Eco Guide Cafe has run its ECO-manners reef tours since 2008, and the company won a special prize at the Ministry of the Environment's Ecotourism Awards in 2010. The Blue Cave and Bijyas trip suits people who get seasick, because the big 50-seat boat is only minutes from the reef with a toilet and changing room on board. The shop's English and Chinese pages make booking easy from abroad.
Snorkel-only guests can fly out the same day, and the shop puts Shimojishima Airport about 20 minutes away and Miyako Airport 30. The terminal at Sarahama has no showers, so arrive in your swimsuit. In the cooler months, rent the wetsuit.
