Warning: Watch for potholes on all paved roads.
Warning: Most dirt roads in the park require high clearance of 8" or more and 4-wheel drive and some knowledge of driving on rough dirt, gravel and 4-wheel drive roads. Road conditions can change quickly and cell phone signal is speradic and does not work throughout most of the preserve, so do not rely on them. Check with a Ranger on vehicle requirements and conditions on the specific roads you plan to travel before you leave the pavement!
