Christchurch harbour is tidal. At low tide the water depth reduces and the area available to paddle in is reduced. It is still possible to go out, but you need to stick to the channels and walk out over the sandy mud to the water. Our staff can direct you and help you take kit out. On the hire booking slots we have marked out when this is. If it says ‘low tide, restricted area’ on a time slot it means for part of that hour there is a significant restriction. So if booking two hours do look ahead at the following hour.
