Here is a look at each.

This club — Trump’s first — opened in suburban West Palm Beach in 1999. It reportedly counts some celebrities among its members. When visiting Mar-a-Lago, the president makes at least one drive over to this club, where he plays a few holes, eats lunch and takes calls.

Don't try to get a tee time here, unless you know a member. This course is one of several Trump Organization private clubs. Trump purchased the course — which was built on a former bison farm, according to the club's website — in 2011.

Trump has a massive estate near this course, which he purchased in 2002. Jim Fazio, the Jupiter-based golf course architect behind Trump's West Palm Beach links, also designed the 18-hole Westchester course.

It’s been reported Trump plans to pair his Bedminster club with Mar-a-Lago as a weekend retreat while he’s in office. Trump National Bedminster features two 18-hole courses, and will host this year’s U.S. Women’s Open tournament.

This club opened in 2005 and includes an 18-hole course that has a unique feature: a 19th hole, perched beneath the clubhouse's terrace.

Located in Pine Hills, N.J., Trump National Philadelphia sits on "southern New Jersey's highest point providing views of the Philadelphia skyline throughout the course," according to the club's website.

This course opened in 2012 and was designed by legendary golfer Greg Norman.

This club, which recently hosted a Senior PGA Championship event, was purchased by Trump in 2009. Since taking office, Trump has made several trips to this course to play golf and hold meetings.

Anyone can play at this public course, with a mid-morning tee time in May clocking in at $275. Golfers also can sign up for the VIP program, where for a $695 annual fee, they can play for $160 anytime. Trump spent $250 million on the club, making it one of the most expensive in the world.

This course opened in 2012 and was met with rave reviews, including one in The Palm Beach Post. Earlier this year, the local Scottish council approved an expansion at the club to add another 18-hole course, Golf Digest reported.

Trump purchased this historic course, originally opened in 1906, in 2014. It features three courses and a resort, and has hosted The British Open and other major U.K. golf tournaments.

Trump bought this Doonbeg, Ireland, course for a reported $20 million in 2014. Morning tee times at the oceanside links run at about $191.

Trump's first golf course venture in Dubai opened this year as part of a larger development project by Damac Properties Dubai Co. PJSC. The development features apartments and villas, and a 30,000-square-foot clubhouse, Bloomberg reports.
