It sounds like you're going to head down to Walsenburg and back around to the Sand Dunes. If I could offer a suggestion, I'd drive to Colorado Springs..take 115 to Penrose and then to Canon City. Much prettier drive along the Arkansas River to Salida...you can fish anywhere along the Ark..gold spinners work well..rather than driving the loop around through Walsenburg. If you decide to stay in Salida for a night..you can camp and fish at O'haver Lake. From there, I'd do an out and back to the Sand Dunes.
After going up and over Monarch Pass, and down into Gunnison...once again, if you have time..I'd take a side trip through Almont on over to Taylor Reservoir..beautiful drive. If not, I'd definitely stop at Morrow Point and take the short hike down below Blue Mesa's dam. Fish the stretch below the dam with a quarter ounce jighead and black and grey gulp minnows. Beautiful place.
From there, I'd definitely hit the Black Canyon of the Gunnison..beautiful place and you can drive down and fish the Portal. Once again, depending upon your itinerary, I'd take a side trip to Ouray and then take an out and back over Red Mountain Pass to Silverton. One of the prettiest drives in Colorado. Recommended place to eat in Silverton..Handlebars.
From there, if you have the time, I'd drive back to Ridgeway and take hwy 62 to 145..to 141..141 is a fantastic drive to Grand Junction..much...much prettier than taking 50. While in Grand Junction, I'd definitely check out the Colorado National Monument..fantastic..and if you have the time...the arches in Rattlesnake Canyon..I think they're better than the Arches in Moab. If you ride mountain bikes ...let me know and I can give you some ideas on some great trails to ride.
In Glenwood, a great day trip is the drive up to Marble and back..beautiful drive..there's also a small lake that you can fish in Marble. The Marble used in the Lincoln Memorial came from Marble Colorado. If you'd like to hike in and fish a high alpine lake near Aspen, let me know and I'll PM you the directions to a beautiful lake..Also a good quick hike is Hanging Lake. No fishing there.
On the way back to Denver, I'd take 9 out of Silverthorne to 40 and then 34 into Granby and Rocky Mountain National Park..Just drop down trailridge into Estes. If you'd like to know about any good hikes or lakes to fish in the park..let me know.
Just a few suggestions..
As far as lures..Slayer gave you all you really need for the trip.
