Many vacationers schedule watching the sunrise along with a downhill bike tour (37 miles back down to the coast on customized bicycles), an ATV tour or a horseback ride into the dazzling crater itself.  Set your alarm clock because depending on where your accommodations are located,… you might have to head out as early as 2 a.m.  The temperature is surprisingly cold for a tropical island and the early morning air is crisp.  Dress in layers with long-sleeves, and bring a blanket and hot beverages to stay warm.
