Knox hikes are on hiatus during the pandemic. Normally hikes take place each spring and fall on a Saturday morning led by members of the congregation. Previous hikes have been to:
- the C&O Canal in Maryland;
- Huntley Meadows Nature Park,
- Burke Lake Park,
- the Mason Neck National Wildlife Refuge in Northern Virginia;
- the National Arboretum in the District, and
- several stretches of the Cross County Trail in Fairfax County.
