Written Directions
Scenic route from Lafayette to Delphi via Battle Ground. Start near the Purdue campus at State St. and River Rd.
Take River Rd. north for about 5mi, until you see a sign on the right for Battleground.
Turn right on Burnetts Rd. for a short jog over to 9th street, and then turn left on 9th street.
After about 2mi, you should reach Battle Ground. Cross the railroad tracks and continue straight onto main street.
After leaving Battle Ground and passing the country club (2.2mi), take a left onto Tyler Rd.
After the tree tunnel (5.3mi), turn right on country Rd. 150, which will turn into Bicycle Bridge Rd. This will take you to Delphi.
If you're going back to Lafayette, my favorite way back from Delphi is through Americus via Old State Rd. 25.
Scenery
The scenery around the Wabash river is beautiful, if you can avoid the cornfields. This route follows the general path of the Wabash, but avoids most of the corn.
The roads on this route are the twistiest I've found around Lafayette, and there are lots of trees. Battle Ground and Delphi are both scenic, historic rural communities, which are worth exploring on their own.
The best part of the route is Tyler Rd -- it's twisty, wooded, well-paved, and relatively undeveloped.
Drive Enjoyment
Most of the roads are fine. Bicycle Bridge Rd. could use some repairs near the intersection with Tyler Rd., but there is nothing too problematic.
Tourism Opportunities
The only gas station near this route is near I-65, west of Battle ground. Fill up before you leave! The park at Battle Ground has a small visitor center and some beautiful woods you can take an easy hike through.
