Help!! First time going solo!

Hello! I have been wanting to do a solo trip, but I have always been so scared to do it. I finally decided to do it this year to cross that off my bucket list🥺. Hoping to do it around July or August. I’m a female in my late 20’s. When I travel I usually prefer more of a nature/island vibe (touching grass lol). I’m also a big foodie and I think that’s the best way to really learn about the culture of the place you’re visiting (besides reading about their history ofc haha). I like excursions and activities versus lounging at an all inclusive😭. I came here because I was hoping to get some tips on how to get started. I thought about joining travel groups but unsure if that’s the best route or actually try and plan it on my own. Any advice would be much appreciated!
