Named after James Stephen — a British abolitionist who fought to end the slave trade — this two-part hike sets off from the foot of Olivees Mountain and plunges into the rainforest. Climb up 1,339 feet, past the cave along the marked trail, until you reach two waterfalls. From here, the choice is yours: Turn back or tackle an advanced hike, complete with scrambling, rope climbing, and rock hopping, to reach the second cascade. Whichever option you choose, you’ll be back at base camp within five hours.
