You may need a visa for Uganda if you have a Trinidad and Tobago passport

This visa is for travellers visiting Uganda, Rwanda, and Kenya for business or tourism during one trip. Travellers can travel freely between these three countries, entering and exiting each country multiple times. Travellers must start their trip in Uganda. The visa becomes invalid if travelling outside of these countries. An eVisa is the fastest and easiest way of obtaining a visa as you can submit an application and supporting documents online. If approved, travellers receive their eVisa confirmation electronically. When travellers arrive at immigration they will be asked for their passport and eVisa to ensure they have proper documentation.

You don't need a visa. You can travel to your destination for a limited stay. Be sure to check other entry requirements and how long you can stay for.
