Walk along the side of the lake, then double back, climbing steadily to the observatory. It's a steepish descent directly back to Tekapo. Brilliant views, quiet, well signposted.

Much cheaper than flight from Mount Cook airport and every bit as spectacular. Often bargain price if you book late afternoon for same day.

Try Google, or do it when you're there

It is right by Lake Tekapo and is a small campground right on the edge of the lake. There is an honesty box to pay your camp fees which are only $5 per person per night. There are toilets there too.

Turn right after Lake Tekapo and head in the direction of the observatory. Carry on after the observatory and turn left. Signposted as a dept of conservation area. Or ask at the visitor info before you leave the village.
