Iceland: I especially like the Laugavegur trail but also Hornstrandir and other places. I hiked/ran the Laugavegur 10 times and even did a solo winter expedition with snowshoes! Worth to mention is the Laugavegur ultra run!
Sweden: Sarek is my favorite place, as one of the few remaining wilderness regions in Europe!
Norway: So far I visited Jotunheimen and Svalbard and I can recommend both!
Italy: Here the dolomites are a highlight if you want to visit the Alps! I can recommend the area around the "Drei Zinnen".
Switzerland: Some nice places in Glarner Land. Spectacular mountains like Matterhorn, Eiger, Piz Palü!
These items I see as essential in my whole equipment and build the basic blocks!:
My additional gear varies depending on the planned hike. Usually I carry 10-20kg of camera equipment, my iPad and solar energy for recharging! As outdoor food I prefer "Real Turmat" from Norway and "Back Country Cuisine" from New Zealand. Sometimes I also carry mountain equipment like ice-axe, crampons and weather-proof clothing for extreme conditions!
