We live in Highlands Ranch and have a 13, 10 and 1 year old. While I agree with prior posters that there are currently issues with the school board, that can be true in some of the neighboring areas as well. My 10 year old is in a fantastic school and has had Mandarin since 2nd grade. My 13 year old I ended up pulling out of our neighborhood middle school and moving him to a different school. In Colorado you have the option of open enrolling so you really do need to look at each school individually. DS 13 is looking at a high school in Highlands Ranch, one in Littleton and actually one in Parker for next year. The HR school is our neighborhood school but with open enrollment as long as I can get him there he can go anywhere if there is room.
As a PP mentioned we have great rec centers, youth sport leagues, events for most holidays etc. It really is a good place to live.
Not every district in Colorado has open enrollment, so that is something that should be checked out if important to you.
If the school district is important to you, the two highest ranked in the Denver Metro area are the Cherry Creek district and the Boulder Valley (does have open enrollment) district. Although, that said, there are fabulous schools in all the districts in the metro area, you just need to check them out.
However, at this time, as somebody above stated, I would stay well away from the Aurora schools as they have had quite a few problems. Although, Aurora Quest Academy is one of the highest ranked schools in Colorado. Adams 14 is another I would research very closely before I purchased a house in that district.
Where and how do you want to live? Highlands Ranch, the Cherry Creek district and surrounding area are the most congested areas in the Denver area. There is good and bad to that. Lots of people, but better public transportation. More congestion also means more shopping and dining options. South Denver (Highlands Ranch, etc) has more of a metro feel to it.
The Boulder Valley District is up in northwest part of the Denver Metro area. It is very highly ranked nationally and flip flops with Cherry Creek as being the #1 district in the state.
BVSD (Boulder Valley School District) has the only school in Colorado that is ranked in the top 50 in the nation - Peak to Peak, which is a k-12 charter school. It is an outstanding school. The high schools are also ranked in the top 100 with a huge selection of both IB and AP courses.
Louisville, a bedroom community of Boulder was ranked the #1 place to live in the nation in 2011 by Money magazine with its neighbor community, Superior, ranked #13.

I am in Boulder, but my closest friend (and who got hooked on the DIS) is in the Louisville/Superior area. She loves it. Schools are second to none and you get the Boulder quality of life at half the price.
Forbes has ranked Boulder as the brainiest city in America for 3 years in a row due to the technology and major science research centers. And those brainy people often help out in the schools which is what pushes them to the top of the pack. CU (University of Colorado, Boulder) just completed a biotechnology campus that is set to put them as the #1 ranked biotech research center in the country, so lots of technology options here.

Boulder in the past year or two has also been ranked the #1 healthiest and #1 greenest cities. This may or may not be a good thing as the healthy, outdoors mentality is almost cult-like. Even the elementary schools train for marathons.
I love the mountains and all the hiking trails we have available to us in Boulder. South Denver and the metropolitan, congested feel is not for me. However, the outdoor (parents often show up at PTA meetings in their biking shorts and shirts), healthy living cult-like, birkenstock mentality is not for everybody either.
If you want outstanding schools in a less congested, suburban feel, give the Boulder Valley School district a look. But as with all districts, there is a range in quality of schools. I would say the best are in the Boulder, Niwot, Louisville, Superior areas.
