The annual spring guided weekend hikes atop the Table Rocks by the U.S. Bureau of Land Management and The Nature Conservancy begin Saturday.

There is no fee, but reservations are required. People of any age are welcome to sign up for these free interpretive hikes that have been held annually for 20 years. Participation is limited to 30 individuals per hike, unless otherwise noted.

To reserve space for a weekend hike, call the BLM Medford District office at 618-2200.

Participants should dress for the weather and bring a lunch and something to drink. Restrooms are available at both trailheads. No dogs are allowed on the trails. The hikes range from three to five miles round-trip along a moderate-grade trail. They last three to five hours.

Group weekday guided hikes for 10 or more are also available in the Table Rocks Environmental Education Program beginning Wednesday. Guides are available Tuesday through Friday each week, and hikes begin at 9 a.m. and last about four hours. Because of the popularity of the program, a day should be reserved as soon as possible.

To schedule a hike or for more information, contact the BLM project coordinator Leah Schrodt at 618-2468.

The weekend hike schedule can be viewed on the BLM's Table Rocks Web site, www.mailtribune.com/blm-tablerocks, and The Nature Conservancy Web site, www.mailtribune.com/nature-tablerocks.
