Located on the southern end of Lake Washington, Renton enjoys a fantastic setting amidst water, mountains, and forests. Start by visiting one of the city's over 30 public parks. The most popular one is Gene Coulon Memorial Park. It has paved walkways, a bird sanctuary, a children's play area, and a tennis court. It's also a great location for swimming, boating, and sport fishing in the warmer months.
If you want to get more into nature, make the drive to Cougar Mountain near Issaquah. This regional park is a favorite among locals looking for an easy outdoor adventure just outside of the city. Hike the near 40mi of trails, which feature forested slopes, waterfalls, and great panoramic views.
For a relaxing experience of floral beauty, the Kubota Garden is just over the city line in South Seattle. Begun in 1927 by a Japanese immigrant, it's now run as a city park. It's a showcase of Japanese-style gardening, with several themed areas, a pond, creek, and a bamboo grove. The garden is open during daylight hours every day of the year.
