Lake Okaro, situated near SH5 and SH38 between Rotorua and Taupo, is the smallest of the Rotorua lakes under public management. The lake has had poor water quality due to runoff from surrounding farms, but efforts have been made in recent years to improve the water quality, so that it can now be used for recreational use. The lake is adjacent to Okaro Road, off SH38 near the intersection with SH5. There is a campground, a boat ramp, and public toilets by the lake and Okaro Road. Te Ara Ahi, the thermal cycleway, passes by the lake on Okaro Road.
There is a walkway of about 2.3 kilometres around the lake, with a nominal time of 1 hour. The walkway follows the lake edge, with only relatively easy gradients on some smaller climbs. Vertical height difference is only about 20 metres for the track. About one quarter of the track, on the north-western border, is wheelchair accessible according to the signage. There is a charge for overnight camping, payable at the Rotorua i-Site on Fenton Street.
