Trip Plan
To make the most of this 4 hour and 50 minute trip, aim to depart early in the morning to avoid fatigue on the winding local roads.

Because this is a turn-heavy drive, double-check your navigation settings frequently to stay on the correct path through the various local streets. The flexibility of a one-day timeline allows you to set your own pace, so prioritize safety over speed on these non-highway stretches.

Seasonal Notes
Summer travel usually means heavier construction, hotter rest stops, and busier weekend traffic around major cities.
Winter travel shortens daylight, so a route that looks manageable on paper can feel much longer after dark.
Holiday weekends tend to make both departure and arrival windows slower than the raw route time suggests.
Time zone
Same local time
Origin and destination are on the same clock, so arrival timing is easier to judge at a glance.
Temperature spread
12 degrees warmer at arrival
A meaningful temperature swing is a good cue to rethink layers, water, and how soon you want to arrive.
