The Ala Mauka Makai Trail at Kaloko-Honokohau National Historic Park
A quick 1.5 mile out-and-back trail north of Kona. Hike across the lava fields down to the beach, where you're likely to see turtles. Bring water and sun protection.
The Kona coast is sunny, dry, and comfortably stays between 65°F and 89°F: the perfect weather for water sports, hiking, and a variety of other adventures.
