We took a double kayak without a guide for an independent walk through the mangroves.
100 dirhams came out in two hours. As a deposit, they didn't leave anything except a phone number and mail.
The kayaks are in good condition, as are the paddles. The vests were good. Things were left at the guys on the pier in a box.
After a walk, there is a place to change clothes (mint tent / tent) and rinse your hands and face in a drawer.
I recommend taking a change of clothes and water with you.
