AVOID RIDING THE DONKEYS!
I know I bring this topic up a lot, but we are still in peak tourist season, which means 1000s of new people are visiting Santorini every week and may not know what these animals are going through.
If riding a donkey is on your list of things to do while you're visiting, I would strongly encourage you to reconsider. There are other ways to get where you are going. You can walk. You can take the cable car.
The donkey rides might look like a classic Santorini experience in photos and travel videos, but seeing it in person is very different. These animals spend hours climbing steep steps in the heat while carrying tourists all day long. You don't have to agree with me, but I do think it is worth taking a minute to think about the animal behind the experience before deciding whether to participate.
Skipping a donkey ride won't take anything away from your trip, but it could make a difference for the animals that are still doing this work every day.
