My son is getting married Sept 24 near Granby Co.
I am looking for a small house to rent for 10 -14 days in the area of Denver to Granby.
I need a place that allows dogs and has a fenced yard.
We were out there 3 years ago and had a nice place in Arvada but it is not available any more.
Any help appreciated!

I would suggest searching AirB&B or VRBO. The wife and I have had luck doing that!

I don't kniw of any listing resources other than AIRBNB and VRBO this, maybe worth looking at CO Craigslist for the random one not listed elsewhere.

It's pretty in Granby.

I thought this was gonna be for a vacuum truck to clean out a septic tank.

I thought maybe one of our sig forum family might have a property that would work. I would have liked to been able to support them first.
But we found one on VRBO in Northglenn.
Would still consider other options if the come up.

We use to do family reunions at the YMCA Snow Mountain Ranch which is near Granby. Perhaps they will have a rental cabin that meets your needs.

It's been 15 or so years since we've been there and I know they lost a lot of trees due to the pine beetle issue. It was on the rustic side but always clean and functional.

If you like hiking, fishing, and/or being outdoors, there are things to do at the ranch and it's close to the Rocky Mountain National Park and to Winter Park.
