About us

Established in 2022

From humble beginnings to now, Castle Dome Bouldering has been a labor of love. A small spark to a dream Francis had since 2016. Several years later, that dream has come true and we are happy to share Castle Dome Bouldering with you.

After nine years active duty, Francis-John Rios decided he wanted to continue to serve the community and pursue his passion of opening up a rock climbing gym. Enter Castle Dome Bouldering, a full service gym with bouldering, yoga, fitness, a cafe, and retail store. This wouldn’t be possible without the help of countless people who dared to dream with us, and the many supporters of the community. What once seemed like the tallest mountain is now a 15′ bouldering wall. We will continue to climb and deliver the best experience to those who visit.

We look forward to seeing you SEND!

Francis & Eamon

COMMUNITY

We believe that a community blooms when it grows and works together. We hope you will join us and offer your unique qualities, too.

As the community grows, our goal stays the same: to offer the best possible experience for every person who walks in the door. If you can climb a ladder, you can climb at our gyms.
