Red Rocks is definitely worth a visit when in the Morrison area. The concert venue is amazing to see and there are lots of easy hikes around the amphitheater.
The Coors Brewery is a great place to stop by when in Golden! The tour is a self-guided audio tour, only takes about 30-60 minutes and at the end you are rewarded with 3 full size beer samples! Afterwards, we suggest grabbing a bite to eat or a drink in historic downtown Golden.
There are numerous hikes around lookout Mountain that provide great views! The hikes are easy and there are multiple trails and distances. If you're looking to opt outside, this is a great place to go that's near the hotels!
