Nolte State Park

Nolte State Park at the base of the Cascade Foothills offers a beautiful, rural landscape.

Black Diamond Triathlon will include a Super Sprint, Sprint and Olympic in 2018.  Enjoy a swim in Deep Lake, bike on gently rolling hills with generous shoulders and a trail run for the Super Sprint/Sprint and road and trail for the Olympic.

Families can enjoy a beautiful park during the day with a swim beach, kids play area (accessible for kids!), and generous picnic area as their athletes come and go through transition.  After the race, everyone can enjoy a full meal, finishers medal, and an awards celebration that awards the top 5 in each age group Sprint and Olympic, top 3 in the Super Sprint, top 3 relays and the top 3 overall men and women. 

Nolte State Park is open to the public from dawn until dusk - you are more than welcome to visit the park anytime.   There is no lifeguard but swimming is always permitted at your own risk. There are no overnight accommodations.  ​
