What our reviewers liked and didn't
Acadia National Park
- Dramatic juxtaposition of granite summits plunging directly into the Atlantic Ocean
- Forty-five miles of car-free, perfectly graded crushed stone carriage roads
- Fare-free Island Explorer shuttle system connects major trailheads reliably
- Exposed, non-technical iron-rung routes provide rare East Coast scrambling
- Intense July crowding causes gridlock and fills major trailheads by 8:00 AM
- Dense sea fog can abruptly obscure summit panoramas and coastal views
- Atlantic water temperatures rarely crack sixty degrees, limiting casual ocean swimming
Boundary Waters
- Warm lake temperatures allow comfortable swimming after grueling overland portages
- Abundant wild blueberries and raspberries ripen directly along sunny portage paths
- World-class freshwater fishing for walleye, smallmouth bass, and northern pike
- Expansive human-powered territory entirely free of motorized craft in most zones
- Intense mosquito and biting fly activity along portages and forested shorelines
- Popular entry routes and island campsites face heavy competition in midsummer
- Severe afternoon thunderstorms present sudden wind and lightning dangers on open lakes
