Pros:
Navigation: Great course map, every tee pad has a tee sign, each basket has an arrow to the next tee, if there is a long walk, there are red marks on the ground showing the path.
Elevation: lots of it. Several holes throwing down big hills, one across a valley (#9), one on top of a ridge line (#4), a few going up hill.
Nice layout: good use of terrain, hillsides, curves, trees for the basket and tee locations to create some nice holes.
Clubhouse and communication: The clubhouse is open from 11.00-17.00. They have maps, discs for rental or sale, a log of record rounds from each country, who has gotten aces on which holes, and is staffed by some wonderful folk. I was in the area outside of the open time, but I communicated with the clubhouse via Facebook and was able to get out and play before things opened, and pay for my round after (10 euro). They were also wonderful to talk to after my round to hear about the course and clubhouse history.
Views: Wow. Check it out.
Cons:
Several of the tee pads are rough enough to trip on - rocks coming through (looking at you #6).
Several of the paths between holes are on steeper rocky slopes that can be tricky to navigate (like off of #4 basket). They could use a small stair case or a few logs across the path to help bench the slope.
Many holes have big thorny bushes where discs can go missing. Keep your eyes open!
Other Thoughts:
Roll aways are very possible on several holes. A small net or log/small fence halfway down the hill could really help for some people who have all the bad luck while not taking away from the punishment of missing a putt.
Two holes (#11 and #12) just feel a little forced. They add a different dynamic rather than grip it and rip it, but they just don't match the feel of the course.
All this being said, I'm easily comparing this to any top rated course in the US or Scandinavia, and it is located in Spain! Fantastic to see the sport growing here. Keep it up!
