The Temple of the Goddess Kali at Pattaya

Hindu, not Buddhist, and that's the whole point of coming. Pattaya's religious life leans overwhelmingly towards the wat, so a shrine dedicated to Kali sits slightly apart from everything around it. It's small. You won't need an hour. What you get instead is the sight of an active place of devotion, offerings being made, the fierce iconography that goes with the goddess, and people there to pray rather than to photograph.

I'd treat it as a short stop rather than a day's outing, ideally slotted in alongside something else in the area. Go in the morning or early evening and it tends to feel calmer. Come with the understanding that this is a functioning shrine and behave accordingly, which mostly means keeping quiet, asking before you point a camera at anyone, and covering shoulders and knees. If Hindu practice in Thailand interests you, it's a genuinely worthwhile half hour. If it doesn't, skip it.
