We like visiting museums on trips and we were with a group of friends for a 30th birthday. Train ride was easy from Nørreport near the centre of Copenhagen to Humlebæk and then a 10 minute walk (easily signposted). Fantastic collection of paintings, ceramic and sculptures (Picasso, Henry Moore, Lichtenstein and a great visual installation by Yayoi Kusama to name a few). The grounds are also lovely to wander as the museum is on the seafront. Only criticism is that a student card only reduces the entrance fee from 115 to 110 Kr! Definitely worth the effort to visit.
