The 5th is a sporty medium-length par 3. I love how the tee box is simply a continuation of the 4th green complex. It reminds me of rolling out of bed and being right on the first tee. Wait...they have that here at Ballyneal also. This place is a dream come true.
You'll notice in the next four pictures how the hole is dominated by a little, diabolical bunker right in front of the green. It really messes with your head. The left-front quadrant of the green sits high on a ridge. When the pin is left, you're tempted to try to thread one between the small bunker and the left edge of the green. Miss the green left and you're doomed -- whether you reach the large bunker or not. You'll be faced with a high-touch shot up the ridge to a green running away from you. The prudent play off the tee is probably to the middle/back of the green and try for the two-putt par, but what the heck do I know about prudence? Take dead aim!
Right hole locations are far more accessible as both front-right and back-right sit in bowls that allow for shots from multiple directions. I believe the 5th has more aces than all the other par 3's combined.
This is a very good medium par3. As you say, there are some fun putts and easier hole locations on the right side. But the left side can yield some very difficult locations that leave you scratching your head.
