I'm going to be in the Leavenworth area with my family for a few days in mid-April and I'm looking for a place to take my 9 year old son fishing. He's new to fly fishing and while he's caught a number of fish on the fly I'm hoping to find a place that isn't too technical so his beginning casting ability won't be an issue. I know there's a TU kids fishing pond right in town but it doesn't open until July. We've been to Fish Lake in the past and this worked great but ice might be an issue in April. I'm really not to picky about where we go- I just want to provide him with a fun fishing experience. I'm open to lakes, ponds, hike-in lakes, moving waters...- any suggestions would be appreciated. Thanks!
