We like to take the family to Roxborough State Park on the southwestern edge of Denver.  The Fountain Valley Trail is an easy to moderate hike of about two and a a half miles that is beautiful in the spring with the plants and wildflowers.  We usually see herds of deer and occasionally a fox or coyote.  The red rock outcroppings are really neat.

I am planning to visit Estes Park in June.  Can anybody give me recommendations for a good pizza restaurant. 
Thanks
