About us
Welcome to Sender One Climbing!
At Sender One, our purpose is to help people discover themselves and connect with others through climbing. From your very first climb to your biggest challenge, our spaces are built to inspire, encourage, and bring people together.
This Meetup group is where you'll find climbing events, community gatherings, competitions, clinics, and social experiences hosted by Sender One across Southern California. Whether you're brand new to climbing or a longtime member of the climbing community, you'll find opportunities to challenge yourself, learn something new, and connect with others who share a passion for movement and adventure.
We welcome climbers of all backgrounds, experience levels, and identities. Our goal is to create an inclusive, supportive community where everyone feels empowered to grow, explore, and belong.
Join us for climbing, connection, and community—we can't wait to meet you.
Let's send together.
