Answer
Many sanctuaries have specific policies regarding outside food, so it's a good idea to check their website or call ahead.
• Some places might have picnic areas where you're welcome to enjoy your lunch, while others may have on-site cafes or food stalls offering meals and snacks.
• If outside food is allowed, make sure to pack items that are easy to eat and won't spoil quickly, as well as any necessary utensils.
Practical Chiang Mai planning note: Confirm current routes, fares, operating hours and pick-up arrangements before travelling. Build in extra time for traffic, weather and festival road closures, and keep the destination name or map pin available in Thai for drivers when practical. Confirm that any named venue still operates and check its present opening days, booking method and location directly.
