What do you do for fun in Pretoria?

(Pretoria East, Gauteng, South Africa)

Hi Mbini! We recently moved to Pretoria from Cape Town. We are bored out of our minds over weekends! No beaches, no mountains, no wine route.
What can you recommend for us to do over weekends? We've been to the zoo, most nature reserves, parks, monuments, hartebees....What is there to do here? Everything is so far and expensive.
In Cape Town, in a 60km radius, you have 20 different beaches, 2 mountain ranges, waterfalls, the wine route, rivers, parks, dams.... What does Pretoria have to offer that is fun?
We love being in nature.
