What can we do in Suriname?

Hellooo everyone, currently I am in Suriname with my Suriname girlfriend. We will be staying for around 2 more weeks. Are there any things we could do on a budget? We will be around meerzorg this week and next week We will be going to Frederiksdorp. Also we have been around Paramaribo a lot and we have seen a lot of the historical sites. Right now we are celebrating dag der marrons. Ps we both dont have a driver license and need a taxi to get places.

All suggestions are welcome
