Bro I will suggest you to go for the canon EOS 200D with that you should buy a 50mm lens and other accessories . If you want a better than you can also buy a action camera with that camera to capture some amazing moment (underwater).
More than camera the most important thing in photography is Camera + Lens. Remember you can't do much even if you have best camera with you. You need the best lens for your uses. So you should buy DSLR with travel purpose lens only. Many people don;t know much about camera and their equipment. Almost every camera comes with 18-55mm and another zoom lens like 55-300 or 55-250mm lens. But you won't get quality what you think before buying. So do little research about lens too for best results for your pictures. For travel photography only I recommend you CANON 80D with 18-135mm lens. This lens gives much better quality than basic or dual lens which you get on any camera. Also you won't need to change any lens for multiple times bcoz this single lens is enough for travel photography. Still research by your own and take decision don't go with anyones opinion or review
Canon 80D with Lens type differs from what type of photography you a aiming to do is best option but personally I suggest to go for sony alpha series (Sony alpha6400 or Sony alpha6500) with lens setup it will slight on expensive side but it is compact and easy to use and more importantly its sony's latest mirror less technology with built in image stabilizer makes things easy for on the go shooting.
