Martins Bay Holiday Park is a beachfront camping and holiday park at 287 Martins Bay Road, Mahurangi East, in the Rodney district about an hour north of Auckland. It faces Kawau Island across the Mahurangi Peninsula, and it offers camping and caravan sites along with a range of accommodation. Facilities include a camp shop at reception, a shared recreation room with a large flatscreen TV, a foosball table and a reading area, and a covered outdoor area with electric barbecues and picnic tables. Watercraft and pedal cart hire, wifi passes and late check-outs can be arranged at reception, and laundry and shower coins are sold there. Boat storage is available short and long term, with casual storage booked in advance. Gates open from 6.30am to 10pm, with the camp shop open during the same hours.
The park is also a base for fishing and boating. An all-tide boat ramp sits beside the park, and it is provided by Auckland Regional Parks between Labour Weekend and Easter. The park has a fish cleaning area with a filleting table, and three bays with coin-operated taps for washing boats. Fishing and gathering off the rocks or beach are not permitted here, and motors should not run after 7.30pm. The park says its facilities can be very busy at weekends when there is a competition on. For a family wanting beachfront camping near Warkworth, or a boat owner heading out to the Hauraki Gulf, the park combines both.
