Isaac Bay BeachU.S. Virgin Islands Beach Guide
Wild white sand and turquoise water, earned by the hike
About
Isaac Bay Beach sits at the far eastern tip of Saint Croix, US Virgin Islands — one of the most remote stretches of shoreline on the island. Roughly 771 metres of white sand curve along water that runs a clear, vivid turquoise, the kind of colour that stops you mid-step on the trail down. There are no facilities, no vendors, no development of any kind — just the beach, the sea, and the wind off the Atlantic. Sea turtles nest here, and the land around it is protected as part of the Jack and Isaac Bay Preserve. The vibe is unambiguously wild.
How to get there
Isaac Bay is hike-in only — there is no road access and no parking. Make your way to the Point Udall trailhead and follow the trail down to the beach; the walk takes around 20 minutes. There is no entry fee documented for the beach itself, but come prepared: no services exist once you leave the trailhead.
Who it's for
For couples
The 20-minute hike in acts as a natural filter, meaning you'll often have long stretches of white sand and turquoise water almost entirely to yourselves — a rare thing in the Caribbean.
For families
Older children who can manage the 20-minute hike will find the turtle nesting site and the protected preserve genuinely fascinating, but the lack of facilities and the remote setting mean this is not suited to very young children or anyone who needs on-site support.
Our take
Isaac Bay is the kind of beach that requires something from you before it gives anything back — and that 20-minute hike from Point Udall is exactly the right price of admission. The white sand and turquoise water are the real thing, and the complete absence of development means you experience them without mediation. Sea turtle nesting here is not a marketing line; it is a genuine ecological event, and the Jack and Isaac Bay Preserve exists to protect it — treat the beach accordingly. Swim with care: there is no lifeguard, no rescue infrastructure, and no one nearby if conditions turn. Come in the dry season, November through April, for the most dependable weather and trail conditions. This is not a beach for a lazy afternoon drive-up — it rewards the prepared and the patient.
What to do
The Jack and Isaac Bay Preserve, just 0.5 km from the beach, is the ecological heart of this corner of Saint Croix and worth exploring before or after your swim. Point Udall, only 0.7 km away, is the trailhead — worth pausing at for the view before you descend. If you have more time on Saint Croix, Buck Island Beach is a well-known destination roughly 7 km away and makes a natural companion trip to round out a day on the east end.
The sweep of white sand against turquoise water shot from the lower end of the trail — just before you step onto the beach — gives you the full bay in one frame with no infrastructure in sight.
The waterline itself, with the undeveloped east-end headland as a backdrop, works especially well in the soft light of early morning. If you time a visit during turtle nesting season, the tracks left in the sand at dawn are a striking and ecologically meaningful subject.
Where to eat
There are no restaurants at Isaac Bay — pack your own food and water before you set out. The closest option after the hike is Carina Café, about 3.6 km away, serving burgers, sandwiches, salads, wings, and pizza. Starlight Lounge is a similar distance at 3.7 km, and Bluewater Terrace is a short drive further at 5.1 km.
Where to stay
The nearest places to stay cluster a few kilometres from the east end. Sapala.Fun is the closest at 1.7 km, followed by Grapetree Bay Hotel & Villas and Hidden Valley Villa, both around 2.1 km away. If you want a fuller resort experience, Carina Bay All-Inclusive Resort & Casino and Oceans at Carina Bay are both roughly 3.8 km from the beach.
Photography
The best light hits the white sand and turquoise water in the early morning, when the beach is at its most empty.
Good to know
Because this is an undeveloped, remote beach with no lifeguard presence, swim with real caution — assess conditions carefully before entering the water. Sea turtle nesting activity means you must stay well clear of any nests or hatchlings and avoid disturbing the sand above the high-tide line after dark. The dry season runs November through April and delivers the most reliable, comfortable conditions for the hike and the beach; the wet season from May through October brings heat, humidity, and the possibility of tropical weather. Bring everything you need — water, food, sun protection — because there is nothing on-site.
