What a phenomenal experience! We did this for my 45th birthday and it was beyond amazing. I had a blast!!
It is not for the faint of heart, but the guides and the "herders", as they call themselves, are fantastic. They go above and beyond to make sure you're not only having a good time, but that you're safe
It's about a 65-70 mile round trip ride on a jet ski. They break us pretty often for water or if you need snacks or even if you just want to jump into the open ocean to swim.
Upon arrival to Catalina, they take you to these caverns, I believe called the Blue Caverns, where you can hop off your jet ski and swim through the cave. You can opt to swim with or without your life vest, but be mindful, you're still in open ocean waters so it's rough. I kept my vest on and it was a trip to swim through the dark cave. I loved it!
Once you're on Two Harbors, you've got about 3 hours to do whatever you want. We rented some lounge chairs from the Catalina Island company and hung out and had some drinks. It was perfect.
Heading back to Long Beach, the seas were rough, but the guides took really good care of us and we all made it back in one piece.
We didn't get to see dolphins on our trip out, but it's ok. It's not predictable and it's not their fault! Such a great time and a bucket list experience of a lifetime.
