My favourite riding is on trails with heavy tree cover. I also prefer a heavily ridden trail beaten & worn.
My local riding is Rocky, wet & muddy with mud holes & river crossings through beautiful wooded mountains & swampland. There is one mud hole so hairy that it earned the name Scouts Hole because it supposedly ate a Boy Scout. I can drive from Vermont to Massachusetts on those trails.
I also Love riding at my friends camp named Widstock. We have been cutting and trimming trails there for 18 years! It's similar to my local riding but with a minimal amount of rocks & more off camber and uneven riding, a nice challenge. It also has a mud hole named The Bog.
Starting thirty years ago I used to ride in The Pine Barrens of NJ. There are mostly what NJ people call scrubby pines (man sized pine trees) & lots of sandy trails. The sand is loose in some areas and packed in others. Once while riding on 2 Honda ATC 250SX 3 wheelers, my 1985 & my buddy Joe's 86 we came up to the west side of the Garden State Parkway. I didn't hesitate and rode out onto the shoulder of The GSP. I rode next to the vehicle traffic as quickly as possible and got back onto the trails just as quickly! Great fun in the Pine Barrens!
