For this trophy you are required to complete the '1up' objective on one of the holes which is achieved by completing the minimum 'Skill Score' for a course. The easiest hole to do this would be Hole 1 on Britannia as you are only required to get 10,000 points.
An easy way to get that score is to get a few under par, alternatively you could go about collecting coins and the crate on the hole instead as I got around 17,000 doing so.
