One of the worst-kept secrets near Kilauea on the North Shore of Kauai is Secrets Beach. It's a long, treacherous hike down to the beach, but it's well worth it.
Most of the property above Secrets Beach is private and owned by multi-millionaires (if not billionaires!). Emily cleans at one of the houses where several celebrities have stayed (although I'm not allowed to disclose which ones). I found some trails that had not been used in a long while and explored up the hills as much as I dared without disturbing those in their McMansions. Quite idyllic.
Next I went around to the left to explore up on the rocks to see if I could make it around to the Secret Lava Pools. No luck this time, with the tide well in and the surf fairly strong.
