Here at Jetty Merang, you'll found several wooden shops selling swim wear, hats of various colours, pareo, slippers and souvenirs like key chain, fridge magnet, t-shirts and etc.
If you're looking for souvenirs with Lang Tengah written on it...that can be a bit difficult since most of the souvenirs made for Redang Island...hahahahaha. Anyway, I did found one stall selling fridge magnet with Lang Tengah written on it...it's the shop next to the jetty going to Lang Sari Resort. It was RM4 per pc...ok I guess...just as a remembrance.
You'll found restaurant too...simple local restaurant, but from my observation they're quite clean...so that's good enough for me.
All those shops will be selling this big island looking hat...for the ladies I believe...I bought 1 for RM10 since I forgot to bring my own. Before buying make sure you at least browse through other shops too...and don't forget to bargain. I found a shop selling a pareo for only RM13...and then found another shop selling the same quality pare for RM28...huh...lucky me I walked around...but I didn't buy any...was just 'price checking'.
It's the only shop on the island...well, that's according to the people here. After checking out all resorts...yeah...that's definitely the only one. It's a simple wooden shop located right inside Redang Lang Resort. From the beach, walk into the resort's compound...wash your feet first ...sandle/slippers are not allowed in the shop.
You can get plenty of stuff here like drinks, junk food, biscuits, bread, souvenirs, island wear, ice-cream, chocolates, sunblock and etc. Prices are of course slightly higher than in the main-land, but when we don't have a choice...what else to say?
