Two sites in Texas are among 31 trails in 15 states newly designated as national recreation trails.
Secretary of the Interior Ken Salazar on Tuesday announced the designation.
Knob Hills Trail is on the west end of Grapevine Lake. The 5.43-mile Knob Hills Trail is a natural surface trail commonly used by hikers, bicyclists and people on horseback.
Currently Knob Hills Trail is open to hikers only. The U.S. Army Corps of Engineers manages the trail and is currently rerouting and redesigning parts of the bike trails, and that work had been put on hold due to recent rain. The ACOE said Tuesday it hoped to have the bike trails open to the public in the next week or so.
The designation recognizes existing trails and systems that link communities to recreational opportunities on public lands and in local parks.
