Regular cave tours, a walk through ancient bristlecone pine stands and evening campfire programs continue to be offered at Great Basin National Park, as the park enters its fall season.

The country's newest national park cut back on the summer schedule on Monday, says Superintendent Al Hendricks. But starting Tuesday, and running through Oct. 1, these activities are available:-Regular tours of Lehman Caves, 9 a.m. to 4 p.m. every day, with extra tours at 11:30 a.m., 12:30, 1:30 and 2:30 p.m. on weekends. The tours last about 11/2 hours and traverse about half a mile of paved trail. A jacket or sweater is recommended, as the cave is a chilly 50 degrees.

-Bristlecone pine walks, led by rangers, take visitors up the slopes of Wheeler Peak, giving a chance to explore a grove of some of the oldest living things on earth. The walks are offered at 1 p.m. Fridays and Saturdays.

The four-mile hike lasts about four hours and covers territory above 10,000 feet elevation. Hikers should be in good physical condition and carry a jack and rain gear. Meet at the parking area at the Wheeler Peak campground.

- Evening campfire programs are offered Friday and Saturday beginning at 7 p.m. in the Upper Lehman Creek campgrounds. The programs cover the natural and human history of the park and surrounding area.

Hendricks said all activities are available on a first-come, first-served basis. Campgrounds should remain open through the month, but water will be shut off at the Wheeler Peak campground when cold weather arrives.

The visitors center is open daily from 8 a.m. to 5 p.m.. The adjacent cafe and gift shop closes at 4 p.m.
