To make the most of this stunning coastal road trip, you should set aside 2 days for your Road to Hana itinerary. This will allow you to take your time on the winding cliff-side road, and to explore each stop at a leisurely pace! Many visitors spend only a day on the Road to Hana, but I don't recommend this.
Is Road to Hana busier on Sunday or Monday?
Sundays and Thursdays are heavy travel days (arriving and leaving the island) so the road to Hana may be less crowded. Start early to get the most out of your day.
Is Monday a good day to do the Road to Hana?
We went today (Monday) and saw very little traffic. Definitely not the bumper to bumper traffic people have described. Make sure you do RTH and the volcano within the same 3 days so you only have to pay entrance fee once if you plan to go to the pools at the end of the road to Hana.
