Its 54 more miles to go the 40 route. Does anyone know the before zion?
Our typical way to go (before the boat was in Havasu) was to go the 15 and spend the night in Mesquite, and then get up early the next morning, and head to the lake. If you go through Zion, there is a tunnel, with size restrictions, so a boat is not good to tow through there. I will look up the exit we take, and let you know if someone doesn't post it first. Don't go the 40 way. It is a longer haul, mostly uphill, and eats up more gas. It is a good way to come home though. Come home that way, and overnight at Havasu and add another day of boating to your trip.
