From Houston: take US 290 west to Hempstead, then SH 6 north to Navasota. As you are coming into Navasota take Business 6 into downtown Navasota and turn left (west) on SH 105. (If you live north of Houston, you can get to Navasota by taking SH 105 west from Conroe.) Go 3.5 miles west on SH 105. Immediately after you cross the Navasota River, but before you cross the Brazos River, turn right (north) on FM 159 and go 3.2 miles (past the cotton gin on the right). As the road bends to the left you will see a gravel road coming in from the right and crossing the railroad tracks (White Switch Rd.). At that point turn LEFT into the dirt road (Camp Road, but no road sign) in the middle of the cornfield and go 1/2 mile to the tall chain link gated fence that marks the property. Once through the gated fence, go straight on the small road toward the mobile home and go around it to the site next to the rapid.
From Austin: go to Brenham on US 290 east and take SH 105 east toward Navasota. Immediately after crossing the Brazos River, turn left (north) onto FM 159 and follow the remaining instructions above.
From College Station: either take Wellborn Rd. (FM 2154) south to Millican and turn right on FM 159, or take SH 6 south and turn right on FM 159. (a) All paved route: Drive 10 or so miles down through Allenfarm and down through the farmland. As the road swings back toward the train tracks you crossed in Allenfarm, start looking for the cotton gin (large white building) in the distance on the left side of the road. When you can see the gin (but before you get to it), look for White Switch Rd. crossing the RR tracks on the left. Imagine that White Switch Rd. continues to the right into the cotton fields and turn onto it (right): that road is the (unmarked) Camp Road.
