Let's face it: You came to Tegernsee to see the Tegernsee, right? What better way to see the lake than board a lake boat? For a round-trip tour, you have two choices: A "large round trip" on Line A or B (a large boat, food and drink available, bicycles allowed aboard, a 90-minute trip, cost EUR 13), or a shorter "southern round trip" on Line C or D (a smaller boat, no food, drink, or bikes, a 70-minute trip, cost EUR 9). Note that the EUR 13 ticket is valid all day, so the long trip is probably your best value if you plan to take more than one boat ride. Point-to-point tickets and family tickets are also available. 10% discount with a valid Bayern-Ticket.
A fine excuse to fritter and waste the hours in an offhand way is to stroll along the lake shore. You can gaze out at the lake and watch the boats go by, or look inland and enjoy the decorated buildings. There are plenty of restaurants, shops and cafes available should your wallet feel too heavy. On the other hand, the numerous park benches are free.
the hike to wallberg is a very scenic hike that is just long enough to make you sweat.
the views from wallberg are very good and there is a cable car that you can take down if you don´t feel like walking back.
wallberg is also a ski resort in the winter, but i have only been there in summer months where it´s an ideal hiking spot.
You can take a cable-car from the Tegernsee valley to the summit, the Wallberg mountain, which offers spectacular views. On top, you can make a short hike around (you can climb up to a small shrine) and it's possible to hike back down to the base station (+/- 1,5 hours).
A fine and scenic hike from Tegernsee is the path to the chapel of Riederstein. The beginning part of the trail winds its way along the ridge for spectacular views of the lake and town as you ascend. The trail isn't too difficult (and arguably even stroller-friendly) until the guesthouse Galaun, just below the chapel. From there, it is a short but very steep scramble up to the chapel. On a clear day, the views are absolutely delightful. From the chapel, you can either retrace your steps, take a bike trail around the back side of the mountain and back to Tegernsee, or continue on to the more difficult hiking destination of Baumgartenshneid. I took the latter option with Richie and D; they had little problem, though I found myself huffing and puffing a bit by the end.
It is located about 60 km south of Munich and about 30 km from the Austria border, surrounded by pre-Alpine beauty.
The towns on Tegernsee are typically Bavarian and very beautiful. Many wealthy people live on this lake.
