Cabs, bikes or the two-foot taxi. Cabs are mainly cash only. We recommend grabbing a card from the first cab you take so you have a phone number to call next time you need a ride! You can rent bikes from one of the many companies spread out across the island to get around as well. Most places on the island are walking distance.
Block island is cash-heavy - cabs, bars, etc. Be sure to bring cash if you want to avoid ATM fees, but there are plenty of ATMs on the island as well.
Rentals on AirBnB or VRBO can be hard to come by. If you plan to get a house on Block - use these sites in addition to the usual apps: https://www.birealty.com/ https://bibeachrealestate.com/ https://phillipsonbi.com/ https://www.sullivanbi.com/ https://www.blockislandchamber.com/
Accommodations on the Island fill up quickly and we highly recommend you book early!
We recommend calling the hotel or Inn directly as they aren't the best at keeping websites up to date. Most accommodations on the island are Inns.
