In reply to Max BB:
With just a week I think there's one obvious answer and that's to go to Boulder. It's a nice town with many excellent bars and beers. It also has Dot's Diner for excellent breakfasts and Freddie's Hot Dog stand; Freddie (Fred Snalam of Preston) is long gone I'm afraid, having been killed climbing in La Grave some years ago but I believe it's still run under his name. Oh - and there's a little bit of climbing locally too!
The Flatirons are actually within the city limits and very very accessible and have many moderate climbs.
Straight out of town is Boulder Canyon with roadside crags with routes of all grades. And at its top is Nederland where you should go. If it's as it was in 1999 you'll know when you get there why I recommended it.
The unquestioned gem is The Redgarden Wall of Eldorado Canyon and it has some good climbs at 5.6, 5.7 and 5.8 among the harder fair. Also at Eldorado is The Bastille, and Bastille Crack is among the very best VSs anywhere.
We've climbed there in July and August and it wasn't too uncomfortable though a little sack with water is advisable. If it's too hot for you, as others have suggested, it's not a long drive to Rocky Mountain National Park where the buttresses of Lumpy Ridge have short approaches and grades to suit everyone. It might be that with only a week sussing and preparing for the Alpine rock climbs there would take up too much time?
About 50 miles South is The South Platte River climbing area - crags are pretty spread out but some of 'em are at over 8000 feet "where the air", as Sammy Cahn put it "is rarified" and it's cool in more ways than one. We hadn't realised and wondered why we were breathing heavily on the short approach to Sheep's Nose!
You could do worse than go onto the Mountain Project site. They have a facility where you put in the area and grades you want and it comes up with a tick list for you.
We used a 1990s Colorado Climbs guide book which is a selected climbs volume. Pretty dated but tells you a lot to whet your appetites. There's an updated version now. I just looked it up and found you can get it cheap: https://www.amazon.co.uk/Colorado-Routes-Falcon-Guides-Climbing/dp/07627382...
Have a great trip. I loved it there and wish I'd been back.
