We traveled with Trips and Tramps from te anau and we cannot recommend them more highly. We had a fantastic guide in Geoff who was born in manapouri and knew the area extremely well. The trip along the road, thru the homer tunnel and to the sound was well organized and run. The boat trip went in close to the magnificent cliffs of the sound and was small enough that everyone on board got great views of the waterfalls, seals and flora. The waterfalls were impressive. A great day out.
