Many people want to know about the hikes I lead so they can join in. Although I do post some hikes here, most go on specific area Meetup boards.
For the Ithaca/Cortland area, check out the Meetup Group Ithaca Area Hiking and Nature Study Group. You can find them at: https://www.meetup.com/Ithaca-Hiking-Nature-Study-Group/
For the Syracuse/Cortland area I post for the Syracuse Outdoor Adventure Group on Meetup. You can access them at: https://www.meetup.com/adventurers-103/
Hope this helps you to be able to join us on hikes and other activities the Summer.
Best wishes, as always.
