Regular hiking is good for the body and the mind. Several Meetup groups have regular hikes in the Austin area, as does the Sierra Club and others.
I have regularly hiked with the Monday-Friday Hikers for 7+ years. Most of us in the group do not work a regular 9-to-5 job, so our hikes begin at 9:30 AM. We usually walk for 1 to 3 hours.
We do not recruit new members directly. Instead, we encourage people to take the “Hiking Austin Trails” course given by Austin’s Lifetime Learning Institute. Tuition for that course is just $20, and it meets 8 times for hikes on some of the same trails that the Mon-Fri Hikers frequent. Anyone who is comfortable with the Hiking Austin Trails hikes is welcome to join us.
