Avestix Frontier
in Europe

Four voyages a year. Four of the continent's great rivers. One community.

Each quarter, Avestix Frontier charters Transcend Connect to a different corner of Europe — the Rhine, the Moselle, the Dutch waterways, and the Christmas-market route. The destinations change with the seasons; the principals, the privacy, and the purpose remain the same.

Custom Destinations

Fully customisable voyages, designed around your community.

Every Avestix Frontier voyage is unique. Explore traditional routes or uncover hidden gems — a leisurely round-trip through under-touristed towns, tandem cruising, or extended stays in a single iconic city. You decide how many experiences to offer, on your own or curated by Avestix, and every onboard programme is tailored to the families aboard.

Transcend Connect transforms previously static events into flowing programmes that blend leisure and working sessions into your ideal voyage — whether an itinerary never sailed before, or an icon like the Christmas Markets or Tulips in the Netherlands.
