The National Wetland Trust is developing a National Wetland Discovery Centre at Lake Serpentine/Lake Rotopiko next to Ohaupo Road/SH3 between Ohaupo and Te Awamutu. An area of about 9.5 hectares, including Lake Rotopiko and a wetland forest area, is enclosed in predator-proof fence. There is a well-formed track encircling Lake Rotopiko with some activities for children along the way, and a track through the kahikatea forest adjacent to the lake. The Department of Conservation is also involved, together with the Toyota Kiwi Guardians organisation.

A parking area for visitors to Lake Rotopiko is accessible directly off Ohaupo Rd/SH3, but due to a wire rope median barrier the access is only for vehicles travelling south from Ohaupo. The entry, through a gate which is closed at night, is unmarked and is located between McFall Rd and Jary Rd. There is a turning bay on Jary Rd for those heading north after a visit to Lake Rotopiko, as only a left turn is possible when leaving the carpark.
