You can easily combine two of our recommended excursions for a full day of activity. Or visit one San Juan attraction and then slip away to a city resort beach or Luquillo Beach for a lazy afternoon. Route 30 west to Caguas, where you meet expressway Route 52 to San Juan. After rush hour, this drive is about 45 minutes. Then, take mountain Route 185 north to Route 3 west.
All routes are visually interesting.
During weekday rush hour periods it's best to stay off the expressway in San Juan. Expressway Route 30 west to Caguas, where you meet expressway Route 52 to San Juan. Continue on 53 until it becomes Route 18 and then Route 22. Exit on Route 25 or just past it on Route 26. Travel west until both become Route 25.
