Denver locations for outdoor E-session

I live in Kansas but will be traveling to Denver within the next couple months to do an outdoor engagement session with my niece. I have asked her for suggestions as to where she wants her photos shot and is in the process of finding some places, however, I'd like ideas from anyone in or around the Denver area as to great, romantic places to shoot.

Any suggestions?

Thanks, in advance.

Haven't shot in Denver for a while, but I used to live there.
For urban cityscape type, you can go down to 16th street and walk around or get on the shuttle bus along there. For parks, Este park is one of the best if you don't mind the drive, otherwise another big park is around Florida street & Santa Fe if I remember correctly.

How about Red Rocks Park? It's just up in the foothills outside Denver and has many different looks. It's free to access and isn't that difficult to get to. It offers views of the mountains and of course the Red Rock formations all around you. It's a really amazing place and one not to be missed.

Red Rocks, 16th street mall---these are great places. depending on where she lives.
