"Well, it would make things very difficult if you could not. Ahem. As to geography... This is the Faron region, the southern coast. The sea is calm and there is good fishing. A little bit inland is dense jungle - off the main paths there are many monsters, unfortunately. North of here is the Necluda region, holding many settlements. The most notable of those are Hateno Town and Kakariko Village. I would not be surprised if someone told me Hateno Town was the largest single group of people in Hyrule, though I do not know it for fact. It's a peaceful and prospering place, the Necluda. I would advise against trying to go directly north, however. The terrain is difficult and strong monsters are common. Sailing around the corner of the coast and north may work, but I recommend following the trails inland and crossing the great bridge over Lake Hylia, then heading through the Dueling Peaks. Bands of soldiers and adventurers try to keep the roads clear most of the time, and the Dueling Peaks pass is an important one, so it's usually safe. The Necluda also holds a sacred mountain, Mount Lanayru."
"North of that is Zora's Domain. It's a beautiful city carved of blue stone in a large lake. The Zora are an aquatic people, excellent at swimming, so they made their home in that region of lakes and swamps. Further north yet are the Akkala and Eldin regions. Gorons live in Eldin, near the volcano, Death Mountain. They can withstand the heat natively, but any other visitors need magic to sustain them. Akkala is difficult terrain, sparsely populated, and rather infested with monsters. Far to the west of here are the Gerudo Highlands, a tall series of mountains, and the Gerudo Desert, where the Gerudo people live. There is only one easy passage through the highlands, and soldiers there earn their living by guiding people through and defending against monsters. There is a thriving trade post a few miles outside of Gerudo Town, but the settlement itself admits only women - and they're very strict about that law."
"In the central region of Hyrule is the dark castle. Do not go there. It is very dangerous. You will probably die if you do. The open plains south of it are also tempting. It's good, fertile, beautiful land... But the dangerous monsters called Guardians roam freely there. Mostly, only adventurers and scavengers go there. Far north-east of here, as I said, is the Tabantha and Hebra regions, where we Rito live. It's cold and mountainous, but I think, beautiful. The stables and trails go as far as Rito Village, but not into the Hebra Mountains. Following the trails and staying at stables will usually be the safest way to go somewhere, if not the quickest - though I confess I'm not sure how long it takes for you ground-bound folk to get places." He ruffles his wings. "Ahem. That was a bit of a speech, wasn't it? Any questions?"
