We have been on this semi-submersable sub 2 times in the last 6 months, and my kids love it. My 1 old yells at the top of his lungs- FISH as we move through the water. And my 3 and 5 year old thought the fish and the food torpedoes were awesome. If you get sea sick, take your dramamine... More

Part of a package, and leaves right from the pier. Staff was knowledgeable about different fish, and were able to feed them, with debit card available, of course.

The guide and underwater experience was hands down worth it, and I am not a water person at all. I live on the beach and rarely go in beyond my ankles. The promise of photos "the next day", however was way off. It took a while to get the photos even after emailing them a few days after our tour.... More

I am not a fan of underwater activities - specifically snorkeling. Get panicky worrying about water getting in the mask, sucking in water, not being able to see (I wear glasses). However, the Trek was perfect. The helmet enabled me to wear my glasses and breathing was a breeze. Basically, the helmet is an updated diving helmet. Guide was fabulous.... More

The whole family of 7 had an amazing time! The experience itself was spectacular...walking on the ocean floor, 30 feet underwater amidst a kelp forest, local sea bass, garibaldi and tons of baitfish. Seeing the look of utter glee on my 7 year olds face was the best part while he jumped up and down semi weightless like walking on... More
