Many of the mountain passes along with Trailridge Road across RMNP usually dont open until Memorial Day weekend but that can fluctuate a week or two in either direction so if you plan on driving in the mountains, keep an eye on those before you drive 3 hours to find out your road is still closed.
We use this website to determine what roads are open and it has webcams and stuff so you can see the road conditions at any time.

I would recommend driving to the top of Mt. Evans if its open by then. Its the highest road in North America and you often see wildlife on the way up. RMNP is obviously popular. Boulder has plenty to do to fill up an entire day (hikes, downtown shopping, breweries). Golden is also a good opportunity. If you go to Idaho Springs as others have suggested, eat at Beaujos Pizza and there are 2 or 3 breweries next door. Its some of the best pizza ive had, a lot like Great Plains but slightly better IMO, true "Denver Crust". There are a few of them in Denver too but Idaho Springs has the original.
Downtown Denver has litteral a hundred breweries and great restaurants to fill up an entire week. Downtown Littleton is a fun little area too. The Terracotta Cafe in Littleton has great breakfast and there is a distillery nearby thats good. Stranahan's Colorado Whiskey distillery in Denver has a great tour and is right off I-25 and Santa Fe.
If you like hiking, Boulder, Golden, and Morrison have a lot of easier and shorter options; St mary's Glacier, Guanella Pass, and Lake Brainard areas are all within an hour of Denver and have better views up higher in the mountains, but check trial conditions. RMNP has a lot too but is a bit further away and way more busy. Lots of dogs on most trails and at most breweries and outdoor restaurants so you can bring your furry friend anywhere!
