Summit Lake Provincial Park is located between Slocan Lake and Upper Arrow Lake which is 18 kilometres (11 mi) southeast of Nakusp.
The Nakusp Range of the Selkirk Mountains rise 500 metres (1,650 ft) above the lake, providing a magnificent backdrop on which mountain goats can often be viewed on the rocky outcroppings.
Park visitors can enjoy fishing for rainbow trout or swimming in the lake’s clear, refreshing mountain water. A natural spectacle occurs at the end of each fall as thousands of Western toads, emerge from the lake foraging for food on their migration to the forest, their winter habitat. Please do not disturb their habitat and observe them from a distance.
The small park and campground is located on a point of land at the south-west end of Summit Lake. The campground is circular, with a gravel, one way traffic road and contains 35 vehicle accessible sites. Seven of the sites are doubles. There are no pull through sites, tent pads or tent sites. The sites are shady and small, in an intimate setting along the lake front or with in the cedar hemlock forest. Extra vehicles can be parked in the day-use parking lot located near the park entrance. A pay phone is nearby at the pump house found in the centre of the campground.
This park offers vehicle accessible campsites on a first-come, first-served basis – campsite reservations are not accepted. Visitors can select any site and staff will come to collect fees.
The day-use/picnic parking lot is a short walk to the lake. Here you will find a 100 metres long, shale/pebble type beach. At the edge of the forest, approximately 10 metres from the shoreline, on a small grassy area are 6 tables. A pit toilet and water tap is nearby. There are no fire pits or barbeque stands. In the campground by campsite #1 is a grassy field with an open picnic shelter containing a wood stove. Campers and picnickers use both.
The Park is open year-round unless inaccessible due to weather conditions and the campground is open from May to September.
