We are planning a trip to Chile in April and are trying to figure out some logistics of getting in and out of TdP. We've read that there's a boat that takes you to Puerto Natales by going down the Rio Serrano and Seno Ultima Esperanza. So far though, we've only seen this offered as a round trip.
Our question is - can we take this boat one way (from TdP to Natales)? If so, we're interested in learning more about price, departure times, length of ride, etc.
Any advice will be appreciated. Thanks very much :)
