Warrenton - The Warrenton Trails Association, in partnership with the National Park Service Rivers and Trails Program, is sponsoring monthly trail activities in the Warrenton area during the summer. The series will kick off Saturday, National Trails Day, with a trail construction project and continue with guided trail walks in July and August.

On Saturday, volunteers are needed for WTA's Community Trail Crew to help construct trail on behalf of the Lewis and Clark National and State Historical Parks. Volunteers will work side-by-side with National Park Service staff on a section of the Fort to Sea Trail, a trail replicating Lewis and Clark's route from Fort Clatsop to the Pacific Ocean.

Ten people are needed for the volunteer crew, capable of a full day on the trail, including packing in gear and using hand-tools. People who would like to join WTA's crew are asked to register with the Warrenton Trails Association at 861-2001. Volunteers will meet at 8:30 a.m. at the Serendipity Caffe, 137 Main Ave., Warrenton, to carpool. People should wear suitable clothing and bring boots, gloves, lunch and water.

On July 17 there will be an Airport Dike Trail Walk, a flat 5-mile trek. Those attending will meet at noon at the northeast corner of the Premarq Shopping Center parking lot. There is no limit on the number of walkers and leashed dogs are welcome.

Aug. 21 will feature the Skipanon Peninsula Trail Walk. Walkers will meet at noon in the the Premarq parking lot.

The mission of the Warrenton Trails Association is to enhance and expand the system of trails on historically significant public lands in the Warrenton area, in collaboration with land managers and the public and with stewardship of the natural and cultural resources. For information, call 861-3669.
