I covered the Glenwood Community Park playground, at the corner of Glenwood and Golf, back when I introduced the Aliso Viejo Aquatic Center. Andrea submitted it as a recommendation recently. Unfortunately, I've been notified that it's a PRIVATE PARK paid for by the Glenwood HOA. Sorry!
According to an HOA member and resident, the playground nearest the pool is a public city park (see photo below).
