Dude, you don't really just "hike around" out here without knowledge. What you need to do is make friends and get on their program. I mean if you're talking about a slight hill because you want to hit a back yard jib or something that's cool. Please don't be one of those idiot kooks riding Loveland pass with zero knowledge of the terrain, no BC skills and no equipment.
CO doesn't have the biggest baddest terrain not by a long shot but it does have just about the deadliest snowpack in the country, not a lot of snow relatively speaking, leads the country in out of bounds and inbounds deaths, and they call it the Rocky Mountains for a reason.
Go take an AIARE1, get a beacon shovel and probe and get some friends! People that have lived here and played in the BC here for years are who you need to link up with. How old are you and what's your ski background? PM me if you have more specific questions about specific terrain on the front range or if you wanna link up
