Every Muslim has a dream to visit Macca. Great to hear you want to visit Macca as a destination on your next trip. Now the holy place can be reached by plane, but in the past when there were no planes, people used to walk to Macca for Hajj. One of my grandfathers walked to Macca and performed Hajj. Once you visit the place, you don't want to come back. Although I have not been there yet but I have heard from many people. I also have a dream to go to Macca. Best wishes to you.
