tunnel vision but perfect sharp and are considered blind too, some are fully blind and I think the experience and enjoyment of travel would weary a lot too if the person has those problems since birth or not.
My grandfather, fully blind since age of 3, was enjoying travel with his wife fully sighted person as long as they health allowed them they traveled with buses and trains, then with organized locals travels clubs for seniors. They visited multiple times european countries and taken photos Italy, Belgium, France and their homecountry. They were swimming, eating local food, visiting famous places like other tourists my grandmother was describing to my grandfather the surroundings was his personal audioguide, always buying some little souvenirs for family. Can't ask for details sadly anymore she passed unexpected in April they're laying together now in the same place. She was so kind soul never complained as well as he only when really hurted miss them so much.
I'm one of legally blind with rest vision 20/1000 with tunnel vision in one eye other one without light perception since 15 yrs. I can still see lots of colors not all of them, I use white cane. I love to travel, its convenient to take someone with better vision so I take my parents we split the costs. They're my sighted personal guides/audioguides/photographers and I am travel organizator/translator/personal expert of modern technology for them because they don't know English. We do everything as typical tourists do: swimming, local places and attractions (searching and booking with internet first), taking photos. My personal favourite: "watching" wild dolphins boat tours (just searching and then hearing them in water in their natural home enviorement so exciting and sometimes they come very close), drinking juice from local fresh pressed fruits. We are traveling with car, train, plane… technology nowadays is very helpful. Lots of apps with OCR technology are must have for travelers + Google Translate. Lots of airports are having assistance service but its often used and needed to be booked much earlier if its busy day you will have to wait a bit or it can be even unavailable due to high demand because its not "high priority" service often.
