Registering a domain name and arranging hosting for your travel blog is pretty easy, almost the same as booking a plane ticket.
If you just Googled, you can see that there are a lot of parties that can offer this. And some can install WordPress with a single click. Try to make sure your domain name resembles as much as possible the travel blog name you chose.
When blogging in English, try to register a .com domain name. This will help you to be found in Google. And of course that's what you want.
