There are no marinas
in the Galapagos
. You are very restricted on what you can do and where you can go on a cruising boat. The anchorage/mooring field in San Cristobol is decent. The anchorage in Isabela is good. Santa Cruz
is overcrowded and rolly. Anywhere you stay, you will be restricted on where you can go in the water
or in land without a national park guide. There are good tours available for varying prices everywhere. Isabela is the most interesting. Great tour to the tunnels and good hikes up the volcano, etc.
If you really want to see the Galapagos
then booking an 8-day small cruise ship
is the way to go. Not too practicable for a cruiser.
Make sure that your bottom is entirely clean before you arrive.
