We're heading off on a trip down to Milford Sound and Invercargill at the end of August (with a stop over at Kat's en route!! ). We'll be staying mostly in Top Ten campsites in their chalets cos they're cheap and well equipped and usually in great locations.

Has anyone done Milford Sound and if so, would you recommend the boat or plane trip? Are there other alternatives?

Plus, I know there's the glow-worm caves to visit - what else is there I should do, or avoid, down that way?

Cheers
