Things to do nearby
Long a wellness and yoga retreat island beyond the Full Moon Party crowd, Koh Phangan draws nomads for cheap beachfront coworking spaces, jungle waterfalls, and a slower pace than Bangkok.
Srithanu — yoga/wellness hub, coworking cafes, center of the nomad scene
Thong Sala — practical base, main pier, markets and banks, less curated
Haad Rin — Full Moon Party area, isolated from nomad hubs, avoid for long stays
Getting around
A scooter is essential since taxis are pricey and infrequent; ferries from Koh Samui or the mainland (Surat Thani/Donsak) run 30 minutes to a few hours, and Samui airport is the nearest gateway.
