I wouldn't have thought that daunting is what most short par 4's are aiming for. I would think a good short par 4 should aim for tantalising.
To keep Tommy happy I have done 20 or 30 minutes research and will suggest a group of short 4's that I have found interesting.
Port Fairy 13th 276m. Almost drivaeable but with a severe drop to the left and two reasonably deep bunkers if you attack the green. The green is driveable but if the drive or approach is left it will not hold. Coming after one of the most scenic 5's and before a very good longish 4 and great 3. The 13th is part of a stretch of holes that are hard to match.
Kingston Heath 3rd 269m. Very driveable par 4 but trouble provided by the Heath's renowned bunkering. Only a very well judged drive grants a good angle for the approach to the green.
Kingsbarns 6th Driveable 318 - 337yds. Make a decision on the tee go for the very narrown gap to the green or lay up sort and left. The lay up provides a worse angle to attack the green from.
County Louth Baltray 14th 322-332yds. Turn at the Northern end of the course and survey a green well protected by rough ground.
Brora 12th 314 -362yds. Protected by bunkers in the landing zone. One of Broras many good short 4's
Royal Dornoch 1st, 5th and 15th all deserve mention. Rich can tell you about 1 and 15. The 5th is a delghtful hole from a high tee avoid the many waiting bunkers from between 317-354yds. Going for the green is a very risky option.
The Island (Dublin). 6th 328yds. From an elevated tee look for the green tucked behind a large dune, with a narrow entrance protected by a bunker on the left. Also the 8th 316 yds. Blind tee shot to a bowl green. either lay up with an iron or go for it. rough ground between 220 and 260 from the tee.
Waterville 16th 330yds. Liams Ace. Tight driving hole with bunkers and OB down the right. Thick right along the right and the best angle of approach from the left. From memory the green slants from front to back. Approaches need to be on the money.
Carne 11th 302-332yds sharp dogleg right that can't be cut. Bunker to catch any shots running long. High dines both sides of the hole. Approach is to an elevated green that rejects all but the most precise approaches.
Carne 12th 280-300yds Elevated tee dogleg left. lay up in the valley then look skywards for the green. well judged PW will get you home.
Tralee 8th 359 - 399. Not really short but forces decision between driver and layup. Tough green to hit.
Tralee 17th 309-355yds Probably using an iron to lay up on a smallish fairway. approach to an elevated gree with a narrow neck
Cruden Bay 3rd 274 yds. Green out of view. Drive through the narrow gap and hpe to find the green. Little margin for error if going for the green.
A course without a tantalising short par4 is missing a key ingredient that may either reward the brave or punish the foolhardy.
