Set sail from Sapphire Beach for a private, full-day cruise to St. John National Park. Snorkel vibrant coral gardens, enjoy a grilled lunch and open bar, and customize the route with a small group of up to six guests.
The keel tips, the rigging sings, and the marina slips behind you in a ribbon of memory — Sapphire Beach’s dock office a neat line of pastel buildings and rum-scented taxis. By 9 a.m. the skipper runs through a brief safety talk, hands out snorkel gear, and you climb aboard a clean, comfortable catamaran designed for small private groups. The first breath of open water is saline and bright; the island chain unspools ahead, lazy cays and the serrated silhouette of St. John rising like a green cathedral.

The boat provides shade but not full sun protection; use reef-safe SPF to protect coral and your skin.
If you’re prone to seasickness, take a dose before boarding and sit mid-boat where motion is minimized.
Rocky landings and coral shards at some beaches make water shoes a smart choice for getting in and out.
Carry a small dry bag for phones and keys; the crew has limited storage and saltwater spray is constant.
The US Virgin Islands were once a Danish colony; St. John contains numerous 18th-century plantation ruins now protected within the national park.
Visitors are asked to use reef-safe products and avoid touching coral; operators support low-impact anchoring and National Park regulations to protect reefs.
