Located in an isolated part of the island it is best suited for those seeking a quiet time. One 3km paved road leads to Teluk Dalam beach. They do offer a boat service to Long beach. General boat services are very expensive.
I found all the staff friendly and helpful.
I made a prepaid booking two months in advance and was allocated one of their best sea view rooms as a result. The resort overall is still in pretty good shape given its age.
My room was modern looking and decent size. Fitted out with a wardrobe, desks and chairs. The aircon, fridge and TV (with english movie channels) all worked just fine. The lighting was adequate but poor over the work desk.
The bed had clean linens and afforded me a comfortable sleep.
The bathroom had a segregated shower with hot water and decent watet pressure. As you would expect, toiletries were provided.
The balcony had a table and two chairs. Nice to sit and relax particularly when there was a slight sea breeze.
The food at the restaurant was okay albeit pricey. I found it amusing that at the free buffet breakfast the Malaysian guests would pile in but come dinner time no where to be seen.
Overall, even though this resort was not my first choice, I think it was a blessing in disguise as Long beach was packed with tourists.

Dont bother staying at Redang Island Resort.
1) Overpriced. RM510 per night for a room that is old. Not worth it.
2) Far from beach/ restaurants. The nearest beach is a 1 hour walk. And they dont provide complimentary transport service to the beach. Poor.
3) Nosiy. Everytime the person staying upstairs walks, you hear it. And the connecting door to the adjacent room cannot be locked. And one night the person next door accidentally opened the door to our room. WTF.
4) Staffs. Giving contrasting info. Not helpful.
In conclusion, dont stay here. Even the dive instructor that we talked to said there are other better options out there.
Hope this is helpful for you guys. Cheers.

Redang Island resort was one of the first resorts in Redang and has a great view on the hill overlooking the main harbour / port. Whilst not directly on the beach it does offer morning snorkel trips (10am to 1) and an evening transfer to long beach for dinner options (6-10pm), both of which should be taken up since the highlight of Redang is its snorkelling and beach vibe.

Dinner at RIR was not great with an uncooked fish and chips (also missing the lemon noted in the menu as there was none in stock) whilst the beef burger was not great. Maintainace is clearly an ongoing issue with the room having problems with its shower & hot water whilst the pool was not fit for swimming (irrespective of the snake we saw both mornings by the loungers!).

On the more positive side the transfers were well managed whilst the staff were keen to help albeit constrained by what they could actually do

Rooms on the sea side are significantly better than the forest side given views and light.

Rating is a generous average (3stars) but it deserves better than poor (2stars)
