We plan to visit Thingvellir, Geysir, Gullfoss, carter Kerid, Seljalandsfoss, Skógafoss, Reynisfjara Black Sand beach, Foss á Síðu, Skaftafellsjokull Glacier trail, Svartifoss, Jökulsárlón Glacier Lagoon, and Diamond Beach. I think all of these are very short and easy hikes, please correct me if I'm wrong.
For the snowmobile and ice cave tours I think the tour will provide for special boots and/or equipment. I do not know if the Northern Light tour will provide equipment.
We would really appreciate if someone can recommend if we need to purchase Yaktrax or Microspikes to safely walk on the places we plan to visit or while aurora huntings at night? Thanks.
