Colorado Indian summer.

"Not Native but I got here as fast as I could" - this is common bumper sticker you will find on vehicles of those people who live here and truly love Colorado. I consider myself one of them, hence few years ago I started professionally showing it to others (after I practiced it for 10 years on my relatives and friends).
Colorado is beautiful colorful state, and also the most mountainous state. We've got Rocky Mountains! They came with 320 sunny days a year, very mild winter, hot summer, warm, long and very  pleasant fall.  Most people who come to visit Colorado, come to see natural  beauty, wildlife, mountains, canyons, water falls. It is not like busy New York City or partying Miami, but it is true USA too. 

Things to do in Colorado Springs

If you think of coming to Colorado Springs and spending some time here, I have a few ideas for you. There is always plenty to do here at 6035 feet above sea level. There are endless activities to keep you busy for a day or a month.
First of all - do a tour and get outside! It is literally essential in Colorado! Go hiking (or just leisurely walking) on one of many Colorado Springs hiking trails which are free and beautiful. You will be amazed by these mountain views, clean air, blue sky 325 days a year. With abundance of wildlife , you might get lucky and come across of some deer, big horn sheep, red fox, or coyote, not to even mention tons of birds, squirrels, chipmunks and some other small curios Colorado creatures.
If you are not a hiker, you can also ride a horse (there are several stables in town which  offer 1, 2 , or 3 hour long packages), or do some regular or mountain biking, but consider the weather. You don't want to start your riding experience at 11 a.m. in July, simply because it gets too hot in the afternoon. You can also try your hands and feet at rock climbing. Colorado Springs is a mecca for scaling rock. Garden of the Gods has some excellent classes for beginners  as well as for advanced climbers.
So, get up before 8 a.m. and get outside, you won't regret it.
After your outdoor time have lunch at one of downtown Colorado Springs or Manitou Springs, or Old Colorado City restaurants. Study the sculptures on an art walk as you are digesting your food, or try some mineral waters if in Manitou. The water is free and you can locate several drinking fountains in town. Manitou Springs also have a great shopping  opportunities as well as Cave of the Winds, Indian Cliff Dwellings Museum, and it's own Castle - Miramont Castle.
Number one attraction of Colorado Springs is Garden of the Gods. It is a city park created of natural giant red rocks. This place is rich in scenery and history. Make sure you visit it. Just south of the Garden of the Gods you will find yourself in Old Colorado City - the oldest part of town which used to be not a mining town, but mining supply town with bunch of saloons. The story of that era best represented in the Ghost Town Museum -well thought and put together exhibit .
One of the most popular things to do here is to ride on the Pikes Peak Cog Railway to the summit of Pikes Peak at 14,115 feet. It is half a day adventure where you will have free hour at the summit.
Make sure you go tour United States Air Force Academy (including their infamous Chapel) and Olympic Training Center just east of Colorado Springs downtown. Those tours are free and very educational, but be prepared to do some walking (about a mile total at the Academy and little less at the Olympic Center).
Downtown Colorado Springs is very clean and neat. My favorite place to visit there is Pioneers Museum (it's in the former county court house). Just north of it you will find Fine Art museum, next door is one of the best in the world Money Museum, followed by Colorado College campus with it's unique grounds and architecture. Visiting all these and other places require having a car or some other transportation in town since distances are not short. If you don't have a vehicle, consider hiring Colorado Personal Tour Guide for a few hours or days depending on your budget and time line.
Whatever you choose to do, I promise you will have a great time in Colorado Springs all year around!
