State Park Campground Guide

← Previous state | Next state →

The state of Maine brings to mind iconic images of lighthouses, lobster rolls, and rugged, rocky, forested coastline. Visitors gravitate to popular destinations like Acadia National Park and the vibrant capital city of Portland. Yet this is only a small portion of the state, which comprises nearly half the total area of New England. Inland Maine boasts an abundance of forests, pristine lakes, rivers, and mountains where hiking, kayaking, canoeing, fishing, wildlife viewing, and winter sports are all popular activities. Maine’s cities, universities, and charming small towns dot the wilderness throughout the state. There are plenty of opportunities to experience the great outdoors while staying close to creature comforts.

With more than 30 parks, 11 of which can accommodate RV camping, the state park system provides a gateway to the lesser-known landscapes and highlights of the state, as well as the must-see Atlantic Coast and attractions of Downeast Maine. Campgrounds are rustic but well maintained, with a focus on the natural surroundings and outdoor recreation. Some sites can fit RVs around 40 feet, but there are more options available for smaller rigs. Given the harsh winter weather, almost all campgrounds are seasonal only. Maine state park campgrounds are an economical way to experience the best of this rugged New England state.

Featured Campgrounds

Lamoine State Park

23 State Park Road, Lamoine, ME 04605

This oceanfront state park is located in the heart of Downeast Maine, one of the most popular destinations in the state. Lamoine’s peaceful setting with easy access to Acadia National Park and Bar Harbor is an ideal base to tour the area’s iconic rocky shoreline, islands, and lighthouses. Boating, fishing, and trail walking are popular activities, but the park’s main draw is its beautiful views of Frenchman’s Bay.

The campground offers just under 50 sites for RVs. Many can accommodate RVs up to 30 feet, with a limited number for larger rigs. There are no hookups, but facilities include potable water, an easy-access dump station, and well-maintained bathrooms and showers. A ranger station, playground, and loop trail are also available to campers.

Lily Bay State Park

13 Myrle’s Way, Greenville, ME 04441

In a state with an abundance of breathtaking landscapes, Lily Bay State Park stands out. Located practically in the middle of the state, away from the more popular Atlantic coastline, this lesser-known park rewards visitors with spectacular water, forest, and mountain views. Visitors can traverse the miles of forested shoreline and coves on sprawling Moosehead Lake by foot, bike, kayak, or canoe. Wildlife viewing is a highlight, since moose are a common sight in the park. An easy hike up Mount Kineo offers panoramic vistas from a repurposed fire-watch tower. Nearby, you can also tour the stunning Gulf Hagas area’s gorges and waterfalls.

Lily Bay’s campground has over 50 RV sites tucked among the trees. A few sites can fit RVs up to 35 feet, but the majority are for RVs under 30 feet. The campground has no hookups. Facilities include restrooms, potable water, a central bathhouse with separate shower rooms and a dishwashing sink, a dump station, and a playground. The town of Greenville is a few minutes’ drive away for shopping. If you have time to travel away from the coast, you won’t be disappointed to include Lily Bay State Park in your itinerary.

Sebago Lake State Park

11 Park Access Road, Casco, ME 04015

This popular Maine vacation spot was one of the five original state parks in the country. Opened in 1938, Sebago Lake State Park’s 1,400 acres at the base of the White Mountains encompass expansive woodlands, sandy beaches, ponds, bogs, and rivers. This diverse landscape creates habitats for a variety of plants and wildlife, and outdoor activities like swimming, hiking, fishing, and boating. Sebago is the deepest and second-largest lake in Maine.

More than 200 campsites are available, some with electric and water hookups. Many sites can accommodate RVs between 30 and 40 feet. Facilities include restrooms, showers, potable water, a dump station, and a playground. The park offers boat rentals, outdoor movies, and a wide variety of ranger programs throughout the summer for kids of all ages. The park can get crowded with day-trippers in the summer, but it’s a fun family destination beloved by many year after year. Campsites are in high demand and get fully booked as soon as the reservation season opens. Note that for camping between May 24 and September 12, a minimum of four nights applies if you book your reservation during the month of February.
