What Travellers Say
Reviews Summary
Diamond Cave offers a unique, albeit brief, natural experience with its resident bats and interesting formations. While the 200 Baht entrance fee is considered high by many, visitors report success in bargaining it down. The rough interior path and guano on handrails are minor drawbacks, but the eerie atmosphere and the chance to see bats make it a worthwhile stop for many.
"The cave itself was really cool. I absolutely love bats and to look around so we were about 15-20 minutes inside. The only remark I have is the price. I think 200 baht is way too much. If you don’t mind the price and really love caves, I’d say do it! If you’re just a tourist looking for something new, don’t do this cave. There are plenty of free caves on the Island."

"Really enjoyed this cave. Small but spectacular. Watch out for the handrails underneath the bats as they are covered in guano."
Ray Brunton
"Nice cave to see. Unless you are a cave lover you will spend max 10 minutes inside. Kids liked to see the bats attached to the ceiling. The path is a bit rough (so not for wheel chair or stroller) but not dangerous. Entrance 200 BTH (a bit exaggerated taking into consideration the local prices and length of the attraction that’s why 1 star less)"

There are no significant facilities directly at the cave entrance. Basic amenities might be found near the longtail boat drop-off points on Railay Beach.

Capture the eerie atmosphere of the cave interior, the unique rock formations, and the resident bats. The short walk to the cave also offers scenic photo opportunities.
Use a camera with good low-light performance or a tripod if possible. Avoid using flash, as it can disturb the bats. Focus on capturing their silhouettes against the cave walls.
For Different Travelers
Tailored advice for your travel style
👨👩👧 Families with Kids
Given the cave's small size, the visit will be brief, which is often perfect for keeping young children engaged. The unique environment and the chance to see wildlife can make it a memorable part of a Railay Beach day trip. Remember to try and bargain the entrance fee, which can make the experience more budget-friendly for families.
💰 Budget Travelers
Consider this cave as a short, unique add-on to your Railay Beach exploration rather than a primary destination.

Understanding the Entrance Fee
This negotiation tactic is a common practice in some tourist areas in Thailand, and it seems to apply here. While the cave itself is small and the exploration might only take 10-20 minutes for most, the unique experience of seeing the bats and the cave's natural formations can still be worthwhile, especially if you can secure a better price. For those who are passionate about caves or unique natural phenomena, the fee might be less of a concern.
Navigating the Cave's Interior
Despite these minor challenges, the cave itself is considered small but spectacular. The interior offers a unique atmosphere, often described as eerie and quiet. Visitors can expect to see interesting rock formations and, most notably, a colony of bats clinging to the ceiling. The experience is relatively brief, making it a quick but memorable stop for those exploring the Railay Peninsula.
