Some of these below might be yellow or red staked hazards. Some might even be classified as OB so therefore not applicable.
The 14th at Cruden Bay is one example of such as hole that comes straight to mind. I've seen it played from the beach a few times, once all the way from the waterline when the tide was right out, which is a pretty long way.
Some other examples would be the 1st at Machrihanish, the 1st at Royal Jersey, the 9th at Dornoch, the 1st at Royal Aberdeen, the 3rd, 4th & 5th at Golspie, the 9th at Brora, the 11th at Tain, even the 11th at TOC. There must be a few holes at Deal/RCP that this could apply to. I've even heard a story about a hole at Tralee, don't know it's number, where some folk allegedly play on to the beach deliberately, but I've not been there so can't confirm if this is correct/possible or not. And as I said above, some of the holes mentioned above might have the beach area classified as OB so therefore not applicable.
All the best.
