The weather can be really unpredictable in the spring time. It can be 85 degrees, or we could get snow (but don't worry, if it snows, it will likely be gone by the next day). Lately it has been fairly warm and dry. Today it's going to be near 70 degrees, but averages in early-mid April are probably somewhere in the mid-high 60s for a high. It gets cold at night, and it will be cold in the mountains, so make sure you have clothes for layering.

Many mountain towns have an "old west" sort of feel- also Golden, which is on the west end of the metro area about only about 20-30 minutes away from Denver. Georgetown and Idaho Springs (fairly close mountain towns) were once mining towns and are nice, plus have a few museums. Also Evergreen is close and nice- it's one of my favorite places to hike because it's perfect for an afternoon trip, and coffee shop in Evergreen is really cool, it's build into a rock. There are so many parks near the area I think the only trouble will be deciding which to hike at. I would really say you have to go to Rocky Mountain National Park though, it's so beautiful, and only about 2 hours away from Denver.
