Twin Arch Reserve sits along the Great Miami River and is a great place for hiking, biking, fishing, kayaking, canoeing and viewing wildlife. A highlight of the park is the renovated, historic Miami-Erie Canal Twin Arches. The arches were originally built in 1837 and are one of only two structures of its type in Ohio. The park includes a five acre pond, with fishing access. The fishing is catch and release and a state fishing license is not required, however if you choose to fish in the river make sure you have your license handy. If you prefer nature trails, there is nearly one mile that winds through the park and by the Natural Play Area where children can play in the woods.
