Places to Stay in Cornwall

🏰 A) Merlin’s Cave, Tintagel

Beneath the dramatic ruins of Tintagel Castle, Merlin’s Cave stretches into the sea—a hollow echo chamber of crashing waves and ancient lore. At low tide, step inside and imagine the wizard’s whisper riding the spray. Arthurian mythology hangs thick in the air here.

💡 Top Tip: Time your visit with a falling tide to access the cave and catch epic shots of the sunlight cutting through sea mist.

🌿 B) St Nectan’s Glen, near Tintagel

Follow a serene woodland walk to uncover St Nectan’s Glen, where a cascading 60-foot waterfall pours through a natural rock arch. While the glen isn’t a traditional cave, nearby crevices and mossy alcoves combined with local hermit legends make it feel enchantingly off-world.

🌀 C) Holywell Cave, Holywell Bay

Hidden in the cliffs and only accessible at low tide, this multi-chambered tidal cave contains natural rock basins once thought to have healing powers. Its secluded location and rock-sculpted pools make it feel like nature’s secret spa.

👣 Adventure Hint: Bring waterproof shoes—it can get slippery inside, especially if you’re chasing the glow of an incoming tide.

💔 D) Crantock Cave, near Newquay

This romantic yet eerie sea cave is etched with a tragic 18th-century love poem carved into the rock. Legend says it commemorates a woman who perished while waiting for her lover’s return. Reach it on foot during a coastal walk from Crantock Beach.

🎧 Optional: Create a themed playlist or audio companion with local stories to enhance the experience.

🌊 E) Song of the Sea Cave, Nanjizal

Tucked near Land’s End, this remote wonder—also called Zawn Pyg—is a visual marvel. The natural rock arch and crystal-clear turquoise waters feel more Mediterranean than Cornish. It’s a reward for those who make the coastal trek to find it.

🚶 Note: No direct parking; access is on foot from nearby trails. Best visited at low tide.

🎶 F) Carnglaze Caverns, near Liskeard

Step underground into the depths of former slate mines, now transformed into cathedral-like caverns with reflective subterranean lakes. Carnglaze offers guided tours by torchlight and even hosts underground concerts—a surreal acoustic experience you won’t forget.

🎟️ Don’t Miss: The crystal cavern shop and woodland garden trails just above ground.
