New Year Hiking Groups for Solo Travelers?

Hi! I'm a soon-to-be 27 y.o. female, and it so happened that right now I'm at a place in my life where I will have nobody to celebrate New Year's with back home. All my friends have coupled up and are planning to celebrate separately, and I don't want to be their pity invite, and also I really don't want to spend that time alone in my apartment, hating every minute of it and pitying myself either haha 😅

I'd love to go on a hiking trip with some nature-minded people somewhere beautiful. I'm located in Lithuania, but I'm thinking of getting plane tickets early and flying out before NY, so somewhere in Europe would be ideal! I'm thinking maybe somewhere northern as well, cause I'm really feeling some beautiful winter forests and gorgeous mountain views! So countries like Sweden, Norway, Finland, Iceland, the U.K., Ireland, just to name a few, could work I think!

Have you guys heard of any hiking groups/events of this kind I could look into? Preferably where there might be more solo travelers so that it wouldn't feel too awkward being surrounded by couples and friend groups while being on your own? 🤣 I can't really afford any fancy retreats, but a hiking trip + staying at hostels + maybe even some wild camping or saunas?? sounds amazing. Something that would allow you to be in nature but also not feel too lonely by being around other people in their 20s/30s who are also going through something or are alone for one reason or another?

Thanks so much! ☺️
