Blowing Rocks Jupiter FL

Blowing Rocks Preserve

One of the most dramatic shorelines in Florida, the rocky shore of Blowing Rocks Preserve has sea caves and bluffs to explore on a hike through the oceanfront preserve

Jupiter      ( 26.978967, -80.084017 )      2.5 miles

983shares
West side and visitor center closed for public safety

Stretching more than a mile along Jupiter Island, a tall limestone terrace dominates the meeting of sand and sea, the longest and most dramatic stretch of rocky shoreline in Florida.

Preserved by local residents in 1969 and turned over to The Nature Conservancy, the Blowing Rocks Preserve protects 73 acres of Jupiter Island, from the namesake rocks to sensitive estuarine habitats, mangroves, tropical and oak hammocks, and the beach dunes.

Blowing Rocks rocky shoreline

Check the tide schedule in advance of your visit to ensure you see what you want to see: sea caves at low tide, frothing blowholes at high tide when the seas are rough.


Directions

 
From Interstate 95 or Florida’s Turnpike, exit at Jupiter (Indiantown Rd). Follow Indiantown Rd. east to US 1. Turn north on US 1 to Jupiter Inlet. After crossing the bridge, turn right on South Beach Road (CR 707). Two miles later, watch for the Blowing Rocks Preserve sign on the right. The parking lot is a half mile farther ahead on the right.

Hike

A tangled bower of sea grapes shades the sandy interpretive trail that leads away from the payment kiosk and towards the sea.

Pause to examine the odd peeling bark of a towering gumbo limbo tree, its reddish-brown exterior reminiscent of a tourist with a bad sunburn.

Interpretive sign for Dune Trail The Dune Trail follows the old route of A1A


Along the Dune Trail leading to the beach, sea grapes form a long green tunnel, surprising visitors with their ivory blooms in summer and edible grapes that turn to red in autumn.

There are a few places where you can peer out from the shade of the sea grapes and look out over the dramatic coastline.

Tunnel under sea grape boughs The sea grape tunnel is a special highlight of this hike


As you emerge onto the beach, the aquamarine waters of the Atlantic Ocean beckon, edged with the eroded rocks of the Anastasia limestone formation.

For maximum enjoyment, time your visit to be during low tide, so you can take the time to explore the sea caves carved out of the shore. Over time, some we once visited have crumbled and are only ledges now.

Fallen rock ledge A fallen cave roof along the shoreline


If the tide is low, walk south along the beach, around fallen rocks and in and out of caves, as waves strike stone. It’s a natural labyrinth with a stunning view of the sea.

Some of the caves are tall enough to stand in, with natural benches formed by the erosive power of the tides. Virtually all have natural chimneys exposing the sky above.

Coquina rock facing the sea Along the rock face where a cave roof and chimney eroded away


Peer into the tidal pools to see the keyhole limpet moving slowly across the bottom. Watch for sea urchins tucked into nooks and crannies.

Scurrying like a cockroach, the armored rough-girdled chiton climbs the walls of the caves.

When you reach the end of the caves, you’ve reached the southern end of the preserve.

Climb up and around to the beach, taking care as you walk across jagged limestone emerging from the sand.

Continue north along the beach to return to the dune crossover. As you walk, notice the unusual erosion of the rock surface below.

There are twisted stalactites, stalagmites, and columns in the weathered rock, looking like a miniature version of an underground cave turned inside out.

Blowhole Blowing Rocks Looking through an eroded blowhole


The reddish-black hue to the rock comes from iron deposits in the limestone.

On rough and stormy days, particularly in winter, waves burst through the caves and explode as high as fifty feet in the air.

Sea turtle tracks Sea turtle tracks into the surf


Notice the small roped-off areas. These indicate the locations of sea turtle nests flagged by volunteers.

More than 600 sea turtles nest along this shoreline in summer, clambering over the rocks at high tide to lay their eggs in the soft sand above.

To continue your walk, exit through the jungle of sea grapes and take one last sweeping look across the oceanfront, if you didn’t stop at this overlook on the way in.

Cross the road to the Hawley Environmental Center to continue the hike. If the center is open, pop in. It has interpretive exhibits regarding the habitats protected by the preserve, as well as restrooms and a small gift shop.

When you exit the center, follow the porch around to the south side of the building. A set of stairs leads down to the Restoration Trail along the Indian River Lagoon.

Walking past identified plantings of Jamaican caper, pigeon-plum, and indigoberry, and other tropical hammock plants, you smell the distinctive skunk odor of white stopper on the salt breeze. A set of benches sits in the shade of a gumbo limbo tree.

Passing a gnarled strangler fig, you emerge at the edge of the Indian River Lagoon. Across the lagoon, virtually every parcel of land is developed.

But on this side, Blowing Rocks Preserve protects a mile of coastline, sheltering pristine beaches lined with mangroves and buttonwood, a monumental effort of removing exotic species and replacing them with natives.

Keep to the right at the junctions to walk along the mangrove fringe. Reaching a mangrove-lined beach, the trail turns sharply left.

At the T intersection, turn left again to return through the regenerating coastal scrub.

Restoration Trail vegetation Vegetation edging the Restoration Trail


Wild balsam apple cascades over pigeon plum, its orange seed pods dangling like Christmas ornaments. Fragrant wildflower aromas fill the air as you approach a trail junction. Turn right.

Mounds of moonflower and wild balsam apple vines cover the sea grapes and saw palmetto. Passing a bench after half a mile, the trail completes its loop, reaching the incoming trail at a junction.

Turn left and go straight across to walk along the lagoon back to the environmental center.
