the best advice I think is just to chill. If they need something, they'll ask. Don't go out of your way to treat them differently.

Hey awesome that you are asking. I think the most important thing is always treating someone like you would treat anyone else of course. My partner is visually impaired and needed help getting familiar with her university campus so that's great you are doing that. Definitely letting him be aware of what exists resources wise/tech wise/opportunities in general. My partner was very shy and had a hard time asking for help in general so she credits a few people who really made the effort to let her know what options exist. :D Most importantly I think including everything is crucial for our world. I recently found a board game FOR visually impaired people (well it was developed by an awesome woman who wanted to include a visually impaired family member- so its for sighted and non-sighted) called Nyctophobia that might be fun to play on campus if you want. I'd say 3 people at least. There needs to be a host who can see and facilitate though- it offers others a chance to empathize and understand how to operate without vision (the players wear glasses that prevent you from seeing the board so you have to FEEL the board and communicate with others players). My partner loves it because its her comfort zone- not being able to see. To have everyone on the same page makes her giddy and stoked. Often visually impaired folks are not able to participate in all games because they tend to be visually dependent. There are tons of options though this is just one recent fun one. Definitely be a friend :)

Be a friend and be considerate. And ask him if he has the accommodations he needs. Try out $1 as a tool for location tracking with your phones.

Best advice I can give you really is ...ask them :)

This individual will know best how you can help them best, and none of our recommendations are going to be as accurate as their own.

Be a friend first. He can find people who are , as you said, are REQUIRED to aid him. You can require someone to be your friend.
Although I commend you for looking to this group for information, ask him. You are missing the opportunity to have conversations where he can contribute to information that he knows and you want to know.
Never miss the ooertunity to pick on him. That’s what real friend do. If he get up and trips over something, assuming he didn’t hurt himself, just laugh and say something like”Hey dumb ass, did you ever learn to use a cane?”
Let him help you, be honest, if you are sad or have a problem ask him what he thinks. If nothing else we are good listeners. And most of us have spent a lifetime using context reframing or inventive work arounds to smooth over the bumps in life that we all go through.
Thank you for being a friend!

Most important when figuring out how to help: ask, don’t assume. Sight loss is different for everyone, so what help me might not help them. But they are the expert on their own vision, what helps them and what doesn’t. And if they say they don’t need help, listen to that, too. I have people insist they must help me, instead of listening when I say I’m good. It’s awkward, and sometimes the help they want to give is not actually as helpful as they think it is. So, ask, and then help them out the way they want to be helped.

Otherwise, just be a friend. Treat them like you treat your other friends. Don’t make a big deal out of their blindness. Do things together and talk about stuff that isn’t their eyes.

What everyone else has already said here is absolutely true! I want to add something though. You mentioned the town you live in is not very blind friendly, so something practical you may do that would really help him just to even feel more independent is that if you could ever offer to help him run any errands that he may need in the town. For example, I also lived in a university town that was not always very blind friendly, and I always really appreciated it when friends offered to help me go pick up groceries or small tasks I might occasionally need. I didn’t always take people up on their offers, but just knowing that I would not be inconveniencing someone and that the help was available if I needed it was a huge blessing and took a big burden off of me!
