Access to Western Compounds when not a resident

Hello,
don't worry. There are lots of pools and gyms in Riyadh. Near DQ there are for example Olympic Pool Riyadh, Swimming Pool USERA. The are also spas, wellness and gyms right inside DQ. I don't know about the prices. I, myself stay in compound where I can use the gym and the pools for free.

I wish you find the appropriate facility.
Good luck.

Hello Todd,

Glad to know that you will be moving to Riyadh soon, I will be moving to Riyadh in February and looking for a nice place to stay with my mother, can you please share the details if it's okay of the place you're staying,

Thank you
Ankit

For expat compounds, you need to be invited by a resident.  There is usually no membership that allows outsiders to access the facilities.   But there are many facilities in or near DQ as mentioned by the previous poster.
