Grindelwald is one of Switzerland's main and most popular alpine villages along with Lauterbrunnen…read more The Eiger mountain towers over the village and it's known for being the way to get to Jungfraujoch, known as the "top of Europe". From Interlaken Ost it's a 35 minute train ride.
Note that there are two main stations in Grindelwald: Grindelwald Terminal which is the way to get to Jungfraujoch, and Grindelwald (nothing else in the name) which is the village. Grindelwald Terminal is the second to last stop and Grindelwald is the last stop, but some trains only stop at the former.
Some popular attractions other than exploring the village are Pfingstegg, a toboggan ride that you can take for a unique view of the village. Another one is visiting First, advertised as the "top of adventure" and where you can go zip lining, mountain carting, and hiking among other things.
Of all the places I visited in the region, Grindelwald was my favorite place to see because of the vast greenery and landscapes. It's just exactly what I imagined Switzerland to be before I visited and it lived up to that expectation.
