This great trail runs from Crown Point to Hammond, spurring off into neighborhoods and other bike trails. The Griffith section is in the middle. Recently paved, I find this to be the most interesting section of the trail. It cuts a block south of Griffith's downtown, near the Historical Park and Depot Museum, pictured here. Just outside of town are some nice, small streches of wetlands and prairies.
Surrounded by a couple of busy roads, a railroad and a few industrial sites, it is amazing just how secuded one can feel halfway into the trail at the Hoosier Prairie. Like the rest of the Indiana Dunes National Park system (of which this is a part, albeit remote) it is a place of contradictions. The view you get is practically the same as what the first visitors to this area got: the meeting of the eastern woodlands and midwestern prairie. It was once believed a squirrel could cross the continent via the branches of trees; the country was so heavily forrested his feet would never need touch the ground.
Here is where that theory begins to lose creedence; oak trees live in harmony with various tallgrasses but heading west from here the trees get decidedly less in number and the grasslands take over.
If you are planning to fully explore the Indiana Dunes be sure to visit this 440 acre of virgin landscape. One note: after rainfall the trail becomes impassibly muddy.
