Happy Wave is a laid-back Class II park-and-play spot on the Wenatchee River between Leavenworth and Peshastin, about five miles downstream of the Icicle Road access near river mile 21.5. Access runs through private land, but paddleboarders and playboaters who find their way in treat it as a local favorite, especially as spring runoff starts to drop. Around 6,000 cfs and falling is the sweet spot—enough push for a fun little surf without the pushy water further upstream. It's nothing dramatic, just a mellow, welcoming wave that fits its laid-back mountain-town surroundings.
