We did a 90min kayak tour of La Jolla Cove, and we were also able to enter one of the Sea Caves. The guides Sam and Dan were great, it was a beautiful day out and the water was 71 degrees, which made the tour even more enjoyable, We were in a two person kayak, and it was a very leisurely kayak out to the caves. Beginner kayakers would have not problem. You did get almost completely wet just getting past the waves, so we wore swimsuits. The whole tour took about 2 hours by the time we were completely done. It was great, I would highly recommend it. The only reason I didn't give it 5 stars is that our tour was canceled 3 times and then rescheduled once. The canceling was for unsafe conditions, so we understood, but the first time they canceled we drove there and parked, and then at the place they said they forgot to call us and say it was canceled. If you buy a travelzoo or groupon to use on a certain day, be prepared that you may not be able to use it that day. Overall very satisfied with the tour.
