Chiang mai night market. The place you can find everything.

Go to a silk factory and have suit made in 24 hours. It'll cost you about 160 Euro and they do a fantastic job!

Beautiful warm friendly people. Visit the night market. Enjoy bartering. If your store keeper stops smiling you have pushed him too far. Keep it fun.

Don't worry about dragging around trekking gear your whole trip just for a popular hilltribe trek...there are great trekking gear rental stores in Chiang Mai that are cheap! You can rent a sleeping bag, backpack, sleep mat, and can stock up on things like bug spray and rehydration salts. Just keep the rentals clean and in condition and you will get a deposit back upon returning the items.
