We reach a grove of Casuarina trees after a steep hike over slippery red dirt. Casuarina trees look like long-needled pines but are ironwoods, trees with a reputation for strength and durability. The low-hanging braches that graze the ground add to the feeling of protection and shelter. But windows through the thin, knobby leaves lend a sense of playfulness. After a few minutes under this natural cover, we continue on, and up.
