Charlie claws is technically a restaurant however they own their own boats, dhow, and snorkel and diving equipment.

Thus, they offer a day trip excursion to go and see the Dolphins and allow their clients to snorkel in the ocean.
I went for the package that included snorkelling, diving, lunch at the restaurant and also a tour around the village (total cost USD$160).
This is inclusive of equipment hire and all transport.

I must say this experience was fantastic. The staff were friendly, knowledgable and really put our group at ease.
The dhow is very bumpy on ocean waters so I recommend taking anti-motion sickness tablets (well in advance) to those who are sensitive to it.
I initially was only going to snorkel however took up the offer of scuba diving (to a maximum depth of 6m) for a $30 fee (usd). The snorkelling was fantastic with a wide range of colourful fish to see.
The diving however was beyond anything I've ever done and was simply amazing. We had an excellent teacher who showed us exactly what to do.

I recommend this day package to anyone and everyone visiting the Mombasa area. Charlie claws offered a fantastic day and we all enjoyed ourselves.

A wonderful experience. The staff were really friendly and the swimming in the indian ocean was incredible Highly recommend this for anyone as was travelling around the island. They also catered wonderfully for our vegan palate

Charlie Claws runs a day trip on a local dhow that includes snorkeling or scuba diving (for a modest additional fee) around the Kisite-Mpunguti Marine National Park then lunch at their facility on Wasini Island. After lunch you can walk around the island or relax at some saltwater lagoons until time to head back to reality. Because of security warnings issued by several countries many of these local attractions are suffering from lack of tourists. The crew of Charlie Claws were great, the dhow was fun and lunch tasty. I felt bad for the crew that business is suffering but they were all in good spirits and FUN to be with.
