Sprain Ridge has some very technical sections of log crossings, often two or three in a row spaced about a bike length apart just to make things difficult.
Here is the description from the official website:
Sprain Ridge Park is a large land preserve with a variety of landscapes, ranging from heavily wooded areas to large and impressive rock outcroppings. The park was previously owned by the Boyce Thompson Institute, a botanical research center, and a result, contains many unusual and exotic woodland plants. The five miles of mountain bike trails at Sprain Ridge offer challenges to cyclists at every level of ability and are a great complement to the parkís other recreational facilities, which include a swimming pool, playground and picnic areas. The trails wind their way through 278 acres of varied terrain that offers challenges for beginner, intermediate and advanced cyclists. The beginner trail provides cyclists with challenging curves but a relatively level topography.
The intermediate and advanced trails provide experienced cyclists with more of a challenge with trails of increasing grades and challenging topography.
There are picnic areas available near all three parking lots and a snack bar is open in season near the swimming pool area.
Remember, people judge all cyclists by your actions, so please act courteously and responsibly. not build new trails or stunts. Have a good time and enjoy your ride.
