Battery Cave

Tucked into the rocky coastline near Burnham-on-Sea, Battery Cave offers a proper adventure for families willing to get their feet wet. This natural sea cave can only be reached at low tide, making timing absolutely crucial for your visit.

The cave itself isn't enormous, but there's something thrilling about ducking inside a space carved by centuries of waves. Kids will love the echo effect and the sense of exploration, though parents should keep a close eye on little ones as the rocks can be slippery. You'll need decent footwear with grip - flip-flops simply won't cut it.

Check the tide times before setting off from your holiday park, as you'll want at least two hours either side of low tide to explore safely. The walk along the shore from Burnham-on-Sea takes about 20 minutes, and the cave makes a good focal point for a longer coastal ramble.

Families staying at nearby parks like Warren Farm Holiday Centre or Diamond Farm Holiday Park will find this a cracking free day out, especially if combined with rock pooling along the same stretch of coast. Just don't expect underground chambers or stalactites - this is seaside cave exploration at its most basic, but none the worse for it.
