I like to have a bit of a workout in those public gyms you find in parks in cities and towns around the world.
I especially like to find ones with chin-up bars, especially if one is high enough for a tallish westerner to use.
I found one in Saigon and I found one in the very first border town after I walked across from Cambodia to Vietnam.
But it's my eleventh day here in Dalat and I haven't found one despite lots of exploring. But, Dalat is a mountain town with all curvy windy streets so it's very easy to miss entire sections.
I also don't mind walking a few kilometres out from the centre.
