Many investors flee to the safety of bonds when times get tough. But right now that's looking like a big mistake. Solid dividend stocks -- including blue chips -- are yielding well above 10-year U.S. Treasuries, and strangely, some of these dividend stalwarts pay higher yields than their bonds offer.

But that's only one of the reasons investors should be frightened of bonds now and instead put their investment dollars in a range of dividend stocks. Below I highlight three areas where you can stuff your cash and offer you a special free report that provides even more dividend ideas.

The trouble with bonds
Bonds are traditionally seen as safe, and not without some reason. They tend to be less volatile than stocks, offer regular interest payments, and have first priority in any liquidation. But with interest rates so low, bond investors are seeing a dicey proposition in the supposedly safe asset class. Take a look at three trends in bond-land.

1. Low interest rates
Investors who demand fixed income regardless of rates have been accepting almost any yield, even those below the level of inflation. Strong corporate borrowers such as Johnson & Johnson (NYSE: JNJ) have managed to score interest rates as low as 0.7%, and Google climbed aboard that gravy train as well, despite its own cash hoard.

But with such low rates investors are not only losing purchasing power, their bonds will decline in value if and when interest rates rise again.  

2. 100-year bonds
One solution to the low rates seems to be high-yielding 100-year bonds. But while investors might be able to earn higher interest rates from 100-year notes, it comes at a steep cost. How many centenarian companies can you name? Only a few of the highest-quality businesses will survive the next century. So while you might get higher rates now, there's added principal and business risk.

3. Weak bond covenants
With such low rates, investors have been willing to accept weaker lending terms, or covenants, in order to eke out marginally higher rates. Among other things, covenants constrain what actions the businesses can take and how much leverage they can take on, thus protecting bond investors' investment. If the economic situation gets dire, bond investors may not have the protections they think they have.

It's your move
With dubious opportunities for conservative bond investors, dividend stocks look like a very interesting alternative. As a stock investor you can take advantage of your companies borrowing at historically low rates and generating solid returns for you, plus you get a better income stream -- and one that grows over time, helping to overcome the ravages of inflation. Even the safest corporate bonds can't promise that.

Below I highlight three areas where you should consider parking some cash.

1. High-quality utilities
Perhaps the most obvious place to turn as a bond alternative is high-quality utilities. With a significant portion of their business derived from regulated operations, they can offer a steady return in almost any economic climate. Plus their high dividends help steady their share prices, meaning less volatility. And low volatility is one of the key principles behind my so-called world's best dividend portfolio, which has been trouncing the market lately.

Three of my favorite utilities are National Grid (NYSE: NGG), Southern Co. (NYSE: SO), and Exelon (NYSE: EXC).

Each company has a high dividend and a sustainable payout ratio. In January, I detailed why I liked National Grid, a stock that has gone on to perform nicely amid a rocky economic climate. In short, the U.K. utility offers indispensable hard assets, regulated operations, and some international diversity.

Exelon provides low-cost energy from its stable of nuclear plants, giving it a pricing advantage over fossil-fuel peers, though the company has fossil operations, too. Future environmental legislation limiting carbon emissions could help give the company an even bigger relative advantage since nuclear facilities generate minimal carbon.

Southern is interesting because of its good regulatory relationships, which allow it to raise rates, and the growing population in its service area (the U.S. South). While the stock is more expensive than the previous peers on a P/E basis, it's still a solid long-term addition to an income portfolio.

2. High-quality blue chips
You may not like to buy Johnson & Johnson's debt at a meager 0.7% rate, but the company is clearly taking advantage of the low-cost financing, and you can, too, by owning shares of the medical blue chip. The stock offers a 3.5% yield and trades at almost 16 times earnings. Over the last five years the company has managed to grow its payout by nearly 10% a year.

Intel (Nasdaq: INTC) should be another interesting play for income investors. With its 4.2% yield and dominant position in chips, investors shouldn't have to worry about this stock providing dividends for decades. It's grown its payout at a 13.5% clip over the last half-decade -- doubling its dividend in the process. The company has bought nearly $7.7 billion in stock over the last four quarters and trades at a cheap P/E of just 9.

3. Mortgage REITs
While the first two options above provide set-it-and-forget-it income investing, this option -- mortgage real estate investment trusts -- can juice yields for the short term. I especially like Annaly Capital (NYSE: NLY) and Chimera Investment (NYSE: CIM), whose business models thrive on low rates. They both pay double-digit yields and could be a good addition to a diversified portfolio. Their yields won't stay high forever, though, so you'll have to be vigilant about rising rates.

Foolish bottom line
While many investors assume that bonds are simply safer than stocks in all market conditions, a portfolio of high-quality dividend stocks can provide better yields and long-term appreciation.
