Lake Coeur d'Alene Swim on one Coeur d'Alene's long public beach, or travel to other parts of the lake. There is also a parasaling business in CD'A. The Lake is also very good for watersports such as skiing or wakeboarding.
Silverwood Theme Park The park is located a short drive north of Coeur d'Alene. Awesome place for the kids - great rides for all ages. Or visit the adjacent Boulder Beach waterpark. You can easily spend 2 days here at the two parks.
The CD'A Brewing Company is an outstanding microbrewery / restaurant with the unusual situation, great beers brewed on-site AND great food. The restaurant is a few blocks up from the lake and in the middle of several art galleries. Great for families and a beer on the late summer nights (its still light up here in the summer until about 10:30 PM!)
Coeur d'Alene Brewpub - Good brews crafted onsite. Pool and jukebox. Kegs, cases, 6-packs and growlers available. 2nd and Lakeside, downtown. Stumbling distance to the Lake beach, coffee shops, burger joints, post office, and most of the CdA downtown area.
The Coeur d'Alene Resort Located on the lake, in the middle of downtown, the CDA Resort also has a golf course with a "Floating Green" and a Marina.
