I highly recommend a visit to Estes Park and Rocky Mountain National Park....very beautiful. You just drive north of Boulder about 1/2 hr. On I-25 to Hwy 34(Loveland) then go West about 1/2 hr, 45 min and you will be there. Spectacular scenery nestled in the Mountains. On I-25 just North of hwy 34 at Crossroads Blvd (it's the next exit after why 34) there is a HUGE Harley Davidson Dealership. HUGE!!
So if you want to see all that I would drive up I-25 to Crossroads Blvd West to the Harley Dealership...spend some time there...get directions to Nordy's BBQ restaurant...nearby, and yummy, have lunch there then go west on Hwy 34 up to Estes Park and Rocky Mountain National Park. A really nice day trip.
Or. Go to the Harley Dealership, run up to Estes and RMNP spend the day and on your way back to I-25 run over to Nordy's for dinner. Either way it's a good day.
I live in Fort Collins, about 10 miles north of the Harley Dealership so I am quite familiar with the whole area. I LOVE Estes Park and Rocky Mountain National Park.
If you do go to Estes Park be sure to keep your eyes peeled while in town.....there is a herd of elk who live in and around town, often by the golf course or the famous Stanley Hotel. The elk just wander around and are seen frequently. Visit the Stanley Hotel to see a bit of history and see where the Movie The Shining was filmed. The Stanley was built by the guy who invented the Stanley Steamer car! It's a beautiful property.
Enjoy your trip!
