Trail shared by Nick Wilder

Rugged, exposed, historic lava flow route.

Runner Notes

Very unique, but terrible running conditions: loose cobbles of lava and pure sun on black lava.

Description

This trail traverses the last lava flow on Maui, in 1790. The trail has been used for hundreds of years - imagine Hawaiians running barefoot along these razor-sharp, ankle-rolling lava cobbles! The trail was rebuilt in 1824-1840, which makes even the "new" version pretty historic.

The trail itself is miserable - straight across black, hot rock, far from the sea (hot!) and the surface is baseball-sizes lava rocks that seem to move with every step. But the destinations are pretty amazing: especially the turnoff to Keawanaku Beach, which has some of the finest swimming and snorkeling on the entire island, and you are very likely to have it to yourself.

You can continue on for many miles, but the surface is rough-going and once you past the end marked here, you've seen the high points. Definitely not recommended to continue.

Flora & Fauna

The lava is so fresh, you will find very little life, except in the sea, where it is tremendous!

The hot, black highway to Kanaio Beach.  Pretty much like this the whole way... exposed, loose lava.

That's about as much vegetation as you'll find on the King's Highway!
