This trip will be my third road trip with my boyfriend. The first was to New England and the second was in the Southwest. This next trip is a 16 day trip and just over 5,000 miles. We are thinking Day 1 and 2 we are leaving Chicago around 4pm and heading for Billings, MT. Along the way we are planning on seeing the Badlands, Wall Drug, the Black Hills Scenic Byway, Mt. Rushmore and Devil's Tower. This is a long day of driving but we know we can do it because on our last trip we drove straight through from Chicago to Albuquerque. Day 3 we will be driving to Kalispell, MT hopefully stopping at a ghost town and Flathead Lake. Days 4 and 5 will be spent in camping in Glacier NP. Day 6 will be a drive along US-89 arriving close to Yellowstone. Days 7 and 8 will be spent exploring Yellowstone, we will also be camping here. On Day 9 we depart for to Salt Lake City, UT stopping to enjoy some scenic overlooks in Grand Teton along the way. On Day 10 we will continue on to Moab, UT. On our last road trip we got a flat tire in Arches NP so we did not get to do everything in this area we wanted to since our car was in the shop getting two new tires, quite the bummer. We want to do hike to Delicate Arch as well as do the Fiery Furnace tour. Day 11 we will stay in the Moab area, going to Dead Horse Point SP for a portion of the day. Day 12 we head for Durango, CO. On this day we will see Monument Valley, 4 corners, Mesa Verde NP, and Canyon of the Ancients NM. Day 13 we are going to Great Sand Dunes NP, Garden of the Gods, and Cave of the Winds. We are also deciding if we want to drive up Pike's Peak or take the train. Day 14 and 15 are driving home. This leaves one extra day to add into the trip. Any suggestions on where it should go? We were thinking in Colorado. Any must off the beaten path must sees? Trail suggestions? Restaurants? Tours? Also, we were considering bringing our dog Ivy, a 10 lb toy fox terrier, but are currently thinking it might be best to leave her at home because we arent sure about what to do with her when we want to go hiking. Would it be best to rent a car for this trip or to use our own new car? Our budget for this trip is $4000. We are planning on leaving the third week in July. Any suggestions would be greatly appreciated!
