There are several ways to browse Gopher sites on your computer:

The slickest and easiest solution is to install Lagrange. It's fast, the interface is clean, and it's available for iOS and a multitude of other platforms. Even better, it also supports the Gemini protocol, which is sort of a modern version of Gopher with a few extra convenience & markup features.

If you want more options, check Wikipedia, but I'm telling you that Lagrange is the way to go.

If you are using terminal you have a few solid options here. First are the text-mode web browsers Lynx & ELinks, which have decent built-in Gopher protocol support. For dedicated clients, ncgopher & Bombadillo are highly revered by the Gopher community. And yes curl supports it as well, if you need to start scripting Gopher requests.
