Castle Rock is a picturesque foothills town with a walkable historic downtown, local breweries and restaurants, and immediate access to dozens of hiking and biking trails around the iconic rock formation — cozy, outdoorsy, and lively enough to make multi-week stays feel like a proper getaway.
Big-city options are close by: Denver (≈30 miles) and Colorado Springs (≈40 miles) provide major hospitals, museums, nightlife, and airports when you want more variety.
