Miller Activity Complex

This place is absolutely amazing! First of all, the playground equipment is perfect for all ages. My whole family loves it there! The staff is always friendly and is there to offer a helping hand whenever we need it. In addition, the stairs and zipline activities prove that adults have a blast here as well!

Love love love this place! I have 2 kids, 3&5, and they beg to come weekly for the indoor climbing structure and kiddie pool area. Moms – this place is the best – wifi, comfy seating, kids endlessly play for HOURS & there’s a small tot area too. My go-​to for rainy & snowy days. Both kids have enjoyed bday parties here & we’ve attended 3 more here as well… kids LOVE it! The trampolines are super cool but cost a bit extra to enjoy. Pool area is on the smaller side but plenty of lifeguards to feel comfortable. The outdoor stair climb is the best & kids are surprisingly good at it. Play park is high end but be prepared to chase your kids uphill. Cannot wait for the next phase to open – splash pad & picnic area! Have FUN!
There is an entry fee for the indoor area but it’s less than any lunch out. Bring a pack lunch & snacks and stay a while.

Amazed at all the whining people/​parents comments I’ve read. We have been residents of Castle Rock for a long time. This facility was designed to be completed in stages and as of mid 2016, is absolutely awesome. They now have the main facility (pool, fields, jungle gym, indoor golf, batting cages, etc…), plus tons of outdoor activities (zip lines, play areas, water fountains, epic tower, epic skyfall, etc…) and now an amphitheater and event room. My wife had purchased me a gift certificate for zip lining, so she and just finally used it. Because a large group tried to exceed the group size limit, the managers of the zip line area, Brooke and AJ, took my wife and I on a ‘private’ tour to accommodate the other group. We had the absolute best time with them and also appreciated the fact that they went out of their way to ensure the other group had a great experience as well as us. I can’t say enough good things about the staff and facility and find it funny to see all of the ridiculous complaints. Please come and enjoy now that the weather is turning nice, you won’t regret it.

The pool and kids jungle gym are fun. The field and playground outside are great too. But the family locker room smelled horrible last time we were there. Also paying an extra $ 7 per person for the trampolines when youve already paid an entrance fee is a bit ridiculous. The place is infested with teens/​tweens but they are fairly respectful to the little kids and the parents.

Came here for soccer skills class for my older daughter. Paid 200 for it. Great class. My younger daughter wanted to play on play set. Ok. $ 5.00 ok. Then wanted to go on trampoline they wanted another 7.00 well ok but then said she needed to be with a paying adult. So another 7.00. Yea. Had to draw the line. 14.00 for my daughter to jump on trampoline after paying 5.00 for play area and 200 for soccer. That is a little crazy

Our kids just love it here. With just their interests in mind I give it 5 stars. With my parental concerns I can certainly give it less stars. Recently I cut my hand on a zip tie that had broken. I think the staff and the city needs to read these reviews and really try to address our concerns.

If i could give a negitive star review i would, I am sitting here at the mac in the waiting area outside of the play area. I am not allowed into the comfortable seating or to even watch my kids play in the pool because I wont pay $ 6 to go in and sit. I wont be playing in the pool or play area I wont be doing anything but trying to watch my kids but your rude teenage staff specifically a girl named Kelly who slams paper on the desk when you question her or she gives you dirty looks even trying to use the bathroom state its policy. I found it odd that this center makes parents pay to sita and not do anything but the other rec center doesn’t. I can honestly say I probably will never bring my kids back here again because I would rather go seea staff that a.) Cares about their customers and their safety then deal with someone who thinks shes mighter then god. B.) Someonr who would stay off their cwll phone. Its a job sweetheart learn responsibility. Very unprofessional and im very disappointed
My daughter just came out after ½ hr because I pd for them to get in an said this is the most boring place. She asked to go to the actual rec center instead. Just proves even older kids arent a fan.

Nice hiking place. Steps are a good work out. Not strenuous and something easy to do in a weekend.

Pretty disappointed as a tax payer. High priced and not really anywhere to work out indoors. Just a pool and indoor field. No work out equipment, track or anything! Another poor design by the town. I even asked the front desk what I would get for the $ 820 family pass… well there’s the pool! Really?!

Great place. Don’t be confused by the overprotective parent reviews. Every child I have met loves this place. Some parents don’t love it because they feel paying extra for the trampoline makes no sense. To me it makes perfect sense that can be summarized by two words… liability insurance. My kids love the trampoline and I love the sleepiness inducing qualities (well worth the investment!), but if they just want to swim or play in the play area then I’m not paying for something they do not use.
My kids have literally spent the entire day in the pool there. There is no price tag for them or their parents. Clearly win, win, win.
I do agree the teenage staff at the pool is less than perfect but they will listen when approached. Also the front needs turnstiles to boast exit security and discourage those who decide they don’t need to pay and raise the overall cost for those that do.
Pricing is simple economies of scale. If you are coming more than once, get a punch card. If you are coming more than that, get a family pass.
All the outside activities net of the Zip line and Adventure tower are free.

The entire town was so excited about this place before it opened and I am sadly disappointed. The MAC center currently consists of a turf field, a pool, a trampoline area, and kids play area. Let me start by saying that I am not one of those over protective mothers. I don’t feed my child an only organic diet, I’m not over protective. In fact I feel I am fairly reasonable with my expectations as a mother. Here are my reasons outlining what I think they did wrong when they built it:
1. Security people!!! I have a head strong toddler. The toddler areas is pretty lame so she doesn’t want anything to do with it. She prefers to play in the jungle gym regardless of her size which means i have to play with her because she’s too small to go by herself. Here’s the problem, there is a huge slide that starts on the upper level and ends on the lower level. We never let her play unattended but because of our size difference she often makes it down the slide before I’ve even made it to the slide area. Because the slide ends on a completely different level than the actual jungle gym, and because there is absolutely nothing in place to keep the kids in that area it is very easy for kids to get access to other areas of the building before their parents have a chance to do anything about it. Add to that the multiple exits and it would be very easy for your child to escape the building altogether before you even made it to the other level. Or worse, someone could easily walk out with them. I can’t believe our town wouldn’t consider the safety of our children when building this. It’s so stressful we just don’t even go anymore without at least three people to make sure she is safe. One at the bottom of the slide, one inside and one on the upper level to catch her if she runs. The entire area is unsecured so it’s not like those indoor play places that you can just let them run.
2. The turf field is artificial. My daughter used to do a gymnastics class at the rec center that was moved to the MAC when it opened. Keep in mind this is a toddler class. Ages 12 months to 3 years. Why would you put a bunch of toddlers on an artificial turf field and not expect them to try to eat the little rubber dots? Plus the little rubber dots get into their hair, their ears, their clothes, our shoes, purses, literally every where. Someone wasn’t thinking on that one which is sad because we truly loved the class and the teacher. Let’s not even mention the growing evidence that artificial turf fields cause cancer.
3. Everything is priced separately. If we go to play on the jungle gym it’s one fee, but if we want to jump on the trampolines it’s another fee. Try telling a little kid that they can’t jump on the trampolines when they go down the slide and it deposits them right in from of them! In my case, she was already jumping before I got down the slide and then we were told we had to get off.
4. The pool at the rec center is way better as far as toddler areas go.
5. The staff are rude. The front desk staff need some serious lessons on manners. This comes from multiple interactions with myself, my husband and my daughter.
6. Every time we went to gymnastics it was a fight to leave because she wanted to play on all the equipment which is nickel and dimed. The prices were not reasonable for what you got.
I just really think they could have thought this out better. At least considered the safety of our children in the planning process. I feel like the town council is so busy developing to increase tourism and in turn revenue that they are failing their citizens. The people who currently pay their salaries.

I love that this is in our town. We have kids ages 6, 4, and 2 and they loved it. They allow you to bring in outside food so we packed dinner and met some friends there. We enjoyed the pool and play area. The only down side to our visit was the staff. First off I want to say I think teenagers are awesome, capable humans but tonight the behavior I saw was not of a very high standard. Every trash can in the building was overflowing and the bathrooms needed a good cleaning. There were at 5 workers at the front counter standing around talking and on their phones. For the $ 52 between the two families I think a little more hustle out of the staff would be justified. Million dollar facility + lazy staff = two star review. We will be back if the staff gets some quality leadership I will gladly change this to a five star review.

My whole family really enjoyed this place. I have an almost two year old and he was all about it. He especially loved running around the soccer field they have inside of here. We didn’t go to the pool but walked around and saw how much fun everyone inside was having so next time, that is a must! It’s a safe place + very clean which are two huge concerns I have with any place my babe will be. Kids can be kids here and you don’t feel like you have to helicopter over them to keep them safe. This will be one of our go to places when we are visiting family in Colorado during the colder months!

So sad that so much money went into building a gorgeous complex and then management has created rules that prevent maximum usage of the facility. What a waste. Tweens run wild and loose, but kids under 8 are prevented to do many things even with direct parent supervision. Biggest complaint is a parent must be IN the pool with kids under 8 in a pool that does not exceed 3’6″. Ridiculous rule! And the reason given the front desk staff: lifeguards were having to work too hard. Parents must be IN the tramp pit with children under 8, a.k.a. actively jumping. Would love to know how they accommodate kids who have a parent with physical limitations. Sounds like a lawsuit waiting to happen. For the money you will spend on admission, you could go to a real trampoline park or pool and kids actually get to use the facilities! Will NOT be returning.

There was a lot of hype surrounding this place. The facility is HUGE, however the use of space is not what I thought. It’s a turf field, trampoline area, toddler and kid jungle gym, and then the pool. The toddler area is tiny, the kids jungle gym I thought was pretty impressive, my kids loved it they are 5 and under.
I thought it was a little pricy considering you only get access to the play area and pool. You have to pay extra for the trampoline, batting cages, and turf field, etc and it can get expensive quick when you have 4 kids. Oh, and adults have to pay to go in with them and supervise, which I think is totally lame, I’m not using the facility I’m there to let the kids have fun and make sure they don’t break an arm or something along the way. They have single admissions, and monthly/​semi annual/​annual passes as well that make it slightly less expensive.
They have multiple phases planned in the future which is cool, but I’m assuming you’ll have to pay extra for everything like you do now. I’d appreciate lower costs for residents especially.

I had such high hopes for this place, it seemed like it would be so awesome and I was terribly disappointed. The complex seems massive from the outside but once you get inside you’re wondering how it looks so big when there is absolutely nothing there. You walk in the front door and you can see the kids play area, the indoor field and the trampoline area … and that’s it (with the exception of the pool).
The kids play area seems like it would be pretty amazing for a kid and there were so many kids playing there. I have a 14 month old and he was too little for the main play area so we played in the «babies only» area. There is a small log to crawl through and a little slide with an area to climb up and that’s it. He’s a 1 yr old so he’s not hard to please, but even this dinky play area got boring quickly for him. Also, there were mostly older kids playing in the baby area. I guess the big play area was too boring so they were running around like crazy in the area for kids so plan on your kid getting run over the whole time.
The trampoline area seems cool, but you have to pay extra to use it and when you’ve already paid to be bored in the first 8 minutes of arriving it hardly seems worth it. The pool area looked nice, we didn’t go swimming but the slide looked really fun. And they had a large kid area of the pool with a water table in the middle and a slide on the side. Compared to the old rec center in castle rock I’d say the one at the MAC isn’t nearly as cool.
I think the only purpose of the MAC was to entertain kids up to like age 12. As an adult there was nothing there for me except a pool which wasn’t that great anyways. I thought there was a gym at least, but no. I would save your money and go to a park or use the old rec center, it’s WAY better.
