Los Alamos County brings back High Mountain Mudfest volleyball tournament
Teams have until July 8 to sign up for High Mountain Mudfest at North Mesa Park, with adults $130 and teens able to enter for $5 as individuals. Spectators get in free.

Los Alamos County is bringing back High Mountain Mudfest at North Mesa Park, with adult play set for July 11 at 8:30 a.m. and teen competition following July 12 at 8:30 a.m. The mud volleyball tournament is open to co-ed competitive teams of six to 12 players, and the county says a minimum of four teams is needed for the event to go forward.
Adult players must be 18 or older, and each adult team must include at least three women and three men. Adult entry is $130 per team. Teen teams are open to players ages 12 to 17, also co-ed and with at least three girls and three boys on each roster. Teen teams cost $30, while individual teen registrants can enter for $5 and be placed on a team at random, a setup that gives families a way to participate even if they do not already have a full roster.
Registration closes July 8. The county says sign-ups can be completed online or in person at the Los Alamos County Walk-up Aquatic Center, and the registration forms direct checks to Los Alamos County. Both the adult and youth forms list payment due by July 7, 2026. The youth form also requires players and parents or guardians to complete and sign the roster before play.

Spectators will not have to pay to watch. That free admission matters for a county event built around bringing people to North Mesa Park, not just filling brackets. The park setting ties the tournament to one of Los Alamos’s busiest recreation areas, where the North Mesa planning transcript places the old volleyball areas alongside soccer fields, the dog park, playground, tennis courts and the trailhead.
The county is also leaning into the practical, muddy reality of the sport. Footwear is required, and the event materials say duct tape is highly recommended to help keep shoes on during play. The adult registration form also includes safety and liability language, along with permission for the county to use photos and recordings for marketing purposes.
For questions, the Los Alamos County Recreation Division lists 505-662-8170. In keeping the tournament local, the county is using North Mesa Park as both a sports venue and a summer gathering place, while giving adults and teens a low-cost way to stay active without leaving Los Alamos.
