For the tail end of your trip, to RMNP and Moraine Park, there are a couple of options.
On US 285 when you get to Aspen Park, shortly thereafter there will be a long downhill through Turkey Creek Canyon, but it is 4 lanes and a good road. Just watch your speed -- gear down and keep it at or under the speed limit. Town of Morrison PD is aggressive in enforcing the speed limit. When you get to CO 470, head north toward I-70. Once you get to I-70 you have a choice.
Stay on CO 470 and go into Golden where it intersects with US 6. Take US 6 into Golden where it meets CO 93. Take CO 93 through the remainder of Golden and stay on it all the way up to Boulder. In Boulder CO 93 becomes Broadway/CO 7 through the city and CO 7 intersects with US 36 north of the city. US 36/CO 7 north to Lyons, then in Lyons stay on US 36 up to Estes Park.
Alernatively -- instead of going into Golden and the traffic of Golden and Boulder, where CO 470 intersects with I-70, get back on I-70 and head WEST to the exit for US 6. Make sure you are in the right lane down a ginormous hill and watch for the US 6 exit as it can sneak up on you. Take US 6 east to CO 119 and then take CO 119 north toward Black Hawk and stay on it all the way to Nederland. In Nederland pick up CO 72/the Peak to Peak Highway and stay on that until the intersection with CO 7. Make a left and go through Allenspark and Meeker Park and on in to Estes Park.
IF you miss the US 6 exit, not to worry. You can get off I-70 at the Central City Parkway and take that up to Central City/Black Hawk. Just follow the signs through both towns for CO 119 where you pick that up in Black Hawk and follow the directions above.
As you come in to Estes Park on CO 7, watch for Mary's Lake Rd. Make a left and take it down to where it intersects with US 36/Moraine Ave. Make a left on to US 36 and you'll be just about to the Beaver Meadows entrance to RMNP. There's a good visitor's center there. At the entrance gate let them know you have a reservation in Moraine Park; that will be your timed entry into RMNP. Print out a copy of your reservation confirmation before your trip as added proof of your reservation. Turn off US 36 on Bear Lake Rd and stay on that to the entrance to Moraine Park.
None of this is difficult towing. Many folks at various experience levels do it all the time. Just take your time and enjoy your visit!
