Nice balade. Leave early to allow fresh air in summer time.
Better to do the road from deadsea to Madaba.
Arriving just before Madaba the view is spectacular.
2.30 to 3h without stops.
The road isn't perfect but the bituminous from dead sea to madaba is relatively good and allow for nice turns.
Attention many sharp turn with limited friction and bumps.
Make sure your bike has enough coolant as the dead sea is particularly hot for bikes.
Attention to radars.
Deadsea museum has a restaurant with very nice view and affordable prices.
Plenty of nice options in madaba.
