The Reef Bay Trail on St. John drops 2.2 miles through dense tropical forest before opening onto a freshwater pool where roughly 20 carvings — stylized human faces with oval eyes, spirals, and geometric shapes — stare out from the volcanic rock just above the waterline. Archaeologists date these petroglyphs to between 500 and 1500 CE, placing them within the Ostionoid and Taino periods of Caribbean pre-Columbian history. This article walks you through what the carvings actually are, who made them, the leading theories about their purpose, and exactly how to visit them from the British Virgin Islands.
Twenty carved faces and spirals etched into volcanic rock beside a freshwater pool — the most concentrated collection of Taino petroglyphs in the Virgin Islands, reached only by a 2.2-mile hike through the Reef Bay Valley.

The St. John Petroglyphs: What You’re Actually Looking At
The carvings sit at the edge of a small reflecting pool deep in the jungle of St. John, part of the U.S. Virgin Islands but reachable by a short ferry from Tortola in the BVI. Some figures sit high on the rock face, others low near the waterline. All were made using sharpened stone or coral tools — no metal, no modern instruments. When the pool is calm, the carved faces mirror back on the water’s surface, an effect that may have been intentional for the Taino who created them.
Archaeologists believe the site was never a place for everyday life. Surveys found no domestic structures nearby — no pottery shards from cooking or tools from daily tasks. Instead, the evidence points to sacred rites or seasonal gatherings. Pottery fragments and tools unearthed during surveys in the 1980s confirmed the area’s ceremonial importance rather than residential use.
Who Made the Petroglyphs — and When
The Taino were part of the larger Arawakan-speaking groups that migrated from South America into the Caribbean. By the time Columbus arrived in 1493, they had long settled the Virgin Islands, Puerto Rico, and the Greater Antilles. Their spirituality centered on zemis — gods, spirits, and ancestral figures connected to nature — which they honored through rituals, carvings, and offerings. The St. John petroglyphs are widely believed to be connected to this belief system.
The carvings were formally documented in 1933 by Danish archaeologist Gudmund Hatt, who published photos and descriptions for the Danish National Museum. Earlier, the carvings were likely known to enslaved Africans and laborers working the Reef Bay sugar plantations in the 18th and 19th centuries. More serious archaeological surveys began in the 1980s under the University of the Virgin Islands and the National Park Service, which unearthed Taino-era pottery shards and tools nearby.
Stylistic similarities tie the St. John carvings to other Taino sites. The faces and spiral forms match carvings at Cueva del Indio in Puerto Rico and Los Haitises National Park in the Dominican Republic. Water and stone were central to Taino spiritual rituals, and the reflective pool here fits descriptions in early Spanish writings of Taino ceremonial places. Some scholars believe the site may have been a ceremonial pilgrimage destination, a fertility shrine, or a place of initiation rites.

The Leading Theories — Spiritual Signposts, Ancestors, or Something Else
Academic interpretations vary. The leading theory holds that the petroglyphs were spiritual signposts marking a place of transition — between life and death, water and sky, spirit and earth. Water was thought to be a bridge between worlds for the Taino, and the pool’s glassy surface with surrounding cliffs fits that description.
Some of the spirals resemble known symbols for wind and water, tying the site to elemental worship. Other theories suggest ancestor veneration, ritual communication with zemis, status symbols for initiated elite, or even star maps and sacred geography. No single interpretation has universal agreement, but the concentration of carvings at a reflective water source is consistent across the leading hypotheses.
A more speculative fringe theory suggests the carvings resemble the classic “gray alien” image — hollow eyes, simplified features — and that the pool’s mirror-like reflection could represent an ancient portal or contact site. Spiral designs have been interpreted by some as solar systems, wormholes, or celestial maps. No hard evidence supports these claims, but the site continues to attract visitors who describe the energy as “charged” and note an “unnerving stillness” at the pool.
Reaching the Petroglyphs: The Reef Bay Trail Hike
The only way to see the petroglyphs is on foot. The Reef Bay Trail starts from Centerline Road on St. John and descends 2.2 miles through the forest. You’ll pass the ruins of a Danish sugar mill, towering kapok and turpentine trees, and wildlife including deer, bananaquits, and land crabs. A quiet spur trail branches off to the pool where the stone-carved faces watch.
Take the ferry from Tortola (BVI) to Cruz Bay, St. John. Ferries run multiple times daily. From Cruz Bay, you’ll need a taxi or rental car to reach the trailhead on Centerline Road — about 20 minutes drive. Check current ferry schedules on the NPS site before planning your day.
The trail descends 2.2 miles through dense forest. Start early — the heat builds fast, and the hike takes longer than the distance suggests. Bring at least 1 liter of water per person, sunscreen, and insect repellent. The trail is well-maintained but includes rocky sections and roots. Check trail conditions on the NPS page before you go.
Just before the trail ends at Reef Bay, a marked spur leads to the petroglyph pool. The carvings sit at the water’s edge — don’t step into the pool itself. The site is small; expect to share it with a few other hikers. Allow 20–30 minutes to sit and observe the carvings and the reflections.
The return hike is 2.2 miles uphill — the steepest part of the day. Alternatively, you can arrange a boat pickup at Reef Bay beach through a local charter service, which avoids the uphill return. NPS recommends checking ranger-led hike options that sometimes include boat return.
Start the Reef Bay Trail by 8 a.m. — the pool is shaded in the morning, and the carvings catch the best light for photos before noon. By midday, the sun hits the rock face directly and washes out the detail in the carvings.
Other Taino Petroglyph Sites Worth Visiting in the Region
The St. John petroglyphs are the most accessible concentration in the Virgin Islands, but the Taino left carvings across the Caribbean. If you’re basing yourself in the BVI and want to explore further, three sites stand out:
Cueva del Indio in Puerto Rico — about an hour’s drive from San Juan — holds petroglyphs carved into limestone cave walls, with similar face and spiral designs. Cueva Clara de Camuy, also in Puerto Rico, is a massive cave system where Taino carvings appear alongside stalactites and stalagmites. Los Haitises National Park in the Dominican Republic contains cave art spread across mangrove islands, accessible only by boat. Each site offers a different window into the spiritual world the Taino carved directly into stone.
Getting There from the BVI: Logistics and Planning
The St. John petroglyphs are in the U.S. Virgin Islands, not the BVI, but the crossing from Tortola is straightforward. Ferries run from Tortola to Cruz Bay, St. John, multiple times daily — the ride takes about 30 minutes. You’ll need a passport and go through U.S. Customs on arrival. Once in Cruz Bay, taxis and rental cars are available to reach the Reef Bay trailhead on Centerline Road.
The hike itself requires no permit, but the trail is in Virgin Islands National Park, which charges no entry fee. The ranger-led hike offered by the National Park Service includes a boat return and interpretive information about the petroglyphs — check the NPS calendar for scheduled dates.
The hike back up from the petroglyphs is 2.2 miles uphill with no shade in the middle section. Hikers regularly underestimate this return. If you’re visiting with young children or anyone with limited mobility, arrange a boat pickup from Reef Bay beach in advance — several local charter companies offer this service.
For those who prefer a guided experience, guided walking tours of the BVI and USVI available on Viator can help you coordinate the ferry crossing and hike logistics in a single booking.

Before You Go to the Reef Bay Petroglyphs
Is the hike suitable for kids?
The 4.4-mile round trip with 500+ feet of elevation gain on the return is manageable for active kids 8 and older. Bring extra water and snacks — there are no facilities on the trail. The sugar mill ruins midway make a good rest stop.
Can I visit without hiking?
No — the petroglyphs are only accessible on foot via the Reef Bay Trail or by hiking down with a ranger-led group that includes a boat pickup from Reef Bay beach. There is no road access to the pool.
How long should I budget for the whole trip from BVI?
Plan for a full day: 30-minute ferry each way, 20-minute taxi to the trailhead, 2–3 hours hiking, and 30–45 minutes at the pool. Add buffer for customs on the way back to Tortola.
Are the petroglyphs protected?
Yes — the site is within Virgin Islands National Park. Touching the carvings is discouraged, and stepping into the pool is not permitted. The NPS maintains the trail and monitors the site.
What’s the best time of year to visit?
December through April offers the driest weather and most stable trail conditions. Summer afternoons bring frequent rain that can make the trail slippery, and the heat makes the uphill return harder.
Stone That Holds a Story
The Reef Bay petroglyphs survive because of where they sit — remote, forested, and quiet. The Taino chose that spot deliberately, and the same remoteness that preserved the carvings for centuries makes them a genuine effort to reach today. For anyone willing to make the crossing from Tortola and put in the hike, the reward is a direct encounter with a civilization that left its mark not in buildings or books, but in volcanic rock beside a pool that still reflects the faces they carved.
