Pros:
This is a well thought out course. There are mostly elevation shots with many obstacles that are quite challenging.
If you are able to get it worked out with your schedule and Mark's then you'll get a personalized round with the course designer in his 13.2 acre backyard.
There are 9 tees but the 18 baskets are well placed so that you're really playing two different rounds, especially if you use the long tees. By looking at the hole lengths at the bottom of this review you can see how much longer the second nine is.
On the first hole you are throwing down hill into a horse coral that has two baskets in it. The first basket is 275' and the second basket for #10 is 300' but if you land outside the coral you must drop into the corner of the coral and take a penalty.
All tees are numbered and since you'll most likely be playing with Mark he explains every hole in detail. For example, on #8 you can't see a ravine from the tee that is off to the left, but he warns you to stay away from it. I still ended up in the ravine.
The course is not crowded because you are scheduling your round ahead of time with Mark.
Cons:
It's way off the beaten path to get to this place, but it's right next to the Hellhole Canyon Preserve, which is beautiful. That's where the name of the course, The Gates of Hell, came from.
It's great to play with Mark, the course designer, but it also limits the time you can go there.
There is currently no course map to look at, but it's not a big deal if you're with Mark since he explains better than a map can.
Other Thoughts:
Mark hosts a tournament on July 1st that is limited to 27 entrants. You can sign up soon on his Facebook page, "The Gates of Hell Disc Golf Course" for $30. This will be his third year for the event.
Only 12 people, as of today, have recorded on this site that they played there. Mark said he's had about 300 visitors play his course since he put it in 1.5 years ago.
You can see a satellite view of the course from his Facebook page.
Mark is an active member of the San Diego Aces Disc Golf Club and hosts a two day match play in December with different skill levels.
