The visitor centre is closed on the 25th but could we still access the park for example the Silfra Fissure? Honestly I still don't get the whole idea if all of the park could only be accessed from 1 entrance gate or only some of the attractions such as the Silfra Fissure needs admission and within closed gate?
Places that i'd like to see should be just a stroll away from the visitor centre such as Almannagja, Silfra, Oxararfoss. Not sure if these next attractions easy to access on the 25th of December
