Driving Roads / Blue Ridge Parkway
At 469 miles it is the longest linear park in the U.S., running the crest of the Appalachians with endless overlooks and a relaxed 45 mph pace. It runs about 469 miles along Blue Ridge Parkway in North Carolina / Virginia, roughly 2-3 days end to end of driving.
A long-haul cruise road: track multi-day distance and drive time, and use replay to revisit overlook-to-overlook segments rather than chasing speed.
The speed limit is 45 mph (lower in many spots); slow for fog, wildlife and cyclists, and pull into overlooks to enjoy the view safely.
Open Road is free on iPhone and Android.
