My boyfriend and I booked the South Shore Explorer kayak/snorkel package two weeks ago (Aug. 9, 2013) and it was pretty awesome. It was my first time snorkeling--ever--while this was my boyfriend's second or third time. He actually went to Maui in 2011 and did the Pali Sea Cliff tour with South Pacific Kayaks, which is why we decided to go with them this time. Anyhow, despite my newbie-ness, everything came pretty easy and our super cool tour guide Garrett instructed us pretty well (for the record, I DO have kayak experience so for me that part wasn't very difficult anyway).
As for the tour guide: Garrett was funny and seemed to really know what he was talking about--whether it was about the island, the fish, some Hawaiian history or about the million dollar real estate you'll be seeing off the coastline. Fortunately, our group, which consisted of two other couples, were pretty friendly & talkative, too. I feel that your group could also affect your experience. Try coming out of your shell and bonding during the short tour!
The tour itself: Luckily, the waters were pretty clear even though we arrived not long after Flossie. The online description of a hearty paddle is no joke; while it isn't extremely hard, I did get tired after paddling a few miles + the first snorkel spot. We started at Makena Landing and I believe we paddled towards Kihei. While we did see a lot of sea turtles (pretty cool!), we didn't get to see many fish. Plus, the waters were not as crystal clear as I expected. Clear, but nothing like the magazine shots. At the beginning, Garrett did say he wasn't sure if he'd take us towards Kihei or more south--so afterwards, we wondered if south would have been better.
Nonetheless, the tour was great for a first timer like me. We stayed out there for about 3 hours, with 2 or 3 snorkel locations. Garrett brought his coolerbag & provided some snackbars & refreshments (super chilled water or juices) while we were out in the open water. Afterwards, we all sat and talked s'more while eating the provided deli sandwiches & chips. Nothing fancy for lunch, but the quaintness felt more sincere. He had a huge basket full of chips/cookes and he let us take a bunch of extras for the road + the extra drinks = bonus!
We are planning to go back to Maui for a wedding next May and quite possibly will book with them again (Pali sea cliff for me!), uh so, yes I do recommend!
