My husband and I went on the parasailing adventure. You actually parasailing out in the bay area. It's a short boat trip, less than 5 minutes, out to the sailing area. The winds were not high enough for us to sail together, so we had to go separately - but that is up to the weather, not the operators.
Good instruction for those that had never been before. Friendly staff/operators. You fly in the air for about 7-10 minutes. It's very peaceful up there.
