Walking trails are maintained in two main areas of Quivira: the Headquarters area and Migrant's Mile. All of the Refuge is open to foot travel (with the exception of a few areas closed seasonally due to nesting birds). Be sure to park in the over 30 designated parking areas located around Quivira, don't block any gates. Don't leave valuables in your vehicle. Be aware, during wet periods, access to many areas may be limited due to the abundance of scattered wetlands. Use caution in areas of uneven terrain. There is one species of poisonous snake found on the Refuge, the Massassauga rattlesnake.
