Nice view of Lake Jennings! More difficult than rated with several gains in elevation. Lots of rocks, sandy washouts on trail. Hiking poles would have been helpful. Only saw one other human!

Moderate inclines and descents, plenty of shady places. The trail was mostly sand with more rocky terrain as you gain altitude. Very nice view of the lake.

I've hiked at Oakoasis a few times, it's not busy and has a great view of San Vicente reservoir. I found an ammo box near viewpoint - geocaching and a purple rock from Santee Rocks Facebook.

I hiked this with 2 kids and a dog and it was pretty fun. It does get hot though so bring a hat!

The trail is an easy walk of about an hour. The duration of your hike will mainly depend on how often you stop to capture the breathtaking landscape and the many wildflowers.

The trail mainly leads through shrubs. Along the way you constantly hear the bees humming. There is always a shaded section that lets you cool down. Still gets toasty, bring water.

Around halfway point is a short stretch where the trail goes up and especially down pretty steep. Shortly after you'll find yourself paving your way through a meadow, the trail almost disappears.

Tip: if you go to the spot where we started, that's the trail head with parking and restroom. It's right off of the main road. Not sure what the spot is that AllTrail has.

Lovely trail, although I was worried about the signs stipulating that there was a possibility of encountering mountain lions. The trail is pretty high up along the mountainside so when you get to the promise land (view of the lake) you've got some decent, elevated, breathtaking views.

Some parts swampy, some parts desert. Saw a ton of little frogs, some lizards, hawks, and great view of the reservoir halfway through. Maybe a quarter of the trail had shade but otherwise sunny. Great hike overall

A lot more tree cover than expected. Beautiful walk in spring.

I'll tell you what, it's magical during the spring ✨ You've got pink, yellow, and purple wildflowers blooming, a running creek, a waterfall, and the lake lookout! It's truly a hidden gem.

Love this trail, very scenic and serene. Got a little muddy at times but no big deal. There's a big parking lot so no issue there. There's also shade throughout the hike and the scenic point halfway through is beautiful. Very easy hike, would definitely go again.

Easy hike. Very nice scenery. Some cool geocaches along the trail.

The recent rains made this an incredible hike. Perfect for my two grandkids. Nothing like getting a little muddy when your a kid. Would have given it a 5 but it was too short for me.

Did this today with a 3 and 5 year old and had a great time. Just challenging enough, lots of variety of things to see. A beautiful outlook over a lake. We had a ball!

Very fun, easy trail. I went with my boyfriend and there was so much to explore. Some areas were incredibly green and other areas looked more desert like, the entire trail was gorgeous. We found a beautiful spot over looking the lake to eat our sandwiches and while we were eating we saw a Bald Eagle! We had so much fun and will definitely being going back!

This trail has different "scenes" which is enchanting. The view of the reservoir is beautiful.

I have been going on this trail for over 20 years. Some can say I grew up on this trail. It's the best trail if you have a couple hours and need to get out and get some fresh air and not feel like you are going to die after. It's great for horseback riding as well. Just look for snakes and people enjoying themselves on there horses and you'll be just fine.

Very easy hike, good for families. Very minimal inclines with rocks. The trail is just a loop. Most of the way you are surrounded by high shrubs so don't see anything, but once you reach the top there is a great view of the lake. Lots of rocks to climb along the loop. The first time we tried this trail our dog got some kind of thorn in his foot and couldn't walk, so we had to turn back. Came back another day without him to finish the loop. We did see a lot of dogs on this trail so it is dog friendly. Not sure I would do it again because it was a little too easy but seems great for families.

It was nice. At first you couldn't see any scenery because the shrubs around the trail were super high, but the garther you go, the more open it got. The view of the lake was beautiful.

I hike and ride horses there often. Great trail for a quick cardio workout or just to take your time and enjoy the scenery

RATTLESNAKES! This hike had a rattlesnake right on the trail- almost at the beginning. Not that you can judge a trail by that of course, but it is the perfect habitat for snakes so beware! It is extremely hot and has a lot of rocks. There is an amazing view about halfway through the trail, though. I don't recommend taking your old, small dog like we did, though. The sand in the trail was too hot for her!

Unscathed by the poison oak-lots of it on this quaint lil nature hike. Had a great time and the scenic outlook was rewarding! Lots of lil froggies-a lil bit of everything! Goodtimes!

Extremely quiet back in there, very peaceful. Watch your step! I found a rattlesnake 10 ft off of the main trail.

We did this hike on a spur of the moment and it was close by. We didn't know what to expect and when we arrived there was only one other vehicle parked. The area has some camping spots and seems to be extremely quiet all the time. Once you hit the scenic overlook area, there is not much more to see after it. The scenic overlook is beautiful and we loved just sitting there for awhile and talking.

The trail was short with a few steep inclines. Family friendly. Pleasant views for photos.
