My husband and I will be driving from Cheyenne to Denver in May this year. We should be leaving Cheyenne either 14 or 15 May and would like to travel along the I25/US87 until Loveland where we will head West along US34 to Estes Park. We fly out of Denver around lunchtime 20 May.
Firstly I've noticed during my research that "this road may be seasonally closed". I was wondering if this is too early in May for the road to be open and alternatively if it might or might not be open at this time how do we check. Also we have hired a 4 wheel drive but as we are more used to going to the beach than the snow we have only driven in snow on a couple of occasions.
Secondly we are from Australia close to Sydney where our altitude is about 70ft above sea level. We will have travelled through Salt Lake City; Jackson Hole; Yellowstone; Billings; and South Dakota prior to departing from Cheyenne so we will have had a couple of weeks exposure to higher altitude than we are normally used to. I notice that US34 (is this Trail Ridge Road?) is higher than the 8000 ft which supposedly is safe for many without any symptoms of altitude sickness. I've found some organised tours that seem to follow this route too so my question is are we asking for trouble to try this route. Would it be safer to make our way south towards Denver and approach Estes Park from the South?
I don't wish to seem completely paranoid but as the tallest mountain in Australia is only 7310ft altitude sickness is not something I've ever worried about before. I have read as much as I can to be prepared and won't be hiking at all in high altitudes. Any advice would be greatly appreciated.
