Activities in Engelberg region
You can find information on activities at Engelberg in summer from the Engelberg Tourist office page :
The lift system of Engelberg operates throughout the year, including the summer season.
There are several hiking and mountain biking possibilities. There are geology trails for families and more testing hiking routes for more experienced walkers; while there are around 14 cycling trails to choose from and you could even rent an electric bike to check out the scenery without the stress. The Lake Lucerne region is great in the summer too with mountain views, countryside excursions and lakeside fun to enjoy.
Anyone who loves to climb will be positively spoilt for choice in Engelberg because there are a host of climbing sites and trails to push your limits. It’s also a great location for Via Ferrata with some areas helping children to get started and others offering spectacular climbs with real variety and action. It will take a really wild visitor to test themselves with a spot of bungee jumping or to take a ride on the notorious devil bikes. However, the summer Toboggan run is ideal for all the family, as you enjoy summer bobsledding at Ristis. For something more relaxing why not watch your children’s eyes light up with a spot of pony riding; head to the 18 hole golf course for a round; or see if you can catch your own supper with fishing at Lake Eugensee.

Here is Engelberg info from Wikipedia:
Engelbergis a resort town and municipality in the canton of Obwalden in Switzerland. Besides the town of Engelberg, the municipality also includes the settlements of Grafenort, Obermatt and Schwand.
Engelberg is the leading mountain resort (Urner Alps) in central Switzerland. In the Middle Ages, Engelberg was known for the educational accomplishments of its Benedictine monastery, the Engelberg Abbey, whose school was well-known and regarded throughout the country. From the 19th Century, Engelberg became internationally known as a resort and spa, but is today visited as much for skiing as for its clean air. With its combination of modern sports facilities and alpine location, Engelberg is a magnet for both summer and winter tourism. The closest large cities are Lucerne and Zurich.
The municipality of Engelberg is served by two stations on the Luzern–Stans–Engelberg line. Engelberg station is located within the resort of Engelberg and is the terminus of the line. Grafenort station lies to the north, one station down the line. Both stations are served by hourly InterRegio trains from the city of Lucerne.
The average temperature in Engelberg is 20.7 °C (69.3 °F) in July.
