I first played this course when it had 6 baskets back in 2005 and it has gone through some significant changes, each making the course better. All descriptions are for rhbh from long tees with some mention of short tees that I like.
#1 - tight shot to open fairway. Make three for a solid start.
#2 - wide open fairway up a hill to a protected green downhill in the middle of trees in long position.
#3 - tight tunnel with water on left from long pad and short pad is a great short hole hole through tunnel with water behind. Great shot a 2.
#4 - another tunnel shot with water on the left and target protected by trees and another shot a 2.
#5 - Challenging hole uphill and to the left with the first of several chances for major rollaways down the hills
#6 - tight par 4 hyzer to basket on a ledge. Must be accurate with midrange.
#7 - Possibly the most fun shot on the course! 30 foot elevator drop to short pin. Good for a thumber.
#8 - tricky shot with a good chance of going in the creek if not careful. Short, uphill to a target on the right edge of about a 10 foot drop off into the creek. I have noticed over the years there has been significant erosion in this area of the course so the basket seems a little higher than most.
#9 - Great hole! Tight uphill fairway over ridge to basket on the right side.
#10 - Another great uphill shot from the shorts and tight fairway from longs. The route for the long pad is a tight hyzer which could be redesigned a little as the green and target is almost a poke and hope if you go for it on the second shot. The short pad is one of the most fun shots on the property and chance for 2.
#11 - This use to be the signature hole when you threw across the creek but the current target placement is much more challenging. Huge dogleg left with a major downhill shot where it is better to be on the right side of the fairway to have a chance of getting in position to get to the fairway or possibly green for big arms on the 2nd shot. Creek runs down the right side of the fairway but not really in play unless you hit it early or during your approach. You are more likely to get in the creek from a ricochet off one of the many small trees. Great hole!
#12 - Another great tunnel shot with no room for error if you want a deuce. Creek on right is in play off the tee. You can easily take a high # on this hole if you underestimate it.
#13 - Open tee shot into a cluster of trees. Kind of a throw away hole for flow. I think it would be a little more challenging by teeing in the forest through a tunnel to have the basket back to the left.
#14 - Great hole over pond with basket sitting on dam and major drop off. Commit to the shot or you go ob or over the target with a roll away and difficult putt back towards the pond.
#15 - Super challenging hole with creek to left and small gap to hit for a chance at 2. This hole is deceiving as it appears easy but I have seen many 4's due to ob by basket or not getting through the gap leaving a long touch shot for par.
#16 - Throwaway hole for flow but challenging with a slight anhyzer across creek to basket next to creek.
#17 - Great hole with lots of ob. Waste area to the left, creek to the left and behind but great chance at two if you can navigate the small green.
#18 - Major anhyzer from longs (90 degrees from longs). 3's are rare from what I have seen on this as the tee shot must be perfect to open area in fairway well past short pad. Basket up in guarded green.

Erosion has exposed some sleeves which could be filled in.

Images on dgcr do not do this course justice, you need to see it in person for the elevation changes, tight wooded holes, routes and open shots. Play this course with foliage in the summer months for a real challenge. I do miss the long shot across the creek on #11. If I was in the local club, I would purchase another basket to add back up to the right to have 2 targets on the hole for tournament as it really would not affect the current layout. Also, some of the other changes in the past were changed to make the course better (#12 or #13 was once a major hike up the hill and not really fit with the course as it was throw as hard as you can straight until you threw up to a target on a hill. If Greenville, Spartanburg, Clemson, Easley ever bid for Worlds, this course would be a great fit.

Of the courses I've played, this is by far the most scenic.
Well layed out and thought out.
Holes are challenging and well marked.
Some open, long holes and some tight short ones, good mix.
Tees are concrete and well marked.

No established par, leaving the assumption that course par is a 54, despite a few 400+ feet holes.
Could benefit from the placards that are in place at Century Park, showing basket locations and obstacles.
Two swamp areas that come into play on three holes, bring your waders if you throw into there, or at least a change of socks and footwear.

This is my home course as well as being the first course I ever played. There have been some major improvements over the past five months to the grounds and paths (mulch has been laid down on much of the pathways). There was a huge pile of trees and scrap wood when I first began playing this course, but that has been removed and I no longer have to climb thru it to find my disc! Spartanburg Parks and Rec has the upkeep and have done a great job, even being very accomodating to someone who throws very erratically when they are working! Some football/soccer fields and a nice playground for the kids. Of the three area courses I've played, this is the most purpose built for Disc Golf and would be very good as a tournament host.
