07/09/2012 Lisa Davis (Avg: 3.25 Review) - July 8- Dove Treasure Island but stayed in the sandy areas to practice navigation. Not very experienced yet so we thought it best to avoid the reef with the conditions. Parked in the upper lot, get there early to get a spot or you are out of luck! $4 for 3 hours of parking but there are nice public restrooms at least. Lifeguard was present. Entry was easy, drops off fast so we were in chest deep water fairly quickly. Vis was at 10-15 feet at best, pockets of 5 feet occasionally. Went to depth of 30'. Current was moderate. Watched a sea star walking on the ocean floor, saw a few fish, and watched an epic battle between a hermit crab and a crab. Exit wasn't bad. Will return again soon!

07/03/2008 Brian Xavier (Avg: 3.20 Review) - Dove the right side of Aliso which is called Treasure Island. Parked in the upper lot. Took gear to the far right beach and entry was great. Vis wasn't too good, but I think this could be a great dive. Quarter machines for pay parking. Dove to 30 feet.

10/10/2006 Victor (Avg: 4.19 Review) - I lived in Treasure Island for a couple of months and enjoyed this spot tremendously. Unfortunately, the construction that killed the trailer park killed the sea life as well. The entry is on the N end of the beach and it is usually protected from the surf, you will get a workout moving your gear though, so rest before you go in. You swim to the W and it gets deeper but never more than 30-45 ft with a beautiful scenery of coves and sandy bottom, it used to be covered with algae and sea urchins, now it's minimal. There were plenty of holes with lobster and Garibaldis being king here, few calicos and a few rays and halibuts. If you progress towards Aliso Rock keep an eye on your position as the conditions radically change around the rock. Surf, swell and currents along with very sharp rocks don't make a pretty picture, but if you dare that far you will see some perch and mussels, lots of foam and more life. The runoff did not get there that much. This site is frequently visited by local agencies, including police and lifeguards, so if you fish have your license handy. Once you get back to the picnic area you'll see restrooms, showers and snack spot. Parking gets difficult during summer time and many people just park along PCH. I recommend Javier's (Mexican restaurant) for after your dive!

05/16/2004 Derek Broe (Avg: 4.05 Review) - Treasure Island just north of Aliso beach is a great dive. There is a new parking lot at the montage resort. Easy walk to beach on a new path developed for the resort. Winter is the best to dive. During lobster season the place is full every night. Usually calm conditions. Great reef and sea-life to be seen.

03/10/2004 Anonymous (Avg: 3.43 Review) - The best area is at the very north end of the beach where the reef and Aloso rock starts. Great underwater structures and caves as you progress North through the reefs. At the very tip of the rock formation the current and swell are very strong DO NOT GET CLOSE TO THE REEFS, you can get projected to it and risk injury or death ( Summer 1994) Life and plants are there and not near as abundant as it used to be before the construction started on top of the cliff. The storm water runoff deposited so much dirt and soil than the area lost 50 to 70% of its beauty, it is however still very interesting and inhabited. Night diving is great, lots of lobsters, calicos, perchs, Garibaldis and some occasional sand shark and rays still swimming around. Be safe.

You will find some swells here, but you won't be pounded on any rocks! Take your buddy's hand and practice your entry and exit skills. Enjoy the reefs just a short swim from shore.
