It's worth noting that La Gomera is quite far from the more western islands: Gran Canaria, Fuerteventura and Lanzarote. Visitors staying on those islands might need to plan their La Gomera visit ahead of traveling to the canaries.
flew to Tenerife in 2019 and took a ferry to La Gomera, wasn't big deal to do so. Then just rent a car and travel around the island by yourself. Fortunately, I was able to experience the language myself when I hiked to Mirador de Abrante. The old dock for banana ships (or at least what's left of it) is also well worth seeing (Pescante de Hermigua). I could talk for hours about my stay there, an incredibly beautiful place.
