BB Tours provided us with an excellent day of snorkeling! The guides were friendly and extremely helpful, even lending us a much needed prescription snorkel mask, as I have very little experience snorkeling and had completely forgotten that sight for my partner who only owns glasses (no contacts) would be a huge issue! They provided drinks and snacks for the journey as well as a delicious cooked meal of Thai food, including vegetarian options. We went to 3 reef spots and saw an exciting variety of fish and coral. One of the guides very enthusiastically informed us about the type of reef life we might see and at the last spot he found an adorable sea slug (jorunna funebris) and showed it to me and let me hold it! I will warn you to be careful of the rocks that have many sharp shells/barnacles. Be very mindful of your exposed limbs. I cut my knee pretty badly at the last stop -- one of the guides cleaned it with some alcohol and dressed it with iodine and a good fibery bandage.
