I'm pretty new to the sport and have realized that there is a solid dg following from MN to MI and IN to IA. Obviously the west coast has a lot of players and the south east as well. But where would you consider the disc golf "Mecca" or "Meccas" of the world?
So many variables to this question, some to most have already been mentioned in other posts, but lets throw out the mid-Minnesota perspective.
With a group of friends -
Highbridge hands-down. Five difficult courses that are incredibly fun to play with a group of friends that are competitive enough to make you want to do well on incredibly difficult courses, but can have fun when those shots ultimately destroy your score. You will be greatly disappointed if you go alone and or immediately following the InfraSound concert, so it is more about the experiences with friends on what could be great courses.
A group of courses that has it all in terms challenges -
Kalamazoo, especially Am Worlds layout. Minnesota lacks technical elevation. Kalamazoo has it in abundance.
Centralized big courses in an urban (and thus ease of transportation) setting - I really enjoyed the courses in and around
Des Moines. Being from Minnesota, I would like to say east and south-east Twin Cities with courses like Lakewood, Kaposia, The Valley, and Oakwood, but the Des Moines courses, at least when I was last there, where in better shape, better spread out over their metro area, and for the most part more challenging. The Twin Cities would be rated higher if there were more permanent and more challenging courses in the western suburbs. We (as I used to live there until recently) have Bryant, Elm Creek, and HSSA for 18s, but all are seasonal and designed to be appealing to beginning players as they are run by the Three Rivers Park District. Crown is the only permanent one, and while a fun course, is not overly difficult and is still quite a drive to be considered a Twin Cities course. There are a ton of 9 to 12 hole courses in the western Suburbs, but they are often packed, in poor repair, and only have a handful of difficult or marquee holes.
Destinations for uniqueness and experiences - This one I am going to falter on because of my limited travels, but from pictures and stories from others, I have heard go things about the courses in
Montana, Alaska, Hawaii, and Colorado. As for non-US locations, I have also heard great things about the courses in
Sweden and
Germany. I am sure there are great courses all over the world, but some of the pictures I have seen from these two countries are nothing short of breathtaking.
