To get to the trail head at the San Pedro House from Bisbee take Hwy 80
North 9 miles to the junction with Hwy 90. Turn West towards Sierra Vista
and drive 7.5 miles. Just West of the river is a big sign on the left (South)
side for the San Pedro House and the San Pedro National Riparian Area.
There is a bookstore here with some trail supplies for sale. Also water,
shaded picnic tables and toilets are available. The GPS coordinates are
N_31-32.896 W_110-08.498. If you are coming from Tucson take Interstate
10 East for 37 miles then turn South on Hwy 92 to get to Sierra Vista then
Turn East on Hwy 90 and dtive 7 miles to get to San Pedro House.
