I'm planning a day trip to Hilo coming from the Colony Villas on a Wed, and I would greatly appreciate some input on a few questions:
1. Should we make a stop at Waipio Valley Lookout on the way there or on the way back? How much of a detour is it timewise?
2. Are there any concerns driving back on Highway 19 in the dark?
3. I'd like to see the waterfalls, Hawaiian Botanical Gardens, farmer's market, the rainforest zoo, Lilioukalani Gardens, and Big Island Candies, and make stops along the Hamakua coast to enjoy the scenery. In what order should I do this to make the most efficient use of time? And is this too much to do in one day? Should I do Hilo and Hamakua coast on separate days instead?
Thank you for your help!
