River Run Park

River Run Park (RRP) is a free whitewater park that proves that low flow rivers like the S. Platte can produce fun surfable waves. It might not be a Glenwood Springs wave but the three surfable waves at RRP are a blast and have quickly grown the river surfing scene in Metro Denver. There are six drops but only three surfable waves that two are adjustable real time and one that is adjusted as needed off season. RRP is minutes south of Denver.


RRP starts producing surfable waves at 80 CFS +/- and can handle over a thousand cfs on one of the waves. Best flow to surf are as follows. "CHICLETS WAVE": First RRP drop located next to the pedestrian bridge at the main park area, named after blocks that look like chiclets gum from above on the bridge. Chiclets comes in at about 100cfs and can handle up to about 350cfs. Is a good beginners wave. "BENIHANA'S WAVE": 2nd RRP wave going up stream and is named after Ben Nielsen, the main design engineer for RRP, and for the famous skateboard trick of the same name. This wave is a 'WaveShapper' and is adjusted realtime to make the wave more surfable with 3 hydraulic flaps. Wave comes in at 180cfs but is only adjusted when flow is 200cfs. The wave's top end of flow is unknown but has been surfed at over 1,200cfs. Benihana's is a novice wave to expert wave. Learn Chiclets first and hit Benni's. "NIKKI’s" aka "WAVE SIXX": Is the sixth wave counting drops going up stream from Chiclets. It is about a 10 minute walk up the bike path (watch out for cyclists) and is at the solar panel that operates the 'WaveShaper' adjustable flap. Sixx can be surfed at insanely low flows but really comes in at 130cfs and tops out at 350cfs+/-. Currently the wave has to be approved by the WaveShaper volunteers to be surfed so keep an eye on the surf reports. Nikki's/Sixx is novice to expert wave because it is a steep fast wave that is similar to a sheet wave. Watch some locals on how to surf Nikki's/Sixx and bring a very short board. NOTE: Be cool and thankful to the WaveShaper volunteers who take time from their day during the season to shape Benihanas and Sixx. MORE INFO AT http://endlesswaves.net/waves/river-run-park/

Season 2020 did not produce much water though Wave Sixx showed that starting at about 250cfs it is game on!!! As an example is this June 2020 pic of Micheal Deeble getting after it on his old softtop board. You should see him ride a regular hard board on this wave.

Thomas family showing how a family truly "stays together when they surf together"... 2019 was a stellar water flow season and Chiclets wave proved to be a good wave to surf.

Eric Halborg (Dragondeer band frontman) ripping it up on Benihana's under the tiki's approval and a lineup of surfers and kayakers... The tiki later floated away but will be back one day soon.

April 10th, 2021 Chiclets being surfed on a high volume board and shorty wetsuit. Probably better to have a full suit at the least... Also the bathrooms at RRP have been re-opened! Season is about to get going!!!

Not surfable but a micro-wave was showing at Chiclets with prior Friday's Chatfield release of 60cfs (why and for how long?). Note, the restrooms are closed due to vandalism and they need to be re-opened for surf season and summer!
