Four of us are heading to NZ this year, and plan to be hiking part of the Abel Tasman Coastal Track in late November 2012. We are all in good shape so endurance should not be an issue. Currently we are considering taking a water taxi to Bark Bay and following the track back to Marahau. Has anyone done this before and know approximately how long it takes? I've read between 5-6, but many of the water taxi sites say 8 hours. We want to see as much of the park as possible given one day. Any other recommendations are welcome too. Looking forward to responses, and thanks for your input!
