@contentandwell Hi JK. Colorado is a pretty big place and it will take some time to drive to places. PIne is southwest of Denver, and Estes Park (Rocky Mountain National Park) is northwest of Denver, and that might be 3 hours to travel between them. The Grand Canyon is far away. You probably need to plan extra days to go there and to make sure you have enough time to enjoy it when you get there. You can't really imagine how big the Grand Canyon is until you see it, and the colors change with the time of day. I took the mule trip to the bottom from the South Rim some years ago and stayed at Phantom Ranch. It's a 5 hour ride down, and the mules cross a bridge over the river at the bottom. Whatever you do, I'm sure you'll enjoy it. If you have trouble with the altitude, make sure to take it easy and drink lots of water.
