Crossing the Darien gap was a pleasure. Sure getting to this point was a touch stressful at times, but the actual voyage was a delight. Getting the bikes OFF the boat, however, was another story.
Crossing the Darien Gap isn't easy. There's no road, (I double checked) so you can't ride, thus the options are to fly or to sail. Flying costs about 700$ per bike, plus whatever it costs for you. There are many sailboats that take bikes, but they cost over 1000$. Each. To travel about 200 nautical miles.
