ABOUT THE LOCATION
Bua Had Park is Chiang Mai's only public park. Of course, there are other recreation areas, but none are in the city limits or accessible by public transportation. Bua Had Park is a great place to hang out. Rent a mat, read a book, feed the fish, get pooped on by pigeons. You can do it all here.
If the weather gets too hot then head to the air-conditioned coffee shop for a coffee or smoothie and enjoy the beautiful view from the comfort of the cool air.
The cache requires you to be extremely stealthy and careful so as to avoid detection, as the park can be pretty crowded - even in the mioddle of the week. And more so on weekends!
