This is a tough climb. It gains 2200 in 5 miles of which 1.1 miles are flat or downhills! There are 3-4 short segments with 15% gradient. The road is exposed so riding when temperature is below 75 is recommended. On summer weekends expect caravans of motorcycles with their fumes and noise. It is a super special experience. Be patient on climb and cautious on the descent. There are restroom facilities but no potable water. This climb is addictive! You will be back! There are locals who climb this road 100+ times annually!

This is not a very exciting trail to hike. Itβs pretty much a trail surrounded by thick walls of vegetation, with almost no opportunity to view your surroundings. The trail is 70% rocks/gravel, and 30% hard packed clay, so avoid wearing snickers

If you make the summit a fantastic view awaits. Be aware the road goes down then up to the road about then up again to the summit!β¦

A small but cozy beach along East Cliff Drive, featuring a lake and a park. Thereβs bike parking nearby and benches overlooking the water, making it a great spot to pause during your ride, enjoy the ocean views, or even take a refreshing dip. The beach is especially nice during low tide.

Climbing Mount Umunhum is a tough but rewarding challenge. The road is steep, with sections reaching up to 18% grades, so pace yourself. The views from the top are spectacular, making the hard work worth it. Start early to avoid traffic and the heat, and be prepared for a long, demanding ascent.

An excellent spot to take a break and enjoy the full breath of Lexington Reservoir. There is a Plaque dedicated to deputy Douglas B. Miller, who was fatally wounded while performing his duties.

The Mount Umunhum Trailhead offers some amenities, including bathrooms at both the start and summit. With parking available for about 20 cars, this trail provides great views and is a great spot for sunsets. Aim to hike early in the morning or in the evening as it can get very hot in the summer.
