The Ritz-Carlton Key Biscayne
A barrier-island retreat with quick water access to Biscayne Bay. Use nearby marinas for launch and dockage, then cruise to Stiltsville, Boca Chita Key, and Cape Florida.
The Ritz-Carlton Key Biscayne, Miami is a polished, resort-style base just offshore from downtown Miami—ideal for travelers who want a calmer shoreline while staying close to Biscayne Bay’s best boating.
Located on Grand Bay Drive on Key Biscayne, this resort pairs beach-and-spa downtime with easy routes to sandbars, island stops, and national-park scenery. While on-property boat slips aren’t clearly documented, boaters typically stage from nearby marinas on Key Biscayne and Coconut Grove.
The resort completed a major ~$100M transformation and reopened in December 2025, so it’s smart to confirm current outlet hours and amenity details when booking—especially if you’re timing your stay around a boating itinerary.

Day 2: Biscayne Bay icons (Stiltsville + Boca Chita Key)
- Morning departure for a sightseeing pass by Stiltsville’s historic bay houses.
- Continue to Boca Chita Key for a classic Biscayne National Park island stop—plan for swimming, beach time, and photos.
- Return before late afternoon; rinse gear and reset for the next day.
Day 3: Cape Florida / No Name Harbor day
- Cruise toward the Key Biscayne tip for Bill Baggs Cape Florida State Park and the No Name Harbor area.
- Review posted anchoring and overnight rules/fees before you go, and follow local guidance on where to hold.

- Keep one day open for tides, wind, and marina availability.
- Use Dinner Key Marina as a staging alternative if Key Biscayne docks are tight.
Key Biscayne feels like a true resort escape, but you’re still minutes from Biscayne Bay. We docked nearby, spent the day at Stiltsville and Boca Chita, and were back for dinner without any hassle.
