Hi @emarie. There are many trails and activities open now. No word yet on when the mail trails will open, but you can find the remaining ones that are open here: List of trails that remain OPEN during COVID-19
Lake Logan would be a great spot for you and your family to swim. It’s conveniently located right off the highway and close to most activities. https://www.hockinghills.com/lake_logan.html
Other fun activities are canoeing, ziplining, putt putt which is 5 min drive from lake logan. (https://www.hockinghills.com/members/Adventure_Golf_at_Rempels_Grove.html)
