In the U.S., the first Saturday of June each year is designated National Trails Day. It’s a great day to leave your hi-tech gadgets behind and enjoy nature.
Besides hiking, you may also be interested in volunteering to help maintain a trail. I am a member of the Potomac Appalachian Trail Club and maintain a section of the Appalachian Trail in Virginia. It’s a good opportunity to give back to the community while using old-fashioned hand tools.
