Connecting with a Judaism & Israel

I was raised secular / Jewish home without much observance. I have a small extended family, limited Jewish bkgrd and no children I am 53 I married someone who is not Jewish. I visited Israel in 1987, 1993 and 2006 these trips had a major impact on me, and I wish I could be more connected to Israel ., but short of going there, I don’t know how . I dabbled with studying Hebrew, and toyed with the idea of joining a synagogue, but in my town (my town does not have one I would go to a neighboring one) feel like they are mostly for families. I don’t have kids and would feel weird being in that environment by myself …maybe. What other ways could I engage with Judaism or Israel?
