Whohoo, so much enjoyable stuff in one place! Yankee Doodle Lake is excellent! You can catch a glimpse of Guinn Mountain from Yankee Doodle Lake, and the snow is wonderful at Eldora. Yankee Doodle Lake is one of the lakes here in the Front Range. If you like skiing, you're in luck; Winter Park is near Yankee Doodle Lake; hiking along the Devils Thumb Trail is splendid fun. An out of the ordinary thing to stop by near Yankee Doodle Lake is Skyscraper Dam.
For all you boaters, Beacon Landing Marina is a good marina close by. Take a hike on the Guinn Mountain Ski Trail, and camping at Buckingham Campground is always a splendid experience.
