Wellness retreat

Hi all!

Mom of two turning 30 and hoping to spend it doing a solo welness retreat, preferably in the US but open to anything relaxing, self help, hiking, but preferably lots of activities so not just sitting around a pool or in a spa but more so like a learning holistic kind of thing. I want to do it on my own so would love a place where I can meet people there but still be solo. please send any recommendations thanks!!
