There is a playground and an indoor swimming pool at the east end of the lake, miniature golf at the south end and a wading pool at the north end. Bicyle lanes on the street around the lake almost make it all the way around. Green Lake tends to be very busy, especially in summer months. With young inexperienced and unpredictable riders it is best to stick to early morning or cloudy days. There has been some rumblings about closing the inner paved path to bicycles because of heavy traffic, but so far no action.
Paved trail follows shoreline, lots of large ships to see.
Trail continues to the Magnolia bridge. Ride to entrance of Burlington Northern Train Yard and there will be an entrance to a fenced trail through the train yard. The train activity is especially fun for kids. The trail doesn't end near any park, but does have access to the Magnolia loop. From the train yard head up 20th Ave, follow signs to Discovery Park.
