There will still be snow in mountains around denver
IMHO Fruita / Grand Junction is well worth the trip from Denver
The trails are great – 18 road trails are smooth fast rolling singletrack – they have recently added some trails with gap jumps etc as well
If the snow has cleared from the top of the book cliffs the edge loop is a nice big loop – at one point you have to lower your bike down a cliff on rope
The Kokopelli trail system is also great if you do all the trails theres around 40 miles of singletrack to ride there -more rocks here (moore fun is very techie) and great views
Also you have the trails down towards rabbit valley – theres a nice big lop ride called the zion curtain down that way
There the Lunch Loops in Grand Junction – which are a more technical than the above
Also you have the pallisade rim trail in Pallisdaes which is worth doing
I’ve often driven straight to Fruita from Denver (Just make sure you check the traffic when you are heading back to denver – as the freeway from silverthrone to denver can get very congested at weekends)
Check out my website for some of my trips out Fruita way

Theses sites have lots of info on the riding down that way
