Surin Beach is small enough to explore on foot — the bay is roughly 600 metres from end to end, and all the beachside restaurants and facilities are reachable by a short walk along the sand or the beach road. The headlands at either end of the bay are accessible on foot as well, though the paths are rough.
Scooter: The most useful tool for getting around the wider area. The coastal road connecting Surin with Kamala to the south and Bang Tao to the north is easy to navigate. Scooter rental is available locally, or bring one from elsewhere on the island.
Songthaew and taxi: Local songthaews serve the main road but don't run a frequent scheduled service. Grab works in this area and is the most transparent way to book a metered ride for a trip of any distance. Tuk-tuks are around but price-gouging is common — agree on the fare before getting in.
On foot: The beach road itself is walkable, and there is a footpath along the shore between Surin and the Amanpuri end of the bay. Walking any distance off the beach in the midday heat is not recommended — the sun is intense and there is limited shade on most roads.
